CD3 Flow Cytometry is a laboratory test that detects and measures CD3, a protein complex found on the surface of mature T lymphocytes. Using flow cytometry, it helps identify and characterize T-cell populations in blood, bone marrow, or tissue samples. The test is needed to assess T-cell numbers and patterns and support the diagnosis and classification of T-cell leukemias, lymphomas, immune disorders, and other hematological conditions.
It may be useful when evaluating suspected T-cell leukemia or lymphoma, unexplained changes in lymphocyte populations, immune-system abnormalities, and certain hematological disorders.
No. CD3 is one marker within a broader flow-cytometry panel. Diagnosis requires correlation with other markers, blood counts, clinical findings, morphology, and sometimes genetic or molecular tests.
CD3-positive means that the evaluated cells express CD3, supporting their identification as T lymphocytes. The overall significance depends on the proportion and characteristics of these cells.
CD3-negative means that significant CD3 expression was not detected on the evaluated cells. This may be expected for non-T cells but requires interpretation based on the cell population being investigated.
Yes. CD3 is a characteristic marker of mature T lymphocytes and is expressed on most normal peripheral T cells.
