Bernard–Soulier Thrombopathy (Bernard–Soulier Syndrome)

Bernard–Soulier thrombopathy is a rare, inherited bleeding disorder where platelets—the tiny cell fragments that plug holes in injured blood vessels—are both too large (often called “giant platelets”) and too few in number (mild-to-moderate thrombocytopenia). Even more importantly, these platelets do not stick properly to injured vessel walls because they lack or have faulty versions of a surface “grip” called the GPIb-IX-V receptor. This receptor is the docking site for von Willebrand factor (VWF), the protein that tethers platelets to the damaged vessel so a clot can start. When this grip is missing or not working, people bleed more easily, especially from the nose, gums, skin, and with menstruation or surgery. NCBI+2Orpha+2

Bernard–Soulier syndrome (BSS) is a rare, inherited bleeding disorder. Platelets are fewer in number and much larger than normal, and—most importantly—the platelet “plug” does not stick well to damaged blood vessels because part of the GPIb-IX-V receptor is missing or not working. This makes nosebleeds, gum bleeding, easy bruising, heavy periods, and longer bleeding after injuries or procedures more likely. BSS is usually inherited in an autosomal recessive way, starts in childhood, and ranges from mild to severe. Diagnosis often shows macrothrombocytopenia on a blood smear, absent/markedly reduced ristocetin-induced agglutination, and confirmation by genetic testing (GP1BA, GP1BB, GP9). Genetic Diseases Center+3BioMed Central+3haematologica.org+3

The condition is usually passed down in families. Classically it is autosomal recessive, which means a person is affected when they inherit one faulty gene from each parent. Rare, autosomal dominant (monoallelic) forms cause milder problems. The genes most often involved are GP1BA, GP1BB, and GP9, which encode the three key parts of the GPIb-IX-V receptor complex. NCBI+1

Other names

Doctors and textbooks may use several alternative names for the same disease:

• Bernard–Soulier syndrome (BSS)

• Hemorrhagiparous (or hemorrhagiparous) thrombocytic dystrophy (older term)

• GPIb-IX-V complex deficiency, platelet GPIb deficiency, or macrothrombocytopenia, Bernard–Soulier type (descriptive names emphasizing the mechanism and big platelets)
  All of these point to the same problem: platelets that are large, reduced in number, and unable to bind VWF because their GPIb-IX-V receptor is missing or malfunctioning. NCBI+1

Types

1. Biallelic (classic) BSS. Two pathogenic variants (one from each parent) in GP1BA, GP1BB, or GP9 cause severe reduction or complete loss of the GPIb-IX-V receptor on platelet surfaces. This is the most common and generally more symptomatic form. haematologica.org

2. Monoallelic (dominant) BSS. A single variant in GP1BA can produce a qualitative defect (the receptor reaches the surface but doesn’t bind VWF normally). Patients often have milder bleeding and moderately enlarged platelets. haematologica.org

3. Qualitative vs. quantitative defects. Some variants mainly lower the amount of receptor (quantitative), while others impair its function (qualitative). Either pathway reduces effective platelet adhesion to damaged vessels. haematologica.org

4. Acquired BSS (“pseudo-BSS”). A Bernard–Soulier–like picture can appear later in life when other conditions or autoantibodies target GPIb-IX, or when certain bone-marrow diseases reduce its expression. The lab pattern may mimic inherited BSS, but the cause is not genetic. haematologica.org+1

Causes

In inherited BSS, “cause” means the biologic mechanism by which a gene change stops platelets from grabbing VWF. Below are 20 ways this can happen or be mimicked.

1. Missense variants in GP1BA. A single amino-acid change warps GPIbα’s VWF-binding pocket, so platelets can’t latch onto VWF. haematologica.org

2. Nonsense variants in GP1BA. A premature “stop” cuts GPIbα short; the incomplete protein is degraded, so the receptor never forms. haematologica.org

3. Frameshift variants in GP1BA. Small insertions/deletions scramble the code and prevent a stable receptor subunit from being produced. haematologica.org

4. Splice-site variants in GP1BA. Incorrect RNA splicing removes or adds pieces, yielding misfolded or unstable GPIbα. haematologica.org

5. Missense variants in GP1BB. The GPIbβ subunit helps assemble the complex; harmful changes block assembly and surface expression. haematologica.org

