DIABETES.

Objectives: The objective of this study was to evaluate the variations in HbA1c on repetition over a span of about two weeks. Period: June 2015 to May 2016. Setting: Department of pathology, Continental Medical College Lahore, attached with Ch. Rehmat Ali Memorial Trust Teaching Hospital. Method: A total of 60 newly diagnosed or with no apparent diabetic complications were included in this study. Venous blood repeated samples were obtained for evaluation of HbA1c. Results: The result of our study show that in 65% of patients the repeated values were lower than the initial values, 25% were higher and 10% were below the diagnostic threshold. So it is indicated that HbA1c values vary over a span of time and repeated tests values should be considered for borderline patients. Conclusion: It is concluded from this study that values of HbA1c do differ on retest. Therefore, physicians should understand and not be confused with a little bit variations in values. It is recommended to repeat the test for newly diagnosed and borderline value patients to reach a final conclusion about diagnosis. It is also recommended that a separate study should be conducted to evaluate the cause/mechanism behind variations in HbA1c over a short period of time in our settings. [ABSTRACT FROM AUTHOR]
