Abstract --- Prediabetes is a condition blood glucose levels are higher than normal but lower than diagnosis of diabetes mellitus. Parameters prediabetes according to the American Diabetes Association 2017, blood glucose levels ≥100 - <126 mg/dL in impaired fasting glucose, ≥ 12 mg/dL in impaired glucose tolerance and HbA1C level 5.7 - 6.4%. HbA1C test describe of the state blood glucose in the last 2-3 months. The study aimed to determine relationship of fasting blood glucose and HbA1C value in determining prediabetes. Methods of research is descriptive, using secondary data. Data collection was carried out during April to September 2018 at one of the private hospitals in East Bekasi. Total samples inclusion factor were 92 samples. The Spearman test results showed relationship is positive and weak (r = 0.230) with α = 0.05 and the linear regression test line equation yields HbA1C value = 5,430+ 0.003 (blood glucose value) + 0.005 (age) with R value 0.309 between fasting blood glucose test and HbA1C values in prediabetes. The results of this study indicate that value of fasting blood glucose affects value of HbA1C. The higher blood glucose is more Hb molecules that bind to sugar.
