First off I know the importance of donating blood and that donating will bring the count down. Is it not beneficial to have a slightly elevated RBC count while on? Reference range is 4.14-5.80. Blood pressure is good and the rest of the blood panel is in range (besides test) which is elevated. Is 6.03 RBC count too high? I feel great and my endurance is fantastic. Is there a specific number that when reached donation is necessary?
