What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

What could cause low MCV and high RDW but normal MCH, hemoglobin, and hematocrit for over a year?

How low?: Reference ranges are set so that several percent of healthy folks fall outside on either end. If your peripheral smear is unremarkable and the MCV above 70, I'd forget the whole thing. My RDW is always high from donating blood. There are some variants of thalassemia minor that will produce this and puzzle people over a lifetime, though MCH is usually lowish. ...Read more

Blood test result show high packed cell volume ,high RBC,  high WBC and high Neutrophil count what does it mean ? With Hand Burning and oral thrush.

By itself, nothing: You're a young man and your somewhat high Hct may simply be you -- reference ranges are set so that several percent of folks fall outside on either end. Same for white count. The oral thrush, if proven, calls for a check for a few illnesses; the hands, a neuropathy workup perhaps. Labs are meaningful only in the context of clinical fnidings. Your physician owes you a full explanation. ...Read more

My dads CBC range: RBC 3.95,haemoglobin 11.9, packed cell volume 34.9.others are all in range.he is 54yrs.is this a serious concern.what should he do!

Fecal occult blood: For an otherwise healthy man hemoglobin of 11.9 is lower than expected and occult blood loss needs to be excluded. It would be prudent to exclude blood loss in the GI tract. His doctor may start with testing for blood in the stool and go from there. The finding should not be ignored. ...Read more

Inflammation: You are anemic and have inflammation. Check 25-oh vit d level. Anemia could be due to iron deficiency if having heavy periods.

Labs, hematocrit high 46.9, MCHC low at 31.9 and red blood cell high at 5.16. Had labs done myself. What could cause this. Anxious something's wrong!

Try HealthTap PRIME: Lab results usually are numbers, and numbers are just numbers, with little meaning unless a doctor takes in the whole picture of what's going on with his patient. "Creating patient anxiety" is one of the arguments against people doing their own lab tests. One can try HealthTap PRIME for a virtual consultation, in which a doctor can ask questions and look over the lab results, to explain them. ...Read more
