Thank you for your answers, feel bit more reassured 🙂
So what does exactly the guidance material mean by “polycythemia” (i believe in newer edition its called erythrocytosis). Is it reserved for the primary polycythemia, which like Radgirl clarified is a blood cancer?
what is then the upper limit of hemaglobin and hematocrit that will get you in trouble and require more tests? Or does it wary by country and there is no universal easa guidance?
