The 4 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.

  • Carboxyhemoglobin (COHb)

    The share of your hemoglobin that is bound to carbon monoxide instead of oxygen. It shows recent carbon monoxide exposure, including from smoking.

    Adults
    0–2 %

  • Methemoglobin (MetHb)

    The share of your hemoglobin in a form that can't carry oxygen well. Labs usually report up to about 1.5%, and higher levels can cause blue-gray skin.

    Adults
    0–1.5 %

  • Oxygen Saturation, Arterial (SaO2)

    How much of the hemoglobin in your arterial blood is carrying oxygen, measured directly from a blood sample. Finger pulse oximeters estimate this same number.

    Adults
    95–100 %

  • 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
