Abstract:
Objective To evaluate the performance of the ABX Micro C-reactive protein(CRP)in determination of CRP.Methods The analytic characteristics including precision,carry-over,linearity, stability,interference and comparability were examined.Results The coefficient of variation(CV)was less than 5.1%,10% and d.3% for within-run,between-run and between-day,respectively.Carryover was less than 1.2%.Whole blood samples held at either room temperature or 4℃ were stable for 48 hours with relative deviation less than 6.0% relatively.Linear range was 1.0-70.0 mg/L using undiluted samples.The comparison between the ABX Micro CRP and Behring Nephelometer Ⅱ was well correlated Both serum:Y=0.996 7X-0.398 5,r~2=0.965 9;serum for BN Ⅱ,whole-blood samples for the ABX Micro CRP:Y=0.908 8X-0.138 2,r~2=0.959 4;both serum and whole-blood samples for the ABX Micro CRP: Y=1.001 7X-0.898 2,r~2=0.952 7.No obvious interference was observed by hyperhemoglobinemia and hyperlipidemia.Conclusion The determination of CRP test with ABX Micro is accurate and reliable.
