Re: Slightly elevated MCV and MCH, does this mean anything?
Yes, an elevated MCV does indicate either a B12 or folic acid deficiency. At 430, that's sorta iffy. I started having terrible B12 deficiency symptoms when my B12 levels hit 360 - that's not that much lower than yours. I felt like death warmed over.
You didn't say what your hemoglobin levels are. That's what my hema goes by, not really as much the RBC. Anyway for me, it doesn't matter what my RBC count is, if my B12 levels are iffy, I have no energy, no motivation, headaches, just awful.
Anyway, I started getting B12 shots, and once my B12 levels hit 800, I started feeling remarkably better. Maybe you can talk your dr. into getting the shots.
