diabetes test

Glycohemoglobin T he glycohemoglobin test was developed in the late 1970's. Other names that have been used to describe the same test are glycosylated hemoglobin , and hemoglobin A1c . This test gives information about your average blood sugar level during the past two or three months. The normal values for this test vary depending upon the lab, and you must look at the "normal range" or "reference range" that the lab uses to make sense of your result (1) . If your glycohemoglobin value is higher than the normal range, then we know that your average blood sugar has been elevated during the past two months. More importantly, if your recent glycohemoglobin is lower than your previous value, then we know that you are now doing better than before!
