What is Hemoglobin A primarily associated with in adults?

Hemoglobin A (HbA) is the predominant form of hemoglobin found in adults, making up about 95% of total hemoglobin in healthy individuals. It is responsible for the transportation of oxygen from the lungs to the tissues and helps in delivering carbon dioxide back to the lungs for exhalation.

In healthy adults, normal levels of Hemoglobin A are indeed above 95%, which signifies proper oxygen-carrying capacity and functioning of red blood cells. This normal range is critical for diagnosing various blood conditions, as deviations from this percentage can indicate disorders such as thalassemia or sickle cell disease.

Understanding the normal reference range for Hemoglobin A is fundamental in hematology, as it serves as a baseline for identifying hematologic abnormalities in patients.
