Abstract

HbA1c is considered the gold standard of long-term glycemic control and is recommended as a routine test for every diabetic patient. However, its common use in clinical practice has some problems related to lack of standardization and its relative cost. Recent studies have suggested, that postprandial blood glucose could be better than a fasting sample, as a marker of diabetes control. The objective of the present study was to evaluate the relative value of plasma glucose samples at different times of the day, and easy and accessible programs for home blood and urinary glucose measurements compared with HbA1c in assessing the mean glycemic control of type 2 diabetic patients. Sixty type 2 diabetic patients were instructed to do home blood and urine glucose monitoring for two months, at the end, plasma glucose profiles were obtained. The mean of all the capillary BG measurements had the best correlation with the HbA1c (r = 0.84, p < 0.001), followed by the mean of the capillary BG measurements before breakfast and supper (r = 0.82, p < 0.001), and the 2 hr. postbreakfast plasma glucose (r = 0.79 p < 0.001). The fasting PG had a low correlation (r = 0.65, p < 0.001), but a good sensitivity to predict a fair or a poor metabolic co...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
