Study on feasibility of Coapresta2000 automatic coagulation analyzer for detecting CRP / 国际检验医学杂志

ABSTRACT

Objective To explore the feasibility of the Coapresta2000 automatic coagulation analyzer for detecting C‐reactive protein(CRP) .Methods The performance of the Coapresta2000 automatic coagulation analyzer for detecting CRP was analyzed ,in‐cluding accuracy ,linearity ,precision ,carryover rate and the correlation between the Ottoman automatic special protein real time ana‐lyzer and the Coapresta2000 automatic coagulation analyzer .Results The men recovery rate of 3 batches of reagent by the Coapres‐ta2000 automatic coagulation analyzer for detecting CRP for detecting plasma CRP was 106 .0% with better accuracy ;the within‐run precision was less than 10% and the inter‐day precision was less than 15% ;the carryover rate was 0 .32% ;the related equation in the Ottoman automatic special protein real time analyzer and the Coapresta2000 automatic coagulation analyzer for detecting plas‐ma CRP was Y=0 .001 2X+0 .489 ,the correlation coefficient was r2 =0 .997 5 ,the difference was not statistically significant(P>0 .05) .The CRP results of plasma sample detected by these two instruments was highly correlative ;the linearity in the Coapres‐ta2000 automatic coagulation analyzer for detecting CRP was 0-200 mg/L .Conclusion The Coapresta2000 automatic coagulation analyzer for detecting CRP has better within‐run precision ,low carryover rate ,high correlation with the Ottoman automatic special protein real time analyze ,which has a value for further study .
