This is Dr Basu, Experienced Specialist.
I am here to address your concerns and provide great service.
Your RBC and hematocrit are mildly elevated but still below the concerning level ( for HCT it is upto 51 ).
Dehydration can cause false elevation of these numbers.
Hence, drinking adequate fluids will often help.
Smoking and hypoxia are other common causes.
can cause hypoxia and resultant rise.
So not concerning but should be repeated in 2-3 months or so.
Please discuss with your doctor also.
