Ahh…so the hematocrit limit figure of 50 to suspect doping is 50% of the blood volume .
Correct.
Mine lives at like 0.49.
Hb in the 160s.
Ferritin in the 200s.
I think the days of using hct’s as an indication of EPO use are long gone, it was part of the original biological passport system in cycling I think, was also considered dangerous to race when above 0.50 due to the viscosity of the blood. These days they have very sensitive assays for EPO so I am not sure what the place of hct is anymore.
