NK‑cell Lymphocytosis

Natural killer (NK) cells are a type of white blood cell critical to your body’s first line of defense against infected or cancerous cells. They act without prior sensitization, identifying and ...

Lymphocytosis means there are more lymphocytes than usual in the blood. Lymphocytes are a type of white blood cell. They include T cells, B cells, and NK cells. When the extra lymphocytes are mainly ...
Mantle cell lymphocytosis refers to an abnormal increase in malignant B-lymphocytes originating from the “mantle zone” of lymph nodes—a pattern characteristic of mantle cell lymphoma (MCL). In simple ...
Monoclonal B‑cell lymphocytosis (MBL) is a blood condition in which a small, clonal population of B‑lymphocytes—white blood cells that normally help fight infection—circulates in the peripheral blood ...
B‑cell lymphocytosis (also called monoclonal B‑cell lymphocytosis, or MBL) means your body has too many identical B‑cells in the blood. These cells come from one parent cell that makes lots of ...
Chronic lymphocytosis is a condition where your blood contains too many lymphocytes— a type of white blood cell—over a long period. Normally, lymphocytes make up about 20–40% of white blood cells and ...
Acute or transient lymphocytosis refers to a temporary increase in the absolute lymphocyte count (ALC) in peripheral blood above the normal range (usually >4 × 10⁹/L in adults). ...
Clonal (Primary) Lymphocytosis is a blood disorder characterized by an abnormally high number of lymphocytes—white blood cells that play a critical role in the immune system—arising from a single ...
Reactive (secondary) lymphocytosis is a condition in which the number of lymphocytes—a type of white blood cell vital for fighting infections—rises above its normal range as a direct response to ...
Absolute lymphocytosis occurs when the number of lymphocytes in the blood rises above normal. Lymphocytes are a type of white blood cell that help your body fight infections and diseases. When their ...
Relative lymphocytosis is a laboratory finding in which lymphocytes—one of the major types of white blood cells—make up more than 40% of the total white blood cell (WBC) count, despite a normal ...
Lymphocytosis means your blood has more lymphocytes than usual. Lymphocytes are a kind of white blood cell that help you fight infections and control immune responses. There are three main lymphocyte ...
Lymphocytes are a type of white blood cell crucial for fighting infections and maintaining immune balance. In healthy adults, lymphocyte counts typically range between 1,000 and 4,800 cells per ...
Moderate lymphocytosis refers to an increase in the absolute lymphocyte count (ALC) above the normal upper limit (approximately 4.0 × 10⁹/L in adults) but typically below levels seen in severe ...
Lymphocytes are a type of white blood cell that help protect your body against infections and other foreign invaders. In adults, a normal lymphocyte count is between about 1,000 and 4,800 cells per ...
Lymphocytes are a type of white blood cell that help your immune system recognize, remember, and attack germs and abnormal cells. They include B cells (make antibodies), T cells (direct and kill ...
