At what point does the RBC become dangerous?

RBC 6.00 HIGH 4.14-5.80 x10E6/uL

Got this result on my test, my hemacrit is good, 50.2

I feel ok, my BP is only slightly elevated, I feel a little warm, I've only got 1.5 weeks left on this run, if I'm not in the dangerzone I'm just going to ride this out, if I'm close to danger zone I'm gonna go bleed :-)

My doc gave my RBC by %, this lab is giving it to me by the measurement above so I'm not sure how bad is bad with this measurement.