6. Nonsense/frameshift variants in GP1BB. Truncated GPIbβ cannot chaperone the complex to the platelet surface. haematologica.org

7. Variants in GP9 (GPIX). Faulty GPIX destabilizes the entire complex, so very little GPIb-IX-V reaches the surface. haematologica.org

8. Combined or compound heterozygous variants. Two different harmful variants—one on each allele—together prevent normal receptor expression. haematologica.org

9. Variants that impair intracellular trafficking. Some changes let subunits form but trap the complex inside the cell, away from the membrane. haematologica.org

10. Variants that block VWF binding despite normal expression. The receptor is present but can’t bind VWF effectively (a qualitative defect). haematologica.org

11. Dominant (monoallelic) GP1BA variants. A single altered copy reduces function enough to produce a milder macrothrombocytopenia with bleeding. haematologica.org

12. Large gene deletions/duplications involving GP1BA/GP1BB/GP9 that remove key coding regions. haematologica.org

13. Promoter or regulatory variants that sharply lower gene expression, leaving too little receptor on platelets. haematologica.org

14. Founder effects/consanguinity. In some communities, one pathogenic variant is more common, increasing the chance of biallelic inheritance. National Organization for Rare Disorders

15. Acquired anti-GPIb/IX autoantibodies. The immune system targets the receptor, mimicking BSS with poor ristocetin response and bleeding. rpthjournal.org+1

16. Myeloid neoplasms or marrow disorders that down-regulate GP1BB/complex expression, producing a Bernard–Soulier–like phenotype. haematologica.org

17. Drug-related immune reactions (rare) forming antibodies against GPIb/IX and causing a BSS-like pattern. ScienceDirect

18. GATA2-related marrow disease with pseudo-BSS, where a broader bone-marrow problem secondarily impairs GPIb-IX function. PMC

19. Transcription/processing defects (mRNA instability) that reduce the amount of usable GP1BA/GP1BB/GP9 transcript. haematologica.org

20. Post-translational defects (abnormal glycosylation or folding) that destabilize the receptor complex before it reaches the platelet surface. haematologica.org

Symptoms

The bleeding pattern is mucocutaneous (skin and mucous membranes). Severity varies even within families.

1. Easy bruising. Large, frequent bruises after minor bumps. National Organization for Rare Disorders

2. Nosebleeds (epistaxis). Recurrent or prolonged, especially in childhood. National Organization for Rare Disorders

3. Gum bleeding. With brushing or dental work. Medscape

4. Prolonged bleeding from small cuts. The initial plug is weak and oozing continues. Medscape

5. Petechiae and purpura. Small red/purple skin spots from superficial bleeding. National Organization for Rare Disorders

6. Heavy menstrual bleeding (menorrhagia). Flow is heavy or lasts longer than usual. Medscape

7. Bleeding after tooth extraction. Oozing may persist and require local measures. Medscape

8. Bleeding after surgery or childbirth. May be more than expected without careful planning. Medscape

9. Gastrointestinal bleeding. Occasional, especially with added triggers (e.g., ulcers). Medscape

10. Hematuria (blood in urine). Less common, but reported. National Organization for Rare Disorders

11. Prolonged bleeding after trauma. Even small injuries can ooze for hours. Medscape

12. Anemia from chronic blood loss. Tiredness and pallor can follow repeated bleeding. National Organization for Rare Disorders

13. Post-viral or medication-worsened bleeding. Intercurrent illnesses/NSAIDs can unmask symptoms. NCBI

14. Rare serious bleeds. Intracranial hemorrhage is uncommon but has been described in severe cases. PubMed

15. Childhood onset, lifelong tendency. Most patients show symptoms in early life that persist. National Organization for Rare Disorders

Diagnostic tests

No single test stands alone. Doctors combine history, blood counts, specialized platelet tests, and sometimes genetics. A classic lab clue is absent or very low ristocetin-induced platelet agglutination that does not correct when normal plasma is added, plus reduced/absent CD42b (GPIbα) by flow cytometry, and a blood smear with giant platelets. NCBI+1

A) Physical examination and bedside assessment

1. Bleeding history and pattern. Focus on mucocutaneous bleeds (nose, gums, skin), heavy menses, and bleeding after surgery/dental work; this pattern points toward a platelet adhesion defect rather than a clotting-factor deficiency. Medscape

