Can you be anaemic if rbc test is normal but hemoglobin is borderline low, mcv is a little high & mchc is low?

Anemia: Anemia is defined by a hemoglobin or hematocrit below "normal" Normal is specific to age and sex. Borderline low is still normal. High MCV could indicate folate (folic acid) or B12 deficiency, but this is not supported by low MCHC which might be seen with iron deficiency (which would actually cause the MCV to be low). All in all this then appears to be a normal variant - consider repeating in a few months.
