Hemoglobin A1C determination by point-of-care testing: its correlation to standard method

The hemoglobin A1C (HbA1C) is the useful test for following up of glycemic control of the diabetic patient. Due to the present advance in point-of-care testing (POCT) technology, the new POCT for determination of HbA1C is available. Here, the author performs a laboratory comparative study between the new POCT tool (DCA) and classical tool (COBAS) for analysis of HbA1C level. This study is the second confirmation study in Thailand performed in the new setting adding to the previous author's report. The results show that there is a good correlation between two techniques and the error of the POCT tool is within acceptable limit.
