Thank you, Will.
Hi for nygirl, good to hear from you.
Hey Jack just wanted to say hi!!!!!!!
An RBC of 5.7 mill/ul/cu mm would not be considered high at many labs. It is in the high part of normal. If RBC"s are truly high ,no-one here would be able to tell you why. It can be caused by a multitude of conditions,and a doctor would have to do a full clinical history and other blood tests to diagnose why.
If your doc is not concerned after it being at this level in 4 tests done in the last 2 years,I doubt you have anything to worry about either
