Mean Corpuscular Hemoglobin (MCH)

Mean corpuscular hemoglobin (MCH) defined as the average weight of Hb per RBC. MCH is not directly measured; it is derived:

MCH = Hb/RBC count

Under normal conditions:

30 g/L = 150 g/L/5 x 1012/

Imagine drilling a hole in the wall of an RBC, extracting
all the hemoglobin (red color in schematic below) and
weighing it… that would give you the MCH
