I am 56, 64 inches and 110 pounds.  Blood test consistently show elevated MVC and MCH 99.6 and 34.1 respectively.  Mchc is normal at 10.5.Ruled out hypothyroidism, B12 and folic acid deficiency.  WBC is 3.9 and RBC is 3.75.  Would you recommend a bone marrow biopsy?  Thank you,
Hi, Thanks for asking. Looking at the hematological report and clinical features, I am of the following opinion.:1. 99.6 is normal MCV (80-100) and MCH, MCHC are also near normal limits.2. Good to know that you have no other deficiency.3. WBC count is mildly reduced. Platelet count if reduced also, might suggest bone marrow problems secondary to malnutrition.4. Your weight appears too low. You need to improve your diet to improve over all values. Bone marrow biopsy not necessary now. Improve nutrition and followup tests after 1 month. Any further queries, happy to help again.
