I'm 24 yr old male. No history of smoking and drinking. Done routine Check up on 2022 dec and hb levels were 18. Doctors ordered phlebotomy thrice a week once. Also jak 2 test was ordered. Test results were negative. Again after one month the haemoglobin had increased. Doctor's ordered bma and samples were sent for next generation sequencing. Again, the test results were negative and there were no clinical findings. So is it anything to worry? Should CYTOGENIC testing done for polycythaemia vera, if next generation sequencing is already showing no clinical findings. Hoping for a reply.
