abstract = "Previous research suggests that point-of-care (POCT) determination of glycated hemoglobin (HbA1c) is a diagnostic test that can be an adequate alternative to measuring HbA1c in the laboratory. The main goal of this study was to examine the analytical characteristics of the novel INCLIX POCT method for HbA1c determination in order to test its performance before introducing this method into routine use. HbA1c is measured in a duplicate in 44 EDTA blood samples parallel on INCLIX POCT device (Sugitech, Inc.) and using automated turbidimetric immunoinhibition test on Olympus AU400 (Beckman Coulter). The within run imprecision was 7.58%, between runs imprecision was 6.63% and 6.22%, and day-to-day imprecision was 8.80% and 7.51%. Total laboratory imprecision was in agreement with those stated by the manufacturer. A statistically significant Pearson correlation coefficient was calculated (r = 0.871, P < 0.01; linear R2 = 0.757). Using Deming regression analysis, the following equation was obtained: y = - 1.80 + 1.304x. Our results indicate statistically significant correlation, linear relationship, and a significant degree of compatibility between the two analyzed methods. However, the negative bias of the HbA1c values determined on the POCT analyzer compared to the Olympus AU400 was confirmed, highlighting the need to standardize the INCLIX method., Prethodna istraživanja sugerišu da je „point-of-care“ metoda (POCT) za određivanje glikoziliranog hemoglobina (HbA1c) dijagnostički test koji može biti adekvatna alternativa merenju HbA1c u laboratoriji. Glavni cilj ovog istraživanja bio je da se ispitaju analitičke karakteristike nove INCLIX POCT metode za određivanje HbA1c kako bi se testirale karakteristike izvođenja pre uvođenja ove metode u rutinsku upotrebu. HbA1c je meren u duplikatu u 44 uzorka EDTA krvi paralelno na INCLIX POCT uređaju (Sugitech, Inc.) i automatskim turbidimetrijskim imunoinhibicijskim testom na Olympus AU400 biohemijskom analizatoru (Beckman Coulter). Nepreciznost u seriji bila je 7,58%, nepreciznost između serija bila je 6,63% i 6,22%, a nepreciznost iz dana u dan bila je 8,80% i 7,51%. Ukupna laboratorijska nepreciznost bila je u slaganju sa podacima koje je naveo proizvođač. Izračunat je statistički značajan Pearsonov koeficijent korelacije (r = 0,871, P < 0,01; linearni R2 = 0,757). Demingovom regresionom analizom dobijena je sledeća jednačina: y = -1,80 + 1,304x. Naši rezultati ukazuju na statistički značajnu korelaciju, linearnu povezanost i značajan stepen kompatibilnosti između dve analizirane metode. Međutim, potvrđen je negativan bias vrednosti HbA1c određenih na POCT analizatoru u odnosu na Olympus AU400, što ističe potrebu za standardizacijom INCLIX metode.",
