Mean Corpuscular Hemoglobin (MCH)

MCH calculates the average amount of hemoglobin contained within a single red blood cell. As part of a Complete Blood Picture (CBP), it is a calculated index (Hb/RBC count). It is essential for the morphological classification of anemias. It tells the clinician whether the red cells are 'hypochromic' (pale, lacking hemoglobin) or 'normochromic'. This helps narrow down the cause of anemia before more expensive tests (like ferritin or B12) are ordered.

Why Context Matters
MCH can be falsely elevated by hyperlipidemia (high fats in blood) or high levels of bilirubin, as these interfere with the automated spectrophotometric measurement of hemoglobin. If MCH is high but the patient doesn't fit the profile for macrocytic anemia, a slide review (peripheral smear) is necessary.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
