I'm a non smoker and non drinker. I took a cbc routine test and my hbg was 18.5 about 20 days back. So I was given aspirin 75 mg daily use and also did course of phlebotomy 3 times for one week. Also my erythropoietin test result was 11.3 and my jak 2 results was negative. So doctor stopped my aspirin and after all that phlebotomy course my hbg count was 14.8 But the issue is after just 8 days after my phlebotomy was stopped, my hbg is 15.5 already. Increased 0.7 just 8 days. What can be the issue? Am I having any issues in my blood?
