What Is an HGB Blood Test Used For?

The HGB blood test is often ordered as a check of overall health or during the diagnostic process if a patient complains of shortness of breath, dizziness, weakness or fatigue, according to Mayo Clinic. In addition, the HGB blood test may be used to monitor and steer treatment plans for polycythemia vera or anemia.

An HGB test measures the level of a protein in the red blood cells called hemoglobin that is responsible for carrying oxygen to tissues and organs and transporting carbon dioxide away, notes Mayo Clinic. A higher-than-normal level of HGB in the blood is often found in people who smoke, but it can also be an indicator of the presence of advanced lung disease, bone marrow disorder, drug abuse, or other conditions, notes MedicineNet.
