The CD3 Test is a laboratory test that measures the presence of CD3 on T-cells (a type of white blood cell). CD3 is a protein complex found on the surface of T-lymphocytes, which play a crucial role in the immune system, particularly in immune response and regulation. CD3 is essential for the activation and function of T-cells during an immune response.
This test is typically performed using flow cytometry, a technique that can detect and measure the amount of CD3 protein on T-cells in blood or tissue samples.

    Description

    Why It’s Done:

    The CD3 test is used for several purposes:
    • Diagnosing immune system disorders, such as T-cell immunodeficiencies or autoimmune diseases.
    • Evaluating T-cell function and the immune status in patients with suspected immunodeficiency or autoimmune diseases.
    • Monitoring patients with HIV/AIDS to assess the status of their immune system, as T-cell counts (specifically CD3+ T-cells) are crucial in the progression of the disease.
    • Diagnosing hematological cancers like T-cell leukemia or lymphoma, as the CD3 marker is often found on the surface of malignant T-cells.
    • Post-transplantation monitoring to evaluate immune system recovery and graft-versus-host disease (GVHD) risk.

    Preparation:

    • No special preparation is required for the CD3 test.
    • Inform your healthcare provider about any medications, particularly immunosuppressive drugs, which may affect the test results.
    • A blood sample is typically collected from a vein in your arm for flow cytometry analysis.
