| | A newer test for blood glucose - it may be very useful |
| | The editorial in the Annals of Internal Medicine advocates glycosylated hemoglobin, in part because it is "inexpensive". | | | Every one percent increase in glycosylated hemoglobin above 5 percent increased risk of heart attack or stroke by 20 percent. | | | Those men and women who had glycosylated hemoglobin levels between 5.1 percent and 6.9 percent had a consistent and progressive increase in the rate of heart attack, stroke, and death as the glycosylated hemoglobin level rose from 5 percent to 5.5 percent to 6 percent to 6.5 percent and to 7 percent. |
