Now that is interesting!! I need to check into this more. My MCH was high for years except I was never sure what MCH was. I thought it was one of those lab values that nobody cared about. I took prednisone for years so maybe this explains why my MCH was always high.

Sometimes I was mildly anemic but I didn't worry about that either. My doctor said it was likely the result of chronic systemic inflammation.

I have been off prednisone for 2 years. My CBC labs are mostly all normal now. My MCH is still slightly high sometimes but to me it seems like my "normal" high MCH.
