hemoglobin testing

Hemoglobin testing measures the amount of hemoglobin, a protein in red blood cells that carries oxygen throughout your body. This test is commonly used to assess overall health and diagnose conditions like anemia, where there aren’t enough red blood cells or hemoglobin. The test typically involves a simple blood draw. Results can help your doctor understand how well your body is transporting oxygen, identify nutritional deficiencies, or monitor chronic diseases. Normal hemoglobin levels vary by age and sex but are crucial for maintaining energy and overall well-being.
