The 6 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.

  • Troponin I (Cardiac, incl. High-Sensitivity)

    A protein released when heart muscle cells are damaged. Doctors use it to find out whether the heart muscle has been injured, most often when someone has chest pain.

    Men, 18+
    up to 35 ng/L
    Women, 18+
    up to 17 ng/L

  • Troponin T (Cardiac, incl. High-Sensitivity)

    A protein released when heart muscle cells are damaged. Doctors use it to find out whether the heart muscle has been injured, most often when someone has chest pain.

    Men, 18+
    up to 22 ng/L
    Women, 18+
    up to 14 ng/L

  • CK-MB

    A heart-muscle form of the enzyme creatine kinase. It was long used to look for heart muscle injury, and troponin has now mostly replaced it.

    Adults
    0–5 ng/mL

  • Creatine Kinase (CK), Total

    An enzyme found mostly in muscle. It leaks into the blood when muscle is strained or injured, so hard exercise is a common reason for a high result.

    Men, 19–49
    26–366 U/L
    Women, 19–49
    20–239 U/L
    Men, 50–59
    23–325 U/L
    Women, 50–59
    21–240 U/L

  • BNP (B-Type Natriuretic Peptide)

    A hormone your heart releases when it is stretched. It helps clinicians judge whether symptoms like shortness of breath could be from heart failure.

    Adults
    up to 100 pg/mL

  • NT-proBNP (N-Terminal pro-B-Type Natriuretic Peptide)

    A protein fragment your heart releases when it is under strain. It helps clinicians judge whether symptoms like breathlessness could come from heart failure.

    18–74
    up to 125 pg/mL
    75+
    up to 450 pg/mL
