An MCV greater than 89.9 is common finding in B12 deficicency. Look for other indicator of B12 deficiency such as MCHC and RDW. If these levels are elevated above normal. Methylmalonic acid and homocysteine levels are more sensitive B12 status tests. If suspect B12 deficiency, 1000 mcg of B12 injection weekly for 4 weeks and retest. ................
