# Hemoglobin

> Hemoglobin is measured with a standard blood draw; no fasting is needed. A typical reference range is 13.5 – 17.5 g/dL (male, age 18+; more bands below). At TestWell it's $21.99 all-in as CBC with Differential, results in 1–3 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

Also known as: hemoglobin, hgb, hb.

## What does Hemoglobin measure?

The protein in red blood cells that carries oxygen from your lungs to the rest of your body.

## What is the normal range for Hemoglobin?

| Population | Reference range |
| --- | --- |
| Male, age 18+ | 13.5 – 17.5 g/dL |
| Female, age 18+ | 12.0 – 15.5 g/dL |

Reference intervals differ slightly between labs; the range printed on your report is the one to interpret against. Ranges are usually set so 95% of healthy people fall inside them.

## What does a high Hemoglobin mean?

Often reflects dehydration, smoking, or living at high altitude. In rare cases it can signal a blood disorder.

## What does a low Hemoglobin mean?

Commonly associated with anemia from iron deficiency, blood loss, chronic disease, or certain vitamin deficiencies.
