The HbA1c test and the blood glucose test were compared in order to diagnose type 2 diabetes and determine the best cut-off point for the HbA1c test for optimal sensitivity in the population of Mosul city (inside it and some rural areas around it). The test was performed on a group of people between the ages of 40 and 85 who came to our laboratory after being diagnosed with or without type 2 diabetes by specialists in internal medicine and endocrinology. The HbA1c and FBS analysis were carried out between January 2020 and January 2021. And, by using ROC curve, the results for 80 individuals with an average age of 56 years produced a HbA1c test with a value of 6.8 percent, a sensitivity of 94 percent, compared to the result of 126 mg/ml for FBS as a diagnostic criterion , and the optimal cutoff point for HbA1c was reached for 6.86% in diagnosing disease diabetes type 2 was given the highest Yuden index by ROC curve analysis. Conclusion: We recommend that the optimal value of Hb2 with a percentage of 6.86 percent be used as the best test in diagnosing type 2 diabetes and obtaining the best medical and health care for the Mosul population.