2. Family history. Siblings or cousins with similar issues and parental consanguinity suggest an inherited disorder like BSS. National Organization for Rare Disorders

3. Medication review. NSAIDs and some herbs worsen platelet function and can mask or magnify symptoms; documenting exposures helps interpretation of tests. NCBI

4. Bleeding assessment tools (e.g., ISTH-BAT). A structured score helps quantify lifetime bleeding and select patients for advanced platelet testing. Wiley Online Library

B) “Manual” or office-based screening tests

5. Peripheral blood smear (light microscopy). A simple slide often shows very large platelets; this is one of the earliest and most useful clues. Medscape

6. Bleeding time (Ivy; historical). Now largely replaced, but historically prolonged in BSS; modern labs prefer instrumented tests. haematologica.org

7. PFA-100/PFA-200 closure time. A cartridge-based screen of primary hemostasis; closure times are often prolonged in BSS, prompting definitive studies. Wiley Online Library

8. Structured menstrual bleeding score (PBAC). Helps document severity of menorrhagia and track response to care. Medscape

C) Laboratory and pathological tests (core of the diagnosis)

9. Complete blood count (CBC). Platelet count is low to moderately low, while the mean platelet volume is high—a macrothrombocytopenia pattern. MedlinePlus

10. Ristocetin-induced platelet agglutination (RIPA) or aggregometry. Absent or markedly reduced agglutination with ristocetin is a hallmark of BSS and does not correct with normal plasma (distinguishes BSS from most VWF defects). Responses to other agonists (ADP, collagen) are relatively preserved. PubMed+1

11. Flow cytometry for platelet glycoproteins. Reduced/absent CD42b (GPIbα) and often CD42a (GPIX) confirm loss of the receptor; CD41/CD61 (GPIIb/IIIa) are typically normal (helps distinguish from Glanzmann thrombasthenia). JTH Journal+1

12. Genetic testing (targeted or NGS panels). Identifies pathogenic variants in GP1BA, GP1BB, or GP9 and clarifies biallelic vs monoallelic forms, which can inform prognosis and family counseling. NCBI

13. VWF panel (antigen and activity). Usually normal in BSS; this rules out von Willebrand disease, which can look similar clinically. Wiley Online Library

14. Western blot (immunoblot) for glycoproteins. Research/advanced labs can show reduced or absent GPIb-IX-V proteins directly. haematologica.org

15. Electron microscopy of platelets. Shows giant platelets and can assess granules and membrane systems; supportive in difficult cases. haematologica.org

16. Viscoelastic testing (TEG/ROTEM) with platelet mapping. Not diagnostic for BSS but may document a primary hemostasis defect and help manage bleeding in the operating room. Thieme

D) Electrodiagnostic platelet function tests (instrumented tests using electrical or signal detection)

17. Whole-blood impedance aggregometry (MEA). Measures electrical impedance as platelets aggregate; shows poor ristocetin-driven response in BSS and can track day-to-day changes. JTH Journal

18. Lumi-aggregometry (ATP secretion). Detects light emission from ATP release; combined with aggregation traces, it helps exclude other secretion defects when evaluating suspected BSS. Wiley Online Library

19. Flow-based adhesion assays (microfluidic). Specialized centers may test platelet adhesion to VWF under shear; BSS platelets adhere poorly due to missing GPIb. Wiley Online Library

E) Imaging and procedure-based tests (to find bleeding sources or complications)

20. Imaging tailored to the bleed. Because BSS causes mucocutaneous bleeding, imaging is not required to diagnose the disorder but is vital when there is concern for complications: CT or MRI head after significant head trauma, endoscopy for gastrointestinal bleeding, pelvic ultrasound for heavy menses, and nasal endoscopy for recurrent severe epistaxis.

