MCH

What This Marker Means

MCH measures the average amount of hemoglobin inside red blood cells. Low MCH suggests iron deficiency, while high MCH can occur with B-vitamin deficiencies.

How Alcohol Affects This Marker

Alcohol-related nutritional deficits—particularly B12 and folate—can increase MCH. Heavy drinking can impair hemoglobin synthesis, altering MCH levels.

How to Discuss With Your Doctor

Ask whether your MCH changes indicate nutrient deficiency or early anemia. Mention your alcohol intake to help interpret results accurately.
