<s>[INST] I had a Red Blood count and part of the break down : Hgb, hematocrit - I know. What is MCH?I know from a previous blood test - I am anemic, and we had ordered a second test to see if any improvement. Should I ask a pathologist instead of a General Practioner? [/INST] Hi, dear. I have gone through your question. I can understand your concern. MCH is mean corpuscles hemoglobin. Its normal value is 27 to 31 pg. It is decreased In iron deficiency anemia. If you have gone through repeat test for anemia then consult your physician and ask for improvement and then take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health. </s>
