<s>[INST] hello Dr. i was having a skin rash when exposed to the sun and feel really really tired everyday. Is there any chance i was having Polycythemia. Ive done some blood test and my result came out with me having lots of red blood cell count and a high haemoglobin. but the doctor said i was fine. [/INST] How much hb and rbc count you have that you not said.criteria for polycythemia is fixed described by WHO. High hb high rbc count jak 2 mutation etc. So without hb and rbc anc jak 2:we cant say you have polycythemia or not. </s>
