What is the meaning of the abbreviation HGB?

The abbreviation HGB stands for hemoglobin. Hemoglobin is a crucial protein found in red blood cells that is responsible for transporting oxygen from the lungs to the rest of the body and returning carbon dioxide from the tissues back to the lungs for exhalation. It plays a significant role in maintaining proper oxygen levels in the bloodstream, which is vital for cellular metabolism and overall bodily function.

Other options do not accurately represent the common medical terminology associated with HGB. Hematologic Guide Book, Health Global Benchmark, and Hydration Gradient Balance are not recognized medical terms or standard abbreviations associated with clinical practice, and they do not convey the important physiological role that hemoglobin plays in the body. Understanding that HGB refers specifically to hemoglobin is essential for interpreting lab results and understanding patient health status in clinical settings.
