Hello Dr. Rynne! After ruling out supplementary iron (Ferrous Glutamate/Vitamin C ) for anemia, my physician referred me to a hematologist . The speciialist drew several vials of blood, asked for a thorough history, etc. (to rule out unhealthy life-styles, bleeding, etc.). I have been blessed with extremely good health: kept weight wnl, ate healthy (nutrition student in college), and have had no major surgeries. All I really want to know is what these acronyms stand for in the listing of the blood analysis: MCH, MPV, MO (%), and LY (#). I have figured out the others. The lab results showed Anemia, macrocytic as the Problem. I have looked that up on-line and understand enough there. (We will be meeting to discuss these results within 2 weeks, but I m curious now). The anemia showed up during a hospital stay for pneumonia in April--in spite of having had both flu and (earlier) pneumonia vaccines. Except for pregnancies, the only other hospitalization was for a TIA at age 65--another mystery since I have had low blood pressure and have had normal ranges for cholesterol, triglycerides, blood glucose, etc. etc. It was likely due to stress following my husband s death. Since you likely may benefit from the big picture, the results were low for WBC, RBC,HGB, HTC, MPV & LY# and high for MCH and the MO%.. None were indicated as clinically significant. Although not tagged as high, the MCV was at the very top of the Range (81.0-99.0). OH! I have been on Forteo (osteoporosis) for roughly 20 of the 24 months allowed. I was put on aspirin regimen after my TIA which was later changed to Aggrenox.. Trying to keep this short but still give you enough of a profile to answer the meaning of these acronyms on the blood profile (summarized): MCH, MCHC, MO% and LY#. Thanks! Judy