Description: A written plan explains your baseline risks, what to do for nose/gum bleeds, when to use prescribed medicines, and when to go to hospital. It lists drugs to avoid and contacts for urgent care.
Purpose: Reduce panic, delays, and errors during a bleed or procedure.
Mechanism: Preparedness reduces exposure to triggers (NSAIDs/trauma), prompts early use of local pressure or antifibrinolytics, and ensures hospitals arrange HLA-matched platelets when needed. NCBI+1

2) Medical alert identification
Description: Wear a bracelet/card stating “Inherited platelet function disorder—Bernard–Soulier syndrome—avoid antiplatelets/NSAIDs; special perioperative plan.”
Purpose: Speed correct treatment in emergencies.
Mechanism: Alerts clinicians to avoid drugs that worsen bleeding and to arrange platelets/antifibrinolytics promptly. Medscape

3) Bleeding-safe dental care
Description: Dental checkups, soft toothbrush, chlorhexidine when indicated, and planned extractions/periodontal work with local hemostasis (suturing, oxidized cellulose, fibrin sealant) plus antifibrinolytics.
Purpose: Prevent and control gum/dental bleeding.
Mechanism: Gentle technique plus local pro-coagulant materials reduce mucosal oozing where platelets normally play a key role. Medscape

4) First-aid for nosebleeds (epistaxis protocol)
Description: Sit up, lean forward, pinch soft part of nose firmly for 10–15 minutes, ice on the bridge; avoid packing objects; use topical hemostatic foam if directed.
Purpose: Stop nosebleeds quickly at home.
Mechanism: Direct pressure and vasoconstriction compress bleeding vessels while clots stabilize despite weak platelet adhesion. Cleveland Clinic

5) Menstrual management counseling
Description: Track cycles, plan for heavy days (pads, work/school planning), discuss hormonal options with gynecology; ensure access to antifibrinolytics.
Purpose: Reduce iron loss and improve quality of life.
Mechanism: Hormones thin/stabilize endometrium; antifibrinolytics protect clots so mucosal bleeding is less. Cleveland Clinic+1

6) Iron repletion and anemia prevention
Description: Screen ferritin and hemoglobin; use oral/IV iron when low.
Purpose: Replace iron lost from chronic mucosal bleeding/heavy periods.
Mechanism: Restores red cell mass and oxygen delivery; does not fix platelet function but reduces fatigue/dyspnea from anemia. Cleveland Clinic

7) Local hemostatic materials in clinics
Description: Oxidized cellulose, gelatin sponges, microfibrillar collagen, and fibrin sealants applied during dental/ENT/minor surgery.
Purpose: Provide a local “plug” when platelet adhesion is poor.
Mechanism: Create a matrix for clotting factors and red cells to form a stable clot independent of GPIb-IX-V. U.S. Food and Drug Administration

8) HLA-matched/antigen-negative platelet planning
Description: For elective surgery or childbirth, arrange HLA-matched or cross-match compatible platelets.
Purpose: Improve response and reduce alloimmunization.
Mechanism: Matching reduces immune destruction of transfused platelets, supporting hemostasis when endogenous platelets cannot adhere. NCBI

9) Peri-procedural protocols
Description: Multidisciplinary plans for endoscopy, dental extractions, delivery, or operations—timing antifibrinolytics, platelet transfusion, and local hemostasis.
Purpose: Prevent unexpected bleeding.
Mechanism: Increases circulating functional platelets at incision time and protects clots at mucosal surfaces. Medscape

10) Trauma risk reduction & safe sports
Description: Choose low-impact activities (swimming, walking, cycling with helmet) and protective gear.
Purpose: Lower trauma-related bleeding.

11) Avoidance of antiplatelet/anticoagulant agents unless essential
Description: Avoid aspirin, ibuprofen, naproxen; check OTC/herbal products.
Purpose: Prevent worsening platelet function.
Mechanism: NSAIDs inhibit COX-1, reducing thromboxane A2; in BSS, any extra platelet inhibition magnifies bleeding. Medscape+1

12) Vaccination & infection control
Description: Keep routine vaccines up to date; treat infections that could provoke nose/gum bleeding (e.g., sinusitis/gingivitis).
Purpose: Reduce bleeding triggers.
Mechanism: Fewer infections means fewer inflamed mucosae prone to oozing; vaccines themselves do not treat BSS but keep you healthier. PMC

13) Nasal/ENT care for chronic epistaxis
Description: Humidification, saline sprays, petrolatum to anterior septum; medical review for cauterization if recurrent.
Purpose: Protect fragile nasal mucosa.
Mechanism: Moist mucosa cracks less; cautery seals superficial vessels. Cleveland Clinic

Dietary molecular supplements

1) Iron (elemental) — Dose: common oral 40–65 mg daily or as advised; IV if needed. Function/Mechanism: Restores hemoglobin and iron stores lost from chronic mucosal bleeding/heavy periods; improves energy but does not change platelet function. Avoid taking with tea/coffee; consider vitamin C-rich foods to aid absorption. Cleveland Clinic

