Mean corpuscular hemoglobin (MCH)
Average hemoglobin amount per red blood cell; useful for classifying anemias.
Mean Corpuscular Hemoglobin (MCH) Biomarker Test
MCH is the average amount of hemoglobin in each red blood cell, reported in picograms (pg). Hemoglobin is the protein that binds oxygen in the lungs and delivers it to tissues. MCH is calculated from the hemoglobin level and red blood cell count in a standard complete blood count (CBC). Lower MCH reflects hypochromia—cells with less hemoglobin—often linked to iron deficiency or thalassemia traits.Higher MCH reflects macrocytosis—larger cells with more hemoglobin—often linked to B12 or folate deficiency. Interpreted alongside MCV (cell size), MCHC (hemoglobin concentration), RDW (size variation), hemoglobin, and hematocrit, MCH helps pinpoint root causes of anemia and oxygen delivery issues.
