The 12 tests in this panel

What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

  • CD3+ T Cells, absolute

    How many T cells are in a microliter of blood. T cells are white blood cells that direct and carry out much of the immune response.

    16+
    622–2,402 cells/µL

  • CD3+ T Cells, percent

    The share of your lymphocytes that are T cells, which carry a marker called CD3. The absolute count is usually more useful.

    65+
    62–89 %

  • CD4+ T Helper Cells, absolute

    The number of CD4+ T helper cells in a microliter of blood. These white blood cells help direct your immune response.

    65+
    490–1,600 cells/µL

  • CD4+ T Helper Cells, percent

    The share of your lymphocytes that are CD4+ T helper cells. It is read together with the CD4 count.

    65+
    35–68 %

  • CD8+ T Cells, absolute

    The number of CD8+ T cells in a microliter of blood. These cytotoxic cells destroy infected or damaged cells.

    65+
    150–1,050 cells/µL

  • CD8+ T Cells, percent

    The share of your lymphocytes that are CD8+ T cells. It is read together with the CD8 count and the CD4 results.

    65+
    10–46 %

  • CD4/CD8 Ratio

    CD4 helper T cells divided by CD8 cytotoxic T cells. It shows how those two groups of T cells balance.

    65+
    0.8–6.17 ratio

  • CD19+ B Cells, absolute

    How many B cells are in a microliter of blood. B cells are the white blood cells that grow into antibody-making cells.

    16+
    12–645 cells/µL

  • CD19+ B Cells, percent

    The share of your lymphocytes that are B cells. B cells are the white blood cells that grow into antibody-making cells.

    16+
    3–25 % of lymphocytes

  • CD16+/CD56+ NK Cells, absolute

    How many natural killer (NK) cells are in a microliter of blood. NK cells are white blood cells that help the body handle viruses and damaged cells.

    16+
    24–406 cells/µL

  • CD16+/CD56+ NK Cells, percent

    The share of your lymphocytes that are natural killer (NK) cells. NK cells are white blood cells that help the body handle viruses and damaged cells.

    16+
    1–19 % of lymphocytes

  • Lymphocytes (Absolute)

    The actual number of lymphocytes, immune cells that help fight viruses and remember germs, in a given amount of blood.

    13+
    0.7–3.1 x10³/µL
