Question about some blood work

Just had some done and this is interesting to me:


WBC [4.5-11.0] 6.2
RBC [4.70-6.10] 5.62
HGB [13.5-17.5] 15.6
HCT [41.0-52.0] 45.7
MCV [80.0-100.0] 81.3
MCH [27.0-34.0] 27.8

As you can see I'm normal in everything, but only barely in MCV and MCH. From what google tells me it could be an iron deficiency. But if that's true wouldn't everything else show that?

Only medicine I'm on is Imuran and I don't see any blood in my stool.

I was extremely low in iron for years, never saw blood in my stool. Finally switched to a new GI and had 6 IV infusions and my levels are up and on the higher range of normal now. Even with my emergency surgery and ileostomy, my levels are still good. Makes me think my diseased colon was the problem in more ways than I thought.
