Abnormal mean corpuscular hemoglobin concentration (HP:0025546)help
Term ID: 25546
Name: Abnormal mean corpuscular hemoglobin concentration
Synonym: Abnormal MCH; Abnormal MCHC; Abnormal mean corpuscular haemoglobin; Abnormal mean corpuscular haemoglobin concentration; Abnormal mean corpuscular Hb concentration
Definition: A deviation from the normal range of the average amount of hemoglobin per red blood cell (27 to 31 picograms/cell). A reduced mean corpuscular hemoglobin (MCH) may indicate a hypochromic anemia, but the MCH may be normal if both the total hemoglobin and the red blood cell count are reduced.
