CBC With Differential/Platelet

The 24 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.

• White Blood Cell Count

  The total number of white blood cells, the immune cells that fight infection, in a small sample of your blood.

  Adults

  3.8–10.8 ×10³/µL

• Red Blood Cell Count

  The number of red blood cells in a sample of your blood. These cells carry oxygen from your lungs to the rest of your body.

  Men, 18+

  4.3–5.7 ×10⁶/µL

  Women, 18+

  3.9–5 ×10⁶/µL

• Hemoglobin

  The oxygen-carrying protein in your red blood cells. It is the main number used to check for anemia.

  Men, 16+

  13–17.7 g/dL

  Women, 16+

  11.1–15.9 g/dL

• Hematocrit

  The share of your blood made up of red blood cells, shown as a percent. It usually moves together with hemoglobin.

  Men, 13+

  37.5–51 %

  Women, 13+

  34–46.6 %

• Mean Corpuscular Volume (MCV)

  The average size of your red blood cells. It helps show whether they run smaller or larger than usual.

  18+

  80–100 fL

• Mean Corpuscular Hemoglobin (MCH)

  How much hemoglobin, on average, each of your red blood cells carries.

  18+

  27–33 pg

• Mean Corpuscular Hemoglobin Concentration (MCHC)

  How concentrated the hemoglobin is inside your red blood cells, which shows how pale or dense they are.

  18+

  32–36 g/dL

• Red Cell Distribution Width (RDW-CV)

  How much your red blood cells vary in size. A higher number means a wider mix of small and large cells.

  Adults

  11.7–15.4 %

• Platelet Count

  The number of platelets, the small blood cells that help your blood clot, in a sample of your blood.

  Adults

  150–450 ×10³/µL

• Mean Platelet Volume (MPV)

  The average size of your platelets, the small blood cells that help your blood clot.

  Adults

  7.2–12.3 fL

• Neutrophils (Percent)

  The share of your white blood cells that are neutrophils. The absolute neutrophil count is usually the more useful number.

  Adults

  39.4–72.5 %

• Lymphocytes (Percent)

  The share of your white blood cells that are lymphocytes, immune cells that help fight viruses, shown as a percent.

  18+

  17.6–49.6 %

• Monocytes (Percent)

  The share of your white blood cells that are monocytes. The absolute monocyte count is usually the more useful number.

  Adults

  4.1–12.4 %

• Eosinophils (Percent)

  The share of your white blood cells that are eosinophils, a cell type involved in allergies and in fighting some parasites.

  Adults

  0.4–6.7 %

• Basophils (Percent)

  The share of your white blood cells that are basophils, the rarest white cell type, which takes part in allergic reactions.

  Adults

  0.3–1.4 %

• Immature Granulocytes (Percent)

  The share of your white blood cells that are young, not-yet-mature granulocytes. Clinicians read it with the rest of your CBC.

  18+

  0–0.9 %

• Neutrophils (Absolute)

  The number of neutrophils in a microliter of blood. Neutrophils are your most common white blood cell and a first line of defense against germs.

  13+

  1.4–7 ×10³/µL

• 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

• Monocytes (Absolute)

  The number of monocytes in a microliter of blood. Monocytes are white blood cells that clear debris and help fight infection.

  Adults

  0.1–0.9 ×10³/µL

• Eosinophils (Absolute)

  The number of eosinophils, white blood cells that take part in allergies and fight some parasites, in each microliter of your blood.

  14+

  0–0.5 ×10³/µL

• Basophils (Absolute)

  The number of basophils, the rarest white blood cell, in each microliter of your blood. Basophils take part in allergic reactions.

  18+

  0–0.2 ×10³/µL

• Immature Granulocytes (Absolute)

  The number of young white blood cells (immature granulocytes) in a microliter of blood. Most healthy adults have very few.

  18+

  0–0.1 ×10³/µL

• Nucleated Red Blood Cells (nRBC) (Percent)

  How many nucleated red blood cells are in the blood for every 100 white blood cells. Healthy people usually have none after the first weeks of life.

  0.011+

  up to 0 % (per 100 WBC)

• Nucleated Red Blood Cells (nRBC) (Absolute)

  The number of nucleated red blood cells in each microliter of blood. Healthy people usually have none after the first weeks of life.

  0.011+

  up to 0 ×10³/µL