2) Folic acid — Dose: 0.4–1 mg/day typical. Function/Mechanism: Supports red-cell production when losses are chronic; prevents megaloblastic anemia that can co-exist with iron deficiency. Cleveland Clinic

3) Vitamin B12 — Dose: per deficiency; oral or IM. Function/Mechanism: Corrects B12 deficiency anemia from dietary causes or malabsorption; improves oxygen-carrying capacity. Cleveland Clinic

4) Vitamin C — Dose: 100–500 mg/day typical dietary supplement. Function/Mechanism: Supports collagen and capillary integrity; helps iron absorption; may reduce gum bleeding from gingivitis but does not treat BSS itself. Cleveland Clinic

5) Calcium + Vitamin D — Dose: per age/sex; dietary first. Function/Mechanism: Bone health if hormonal therapy or reduced activity is needed; indirect support for overall wellness. Cleveland Clinic

6) Oral rehydration & electrolytes during heavy bleed days — Dose: per product. Function/Mechanism: Maintains perfusion and reduces symptomatic dizziness while seeking medical care; not a hemostatic. Medscape

7) Protein-rich nutrition (dietary, not pill) — Dose: balanced intake. Function/Mechanism: Supplies amino acids for tissue repair and wound healing after procedures. Medscape

8) Multivitamin without high-dose vitamin E — Dose: daily standard. Function/Mechanism: Covers general micronutrients while avoiding high-dose vitamin E, which may have antiplatelet effects. Medscape

9) Avoid “pro-bleeding” botanicals — Not a supplement to take, but a critical dietary rule: avoid ginkgo, garlic capsules, high-dose fish oil, ginger extracts, turmeric/curcumin concentrates, which may impair platelet function. Mechanism: COX inhibition or platelet signaling interference. Medscape

10) Diet pattern for iron: “heme-plus-C” — Strategy: combine heme iron (meat/fish) with vitamin C (citrus, guava, peppers) to boost absorption; limit tea/coffee with iron pills. Mechanism: Vitamin C reduces ferric to ferrous iron; tannins inhibit absorption. Cleveland Clinic

Immunity-booster / regenerative / stem-cell drugs

Honest, safety-first note: There are no approved “immunity booster” drugs and no approved stem-cell drugs that correct Bernard–Soulier thrombopathy. The true disease mechanism is a platelet adhesion receptor defect, not an immune deficiency. Experimental directions include hematopoietic stem cell transplantation (HSCT) in severe, transfusion-dependent cases and gene/cell therapies under research; these are procedures or trials, not take-home medicines. Any claims of pills that “regenerate” platelets in BSS should be treated with caution. PMC+1

What’s being explored (research/advanced care):

1. HSCT (bone-marrow transplant) in select severe cases—can restore donor-derived normal platelets but carries significant risks; considered only in expert centers. PMC

2. Gene therapy concepts correcting GP1BA/GP1BB/GP9 in patient-derived hematopoietic stem cells or iPSCs (preclinical/early translational). PMC

3. rFVIIa as a bypass hemostatic (rescue) when platelets aren’t an option—already covered above. PMC

4. Improved platelet matching strategies to limit alloimmunization and preserve transfusion efficacy over time. NCBI

5. Hormonal suppression for menorrhagia (CHC/LNG-IUS)—symptom control, not regeneration. hog.org

6. Clinical-trial enrollment in inherited platelet disorder programs at specialized centers. MDPI

Surgeries / procedures

1) Nasal cauterization (chemical/electrocautery)
What: ENT seals fragile nasal vessels causing recurrent nosebleeds.
Why: Reduce frequent epistaxis that resists home care and antifibrinolytics. Cleveland Clinic

2) Dental extractions/periodontal surgery with hemostatic plan
What: Carefully planned dental work using local hemostatics plus TXA/ACA ± platelet support.
Why: Treat dental disease while controlling mucosal bleeding risk. FDA Access Data

3) Obstetric delivery with planned hemostasis
What: Vaginal or cesarean birth with platelets on standby, TXA protocol, and active postpartum hemorrhage prevention.
Why: Childbirth has high bleeding risk; planning reduces complications. PMC

4) Endoscopic/surgical treatment of GI bleeds
What: Endoscopic clipping/cautery/injection; surgery rarely if uncontrolled.
Why: Control focal sources of bleeding with local measures plus systemic support. Medscape

