I am a 46 year old male. For over 7 years I have had low levels of MCV (78) and MCH (25) but all my other blood levels are normal including iron, B12, RBC, hemoglobin, hematocrit , MCHC, RDW, WBC, platelets, MPV, differential WBC s, thyroid and liver function. What does this mean in terms of possible disorders? (I also have sleep apnea , EBV, permanent sinus inflammation and off-and-on bouts of fatigue and general muscle pain.)
