MCV

What This Marker Means

MCV measures the average size of your red blood cells. Elevated MCV often points to deficiencies in B12, folate, or B1. Low MCV suggests iron deficiency or chronic disease.

How Alcohol Affects This Marker

Alcohol frequently raises MCV due to nutrient depletion and bone marrow stress. MCV is one of the earliest markers to change in chronic drinkers, even before liver enzymes rise.

How to Discuss With Your Doctor

Ask if your MCV suggests nutrient deficiency or alcohol-related changes. If high, discuss testing B12, folate, and thiamine for deeper evaluation.
