I have had (slightly in my opinion) elevated  blood counts a few times. My primary care physician has referred me to a hematologist regarding possible Polycythemia. I am paying out of pocket and the consult would be about $400 so I am hesitant, but if is is vital I will do it. My number don't seem that high to me. I am a 53 year old white male. Here are some of the numbers: hemoglobin  17.6 GM/CMM, rI have had (slightly) elevated hemoglobin and my primary care physician has referred me ted blood count 5.3 M/CMM (normal range), Hematocrit 50.0% (within range), white blood count 7.6 (within range) all other measurements they took are within range (No POS was done) except EOS0.9%, ABS MONO 10.7%, BASO 1.2%, MEAN Corpuscular HGB33.3 UUG. (which may not be relevant?) I have had elevated measurements on few prior tests. Does it seem that important/ necessary to go to a specialist?
