Journal Title: Medpulse International Journal of Community Medicine - Year 2018, Vol 8, Issue 1
Abstract
Background: Prediabetes is a condition having higher than normal blood glucose but not high enough for a diagnosis of diabetes.If we can detect it early, we can prevent diabetes to a great extent. The higher than normal level of HbA1c indicates future risk of developing diabetes. Thus we have conducted this study to explore utility of HbA1c as a screening test for prediabetes. Methodology: It was a cross sectional study, conducted in a private clinic ran exclusively for diabetic patients in Latur, Maharashtra. All patients visiting OPD from 1st September 2016 to 31st August 2017 were enrolled in study. After doing the clinical examination of all study subjects, the investigations of Fasting blood sugar, Post meal blood sugar and HbA1c were done for all of them. The patients falling under diabetic range were excluded from the study. The data for remaining patients was analyzed to test sensitivity and specificity of HbA1c level as compared with fasting and post meal sugar levels. Observations: Total 822 patients were enrolled in the study period. Among them, 710 were diabetic and hence excluded from the study. HbA1c level was 81.25% sensitive and 35.00% specific as compared to fasting blood sugar for diagnosing pre diabetes while it was 80.85.% sensitive and 38.46% specific as compared to postmeal blood sugar. Conclusion: HbA1c is a good screening test for prediabetes.
