An elevated erythrocyte sedimentation rate (ESR), often referred to as a “high sed rate,” is a common blood test finding that signals the presence of inflammation somewhere in the body. Because inflammation plays a central role in many diseases—from infections and autoimmune disorders to cancers and tissue injuries—an increase in ESR can be an early clue prompting further investigation. In this article, we will explore what a high ESR means, the different methods used to measure it, the many conditions that can cause it to rise, the typical symptoms patients may experience, and the broad range of diagnostic tests clinicians use to pinpoint the underlying cause. By understanding the significance and limitations of ESR, patients and healthcare providers can use this simple yet powerful test more effectively in monitoring health and guiding treatment decisions.
The erythrocyte sedimentation rate measures how quickly red blood cells (erythrocytes) settle to the bottom of a tall, thin tube in one hour. When inflammation is present, proteins such as fibrinogen cause red blood cells to stick together and form stacks called rouleaux. These stacks sink faster, resulting in a higher millimeter-per-hour (mm/hr) reading. A normal ESR varies by age and sex—typically up to 15 mm/hr in men and up to 20 mm/hr in women—so values above these thresholds are considered elevated. An ESR above 100 mm/hr is especially concerning and often points to serious conditions like severe infections, malignancies, or giant cell arteritis MedlinePlusPubMed.
Beyond its basic mechanism, ESR is valued for its simplicity, low cost, and sensitivity to changes in inflammatory activity. Unlike more specific markers such as C-reactive protein (CRP), ESR can remain elevated longer after inflammation subsides, making it useful for tracking chronic conditions. However, because it is influenced by many non‑inflammatory factors—such as age, anemia, and pregnancy—it is interpreted alongside clinical findings and other laboratory tests rather than on its own PubMedAAFP.
Types of ESR Measurement Methods
There are several methods for measuring ESR, each with its own advantages in sensitivity, speed, and ease of use:
Westergren Method: Considered the gold standard, this method uses a 200 mm-long tube filled with diluted blood. After one hour, the height of the clear plasma column above the red cells is measured in millimeters. It is highly sensitive to mild inflammation but requires a longer tube and careful technique NCBIThe Blood Project.
Wintrobe Method: This uses a shorter, 100 mm-long tube with a narrower diameter, making it less sensitive—especially for lower ESR values—but simpler for labs without Westergren equipment. Results are also read after one hour but have a lower maximum detectable value due to the shorter tube length The Blood ProjectHealthline.
Micro‑ESR: Uses a smaller volume of blood and microhematocrit tubes. It’s faster and useful when sample volume is limited, such as in pediatrics, but can be less precise.
Automated Analyzers: Modern hematology instruments measure ESR through optical or mechanical methods, offering rapid, standardized results with minimal manual handling.
Each method aims to balance sensitivity, speed, and resource availability. Clinicians choose based on the laboratory’s capabilities and the level of precision needed for patient management.
Pathophysiology of Elevated ESR
At its core, ESR reflects changes in blood protein composition and red cell behavior. During inflammation, the liver increases production of acute‑phase proteins like fibrinogen, immunoglobulins, and complement factors. These proteins coat red blood cells, promoting the formation of stacked aggregates (rouleaux). Rouleaux have a smaller overall surface area relative to individual cells and thus settle faster in a gravity column. The degree of elevation generally correlates with the intensity of the inflammatory stimulus.
In addition to fibrinogen, other plasma components—such as elevated globulins in multiple myeloma or low albumin in chronic disease—can dramatically alter rouleaux formation. Red blood cell characteristics also play a role: cells that are too large, misshapen (as in sickle cell disease), or reduced in number (anemia) can change ESR readings independently of inflammation. Because of these multiple influences, ESR is best seen as a global marker of altered plasma and red cell properties rather than a specific test for any one disease PubMedPMC.
Factors Affecting ESR Results
Several non‑disease factors can impact ESR measurements, sometimes leading to misinterpretation if not considered:
Age and Sex: ESR normally increases with age and is slightly higher in females than males.
Pregnancy: Elevated estrogen levels raise fibrinogen, causing higher ESR.
Anemia: Fewer red cells means less blood viscosity, so cells sink faster.
Red Cell Shape: Sickle or spherical cells resist stacking, potentially lowering ESR despite inflammation.
Technical Variables: Delay in testing, tube angle, temperature fluctuations, and improper anticoagulant ratios can all skew results.
Obesity and Metabolic Syndrome: Chronic low‑grade inflammation in these states can raise baseline ESR.
Smoking and Alcohol: Both can alter plasma proteins and red cell function.
Medications: Drugs like oral contraceptives or steroids may affect acute phase protein levels.
Awareness of these factors helps clinicians decide when an elevated ESR truly reflects new inflammation versus known physiological or technical influences ELITechGroup GlobalPMC.
