Recent blood test shows low indirect bilirubin (.08)+increased blood volume (99.7)+increased hematocrit (47.2)+high WBC (14, 200). Huh?

Uncertain. The WBC is definitely high, but the HCT and MCV are borderline, and thus of uncertain significance. If truly elevated, the HCT could point to a primary or secondary polycythemia, an increase in the number of red blood cells. But this could also reflect mild dehydration, and given the borderline degree could be nothing. The high WBC is real. If you have no symptoms I would just repeat in 1mo.
