Hemoglobin (Hb) is the iron-containing protein in red blood cells responsible for transporting oxygen from the lungs to the rest of the body. It is the most critical component of the Hemoglobin, TC, DC, ESR & Platelet Count panel for diagnosing anemia. Hb levels determine the blood's oxygen-carrying capacity and are used to guide blood transfusion decisions and monitor chronic conditions like kidney disease or iron deficiency.

Why Context Matters
Levels can be artificially high due to dehydration (hemoconcentration) or smoking, and artificially low due to pregnancy (hemodilution) or fluid overload. Results must be interpreted alongside MCV and iron studies.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
