Re: Blood values - iron def. anemia or something else?

I have been following up with a hematologist - she seems to think it's classic iron deficiency. I just need a lot of iron for some reason, even though my periods are very light. I do respond really well to the iron... but I'm still a bit puzzled by my latest results:

hgb: 13.3
hct: 36.5
platelet: 162
mcv: 89
rbc: 4.12
mch: 32
mchc: 36.4 (high)
rdw: 17.0
mpv: 14.1(i think this is high, but latest test doesn't have range)
% saturation: 17% (low)
ferretin: 27

Anyway, I'm wondering what is the significance of high mchc and mpv. I didn't get to ask my hematologist because she just handed me the labwork on my way out! Any suggestions are appreciated - I still think something else might be going on since I don't think it's normal to need so much iron.
