What does HGB stand for?

HGB stands for Hemoglobin. Hemoglobin is a vital protein found in red blood cells that is responsible for transporting oxygen throughout the body and facilitating the removal of carbon dioxide. Its measurement is important in clinical settings as it helps assess a patient's oxygen-carrying capacity, identify potential anemia, and monitor various health conditions. The other options, while potentially related to medical terminology, do not accurately represent the abbreviation HGB.
