The 10 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.

  • Albumin

    The main protein in blood plasma. Made by the liver, it keeps fluid inside your blood vessels and carries many substances.

    Adults
    3.5–5 g/dL
  • Creatinine

    Creatinine is a muscle waste product that your kidneys filter out, so the level in your blood is one of the main tools for checking kidney function.

    Men, 15+
    0.74–1.35 mg/dL
    Women, 16+
    0.59–1.04 mg/dL
  • Glucose

    Glucose is the sugar in your blood and your body's main fuel. This test shows how much is there at the moment the sample is drawn.

    Adults
    70–99 mg/dL
  • C-Reactive Protein (CRP, incl. hs-CRP)

    A protein your liver makes when the body has inflammation. Standard CRP helps check for infection or injury, and hs-CRP is used in heart-risk checks.

    Adults
    0–5 mg/L
  • 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 %
  • 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
  • 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 %
  • Alkaline Phosphatase (ALP)

    An enzyme made mostly in your liver, bile ducts and bones. Its blood level gives clues about those tissues.

    Men, 19+
    40–129 U/L
    Women, 17+
    35–104 U/L
  • 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
  • PhenoAge (Phenotypic Age)

    A research score that combines nine routine blood tests and your age into the age your body's chemistry most resembles.
