I am a 63 year old man and Just got my CBC test results back.They are as follows: RBC = 4.35, Hemoglobin = 11.3, Hematocrit = 35.2, MCV = 81, Platelet Count = 327. Last year all was normal. Are these numbers bad, and do they warrent doing a endoscopy to check for stomach bleeding. I would have thought the doctor would have done stool samples first.
