Is the above explanation accurate?  I thought hemoglobin was the protein in 
the red blood cells that carries oxygen and that when BG levels are high, 
sugar attaches to the hemoglobin.  Even without a high, the red blood cell 
would still have hemoglobin.

Please excuse me for sounding nit-picky, but I'm just wanting to know if the 
hemoglobin actually increases with high BGs or just the amount of sugar 
attached to the hemoglobin?
