According to the Appraise test that I took on October 16, my A1C was 5.2 percent. The hospital test that I took less than three weeks later on November 4 was 5.5 percent. Since my diet, weight, and exercise remained the same, I expected closer results, although they may be within the margin of error. Considering that the NGSP certified the Appraise test and not the hospital one, I know which one is more likely to be right.

Finally, we have the little matter of price. The hospital test cost me a $15 co-pay and several hours of my time. The Appraise test sells for $19.95, and we don't need a prescription to buy one. Heritage Labs gave me the first test kit. But I just ordered another one so I can check my A1C again in a couple of months on my nickel.
