What does HGB stand for in a hematology context?

In a hematology context, HGB stands for Hemoglobin. Hemoglobin is a crucial protein found in red blood cells that is responsible for transporting oxygen from the lungs to various tissues throughout the body and returning carbon dioxide from the tissues back to the lungs.

Understanding hemoglobin’s role is essential for interpreting various hematological tests, as it is a key marker used in diagnosing and monitoring conditions such as anemia, respiratory disorders, and other blood-related conditions.

The other options, while they contain terms related to hematology, do not accurately represent what HGB signifies. Hemostasis Globulin, Hematology Granulocyte, and Hematocrit Globulin do not reflect established terminology in the field of hematology, making them incorrect in this context.
