What is hgb in a hemotology report?

HGB, or hemoglobin, is a protein found in red blood cells that carries oxygen from the lungs to the rest of the body and returns carbon dioxide for exhalation. In a hematology report, the HGB level is measured to assess the oxygen-carrying capacity of the blood. Abnormal levels can indicate various conditions, including anemia, dehydration, or blood disorders. Normal ranges vary by age and sex, making context essential for interpretation.
