Yes: Pt, ptt, inr and bleeding time have no role in the diagnosis of p. Vera. If you're eighteen years old, i'd look hard for a different cause if you are actually significantly polycythemic. There are plenty of really fit young men whose hemoglobin is a bit higher than the reference range -- athleticism to odd hemoglobin genes to something in your "gym health drink" you don't know about. Good luck.
