On my most recent labs:
Hemoglobin: 15.5 g/dL (normal)
Hematocrit: 45.5% (normal)
MCV: 82.0 fL (kinda low, but still in the normal range)
RDW: 14.6% (high)
B12: 1127 pg/mL (high)
When RDW is high and MCV is low-normal this, apparently, indicates vitamin B12 or folate deficiency in the body, or the beginning stages of iron deficiency anemia.
[1] Since my B12 is high that rules out a B12 deficiency, and since my hemoglobin and hematocrit are normal that rules out iron deficiency anemia. Combined with the fact that I've had a gastrectomy, which increases my risk of folate deficiency, it's likely I am deficient in folate.
Here is one study I found that stated: "RBC folate was directly associated with delayed recall (P = 0.007) scores.". That's a very strong p-value.
