Mean Corpuscular Haemoglobin (MCH) is the amount of haemoglobin per red blood cell.  MCHC is an estimate of the concentration of haemoglobin in a  given number of packed red blood cells.

MCHC = (Hb[note]Hb:Haemoglobin[/note] ÷ HcT[note] HcT: haemotocrit or packed cell volume[/note]) x 100

Normal in children is 32-34% (adults 28-36%) depending on the lab
