High red blood cell/hemoglobin count -What does it mean?!

High red blood cell/hemoglobin count -What does it mean?

Hi, I'm a healthy 21 year old male. Recently, I spoke with the secretary at my doctor's office since he was busy and she let me know everything was fine but I had a slightly high red blood cell/hemoglobin count and there was nothing to worry about. I am not worried but just wondering what sort of things can cause a high RBC/Hemoglobin count? Thanks

If it was a little high, I would bet that you were a little dehydrated when the test was performed.

Hemoglobin is a concentration and as such, can fluctuate depending on the volume of blood in a person's body. So if you have a normal level of hemoglobin, but a little less water in your blood then usually, the concentration would be a little high.
