A1C as a Diagnostic Tool for Diabetes

Use of glycosylated hemoglobin (A1C) as a diagnostic tool for prediabetes and Type 2 daibetes In the past, diagnosis of diabetes was usually done by using plasma glucose test either using the fasting plasma glucose (FPG) or the plasma glucose (2-h PG) value after a 75-g oral glucose tolerance test (OGIT 4) (American Diabetes Association, 2014). However, a recent study in the medical field has discovered a third alternative for diagnosing the two types of diabetes. The third alternative involves the use Glycosylated hemoglobin, which was discovered by the International Expert Committee (threshold>6.5%). The test involves removing a small amount of blood from a patient suspected to have diabetes.
