Answered by Dr. 🩺 HemoglobinExpert
A 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. This test is often part of a routine blood test called a complete blood count (CBC).
Key Uses of Hemoglobin Test:
- Diagnose Anemia: Low hemoglobin levels may indicate anemia.
- Monitor Chronic Conditions: It helps track conditions like kidney disease or diabetes.
- Evaluate Overall Health: It’s often included in general health checkups.
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 hemoglobin levels are abnormal, your doctor may recommend further tests to determine the cause.
