Comparing the Efficacy of Samsung LABGEO PT10 and Bio-Rad Variant II Turbo for HbA1c Measurement in Three Types of Blood Samples

ABSTRACT

BACKGROUND: Hemoglobin A1c (HbA1c) is a good marker for monitoring glycemic control. The Samsung LABGEO PT10 HbA1c test (Samsung Electronics, Korea) was developed as a point-of-care testing approach. This study evaluated the levels of HbA1c in three different types of blood specimens using two different methods. METHODS: We used correlation analyses to compare the results obtained using Samsung LABGEO PT10 and Bio-Rad Variant II Turbo (Bio-Rad Laboratories, USA) to determine the levels of HbA1c in three different types of blood samples: capillary blood, EDTA whole blood, and lithium (Li)-heparin whole blood. RESULTS: The correlation coefficient for the level of HbA1c in capillary blood based on LABGEO PT10 vs. that in EDTA whole blood based on the Variant II Turbo was r=0.9619; that in capillary blood based on LABGEO PT10 vs. that in Li-heparin whole blood based on the Variant II Turbo was r=0.9619; that in capillary blood vs. that in EDTA whole blood based on the LABGEO PT10 was r=0.9697; that in capillary blood vs. that in Li-heparin whole blood based on the LABGEO PT10 was r=0.9724; and that in EDTA whole blood vs. that in Li-heparin whole blood based on the LABGEO PT10 was r=0.9730. CONCLUSIONS: The LABGEO PT10 was suitable for analyzing HbA1c. The results for the measurement of HbA1c levels in capillary blood were comparable to that in the whole blood samples. Additionally, LABGEO PT10 can be used for patients who are unable to take venipuncture.
