what does hgb test for

The Hgb test, also known as the Hemoglobin test, measures the amount of hemoglobin in your blood. Hemoglobin is a protein in red blood cells that carries oxygen from your lungs to the rest of your body and returns carbon dioxide from your tissues back to your lungs.

Key Uses of the Hgb Test:

• Diagnose Anemia: Low hemoglobin levels may indicate anemia.
• Monitor Chronic Conditions: It helps track conditions like kidney disease or diabetes.
• Evaluate Overall Health: Often included in routine blood tests to assess general health.

Normal Hemoglobin Levels:

Group Normal Range (g/dL)

Adult Men 13.8–17.2
Adult Women 12.1–15.1
Children Varies by age

If your results are outside the normal range, consult your healthcare provider for further evaluation.
