Abstract:
Objective To preliminarily evaluate the performance of glucose detention reagents with three kinds of different chro-mogens and to investigate their anti-interference performance according to NCCLS document.Methods According to the protocol EP10-A2 provided by the National Committee for Clinical Laboratory Standards(NCCLS),the samples with low,middle and high level of glucose were detected by the glucose reagent kits with 3 kinds of different chromogens.The bias,total imprecision,inter-cepts,slope rates,nonlinearities,carryover rate and drifts were calculated.The interference evaluation test was performed according to the document EP7-A2.Results The bias and total imprecision of three kinds of reagent kits were all within allowed ranges.No statistically significant differences were showed in intercepts,slope rates,nonlinearities,carryover rate and drifts.1450 turbidity chyle,5 g/L hematoglobin and 0.03 g/L vitamin C did not interfere with the assay of three kinds of glucose reagent kits with differ-ent chromogens.342 μmol/L free bilirubin,342 μmol/L conjugated bilirubin did not interfere with the detection of reagent with MAOS.Conclusion The glucose detention reagents with three different chromogens have good accuracy and precision,and various performance indexes all conform to the clinical application requirements,reagent with chromogen MAOS is better than other chro-mogenic reagents in the anti-interference performance.
