MCH – Mean Corpuscular Hemoglobin Unit Converter
Mean Corpuscular Hemoglobin (MCH) is a measure of the average mass of hemoglobin contained within a single red blood cell (RBC). It is one of the three primary red cell indices used to help classify the type and cause of anemia. [Image of red blood cell indices chart]
MCH is derived from the complete blood count (CBC) data using the formula: MCH (pg) = Hemoglobin (g/dL) / RBC Count (million/µL) × 10. Low MCH indicates a cell contains less hemoglobin than normal (often seen in iron deficiency), while high MCH indicates a cell contains more (often seen in macrocytic anemia). The primary unit of measure is the picogram (pg).

Clinical Context
Reference Range (Adults): Typically 27.0 – 33.0 pg.
Low MCH (< 27 pg) suggests microcytic or hypochromic anemia (small, pale cells), characteristic of iron deficiency.
High MCH (> 33 pg) suggests macrocytic anemia, characteristic of Vitamin B12 or folate deficiency.
All units are related by powers of 1000:
1 pg = 1 µµg.

Frequently Asked Questions & Tips
Yes. The obsolete micromicrogram (µµg) is numerically identical to the picogram (pg).
MCH is the mass of hemoglobin per cell, while MCHC is the concentration of hemoglobin within a given volume of packed red cells.
