More Hemoglobin Blood Test Information
The hemoglobin test, sometimes known as a hemoglobin lab test, an Hgb blood test, or an Hb test, measures the hemoglobin blood level.
Hemoglobin is a common protein in the body that contains iron and plays a vital role in the body. Making up a good part of a red blood cell, hemoglobin picks up oxygen in the lungs and transports it in the bloodstream to cells and tissues. At the tissue level, hemoglobin then releases oxygen for tissue use. Each hemoglobin molecule can bind up to four oxygen molecules at one time.
The hemoglobin test is an important component of the CBC test. Hemoglobin testing is also performed as a broad screening test for anemia. Carbon monoxide bind hemoglobin molecules much stronger than oxygen which results in carbon monoxide poisoning if one is exposed to high levels of carbon monoxide.
