Michaela is an athlete who has been training for several years only in Denver. She had an annual physical, and the doctor read her hematocrit as 59%. What could this reading potentially tell the doctor?

She either trained recently in an area with a high elevation, participated in blood doping, or has polycythemia vera.

Step-by-step explanation:

Michaela has a hematocrit value of 59%, which is well above the normal range, according to research that has found that athletes reduce hematocrit levels in the form of sports anemia.

This sports anemia is caused by increasing plasma volume into RBCs and increasing the total mass of hemoglobin.

But Michella has a significant increase in hematocrit rather than the normal range.

so hematocrit value suggest blood dopping which has resultted into increased hematocrit level
