Hemoglobin

Hemoglobin measures the oxygen-carrying protein inside red blood cells and is one part of a complete blood count.

SomaZeus display band

For care decisions, use the interval printed by the reporting lab and ask your clinician. Labs, assay methods, and individual context vary; the numbers below are SomaZeus display guidance.

Male: 13.5–17.5 g/dL
Female: 12–15.5 g/dL

Watch points

Watch point 1: at or above 19 g/dL
Watch point 2: at or above 18 g/dL
Watch point 3: at or above 17 g/dL

SomaZeus uses the same watch points for men and women in this display.

Why hard-training athletes watch it

Hemoglobin may change alongside hematocrit and red blood cell count, but the pattern cannot identify a cause without clinician interpretation and individual context.

When to retest

Ask your clinician whether and when a repeat is appropriate and which related blood-count values should be reviewed with it.

Talk to your clinician

Bring hemoglobin, hematocrit, red blood cell count, symptoms, prior results, and the reporting lab interval to your clinician together.
