Understanding MCH: Normal vs Optimal Ranges

?What is MCH?

MCH (mean corpuscular haemoglobin) is the average amount of haemoglobin per red blood cell. It parallels MCV — low MCH (hypochromic cells) is seen in iron deficiency and thalassaemia; high MCH (hyperchromic cells) in megaloblastic anaemia from B12 or folate deficiency.

!Why It Matters

MCH provides complementary information to MCV in classifying anaemia type. When low alongside MCV, it strongly suggests iron deficiency or thalassaemia and should prompt further evaluation.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.
