Blood count

MCV

What it means

Mean Corpuscular Volume — the average size of your red blood cells. Small (low MCV) often points to iron-deficiency anaemia; large (high MCV) often points to vitamin B12 or folate deficiency.

Typical normal range

83–101 fL

Reference ranges vary by lab, age, sex, and pregnancy. Always check the range on your own report.
