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. This test is often part of a routine blood test called a complete blood count (CBC).
Key Uses of a 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 used to check for infections, blood disorders, or nutritional deficiencies.
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 testing to determine the cause.
