CD45 Count

CD45, also known as leukocyte common antigen (LCA), is a protein present on the surface of all mature leukocytes, including lymphocytes (B cells and T cells), monocytes, and granulocytes. It plays a key role in immune cell signaling, activation, and regulation. The CD45 Count test uses specific antibodies in an IHC procedure to detect this protein in the sample, helping doctors confirm whether abnormal cells are of hematopoietic origin.

The CD45 Count test is recommended for individuals with symptoms suggestive of blood cancers or immune system disorders, such as unexplained fatigue, fever, night sweats, weight loss, or enlarged lymph nodes, as well as those with a family history of leukemia or lymphoma or exposure to risk chemicals (e.g., benzene, pesticides). It is useful for diagnosing leukemias and lymphomas, differentiating these blood cancers from non-hematopoietic tumors, determining the stage of certain blood cancers, monitoring treatment effectiveness, and assessing conditions affecting B and T cell activity.

For this test, provide the original histopathology report, clinical history, and any relevant radiological information before the test, as these are important for accurate interpretation. Inform the doctor about all the medications, supplements, and underlying illnesses, as all these factors may affect the test results.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate and always consult a doctor to understand the test results correctly.
