What is Mean Corpuscular Hemoglobin (MCH)?
Mean Corpuscular Hemoglobin is measured as part of a complete blood count (cbc) panel. The amount of hemoglobin in each red blood cell is normal.
What does a high Mean Corpuscular Hemoglobin mean?
Each red blood cell contains more hemoglobin than normal, often accompanying macrocytic anemia caused by B12/folate deficiency.
What does a low Mean Corpuscular Hemoglobin mean?
Each red blood cell contains less hemoglobin than normal (hypochromic). This strongly points toward iron deficiency, especially when MCV is also low.