5) Hysterectomy or endometrial ablation (last-line)
What: Remove uterus or ablate endometrium in refractory, life-altering menorrhagia after medical options fail.
Why: Definitive control of menstrual blood loss in extreme cases. Cleveland Clinic

(Splenectomy is generally not helpful for BSS because it does not fix the adhesion defect and may raise thrombotic/infectious risks; it is not standard.) PMC

When to see doctors (or seek urgent care)

• Heavy, persistent nosebleed or gum bleed that doesn’t stop after 15–20 minutes of correct pressure and measures. Cleveland Clinic

• Black/tarry stools, vomiting blood, or bright red rectal bleeding. Medscape

• Heavy periods soaking pads hourly, passing large clots, or causing dizziness/fainting—especially with low iron symptoms (fatigue, pallor). Cleveland Clinic

• Before any invasive procedure (dental extraction, endoscopy, surgery, childbirth)—even if “minor.” Medscape

• After trauma, especially head injury (seek emergency evaluation). Medscape

What to eat and what to avoid

Eat more of:

1. Iron-rich foods (beef, liver, fish, legumes) to prevent anemia.

2. Vitamin C-rich foods (guava, citrus, bell pepper) with iron to boost absorption.

3. Protein-rich foods (eggs, dairy, pulses) to aid healing after procedures.

4. Leafy greens (folate) to support red cell production.

5. Plenty of fluids during/after bleeds to feel better while seeking care. Cleveland Clinic

Limit/avoid:

1. Alcohol excess (can worsen bleeding).
2. Ginkgo, high-dose garlic, ginger, fish-oil concentrates, turmeric/curcumin extracts (possible antiplatelet effects).
3. NSAIDs (aspirin/ibuprofen/naproxen) unless a specialist says otherwise.
4. Very hard/crunchy foods immediately after dental procedures.
5. Tea/coffee with iron pills (cut iron absorption—space by a few hours). Medscape

Frequently asked questions

1) Is Bernard–Soulier the same as “low platelets”?
No. Platelets are often low and large, but the main problem is poor adhesion due to a GPIb-IX-V defect. BioMed Central

2) Can it be cured with medicine?
No. There’s no pill that restores the missing receptor. Care prevents and treats bleeds; platelets are given for significant bleeds/procedures. NCBI

3) Is desmopressin (DDAVP) helpful?
Not reliably. Some centers may trial it in mild cases, but authoritative sources say no established role in classic BSS. NCBI

4) What happens during a planned surgery?
A specialist plan uses HLA-matched platelets, local hemostatics, and antifibrinolytics; rFVIIa is a backup if platelets aren’t an option. NCBI+1

5) Are there medicines I must avoid?
Yes: aspirin and NSAIDs (and many “natural blood thinners”). Always check with your team before new meds or supplements. Medscape

6) How common is BSS?
Very rare—about 1 per 1,000,000 people; many are misdiagnosed. bleedingdisordersnc.org+1

7) Can women with BSS have healthy pregnancies?
Yes—with early planning, antifibrinolytics, and platelet support as needed. PMC

8) What if I don’t respond to platelet transfusions?
Alloimmunization can reduce response; HLA-matched platelets or rFVIIa rescue may be used. NCBI+1

9) Do I need genetic testing?
It confirms the diagnosis and helps family planning but is not mandatory for acute care. MedlinePlus

10) Can children play sports?
Yes—prefer low-impact sports with protective gear; avoid high-collision contact sports. Medscape

11) Does diet fix BSS?
No. Diet supports overall health and anemia prevention; it does not repair platelet adhesion. Cleveland Clinic

12) Is rFVIIa safe?
It can help in difficult cases but carries thrombosis risk; specialists weigh risks/benefits. U.S. Food and Drug Administration

13) Are “stem-cell pills” real for BSS?
No. HSCT is a complex hospital procedure, not a pill; gene therapy is investigational. PMC

14) Why am I told to avoid intramuscular injections?
IM shots can cause deep muscle hematomas; alternative routes are preferred where possible. Medscape

15) What should be in my emergency letter?
Diagnosis, baseline counts, medication allergies, “avoid NSAIDs/antiplatelets,” prior responses to platelets/TXA/rFVIIa, and your hematology contact. Medscape
