Clinical values of fast detection of hs-CRP in distinguishing between transudate and exudate / 国际检验医学杂志

ABSTRACT

Objective To evaluate the clinical value of fast detection of high sensitivity C-reaction protein(hs-CRP)in distinguis-hing between transudate and exudate.Methods 100 cases of patients were enrolled in the investigation.The levels of TP,LDH, GLU in serum and pleural effusion respectively,as well as the level of hs-CRP in the pleural effusion.Results According to Light standard,82 cases of patients were diagnosed as transudate(transudate group)and 18 cases of patients were diagnosed as exudates (exudates group).The sensitivities of Rivalta test,TP(pleural effusion)/TP(serum)and LDH(pleural effusion)/LDH(serum) were 83.14%,80.49% and 79.27%,respectively.Hs-CRP showed 84.15% sensitivity and 27.78% specificity at a cutoff value of 5 mg/L.TP(pleural effusion)/TP(serum)and LDH(pleural effusion)/LDH(serum)had the highest specificities,and both were 100.00%.The levels of LDH(pleural effusion)/LDH(serum)and hs-CRP in transudate group were significantly higher than those in exu-dates group(P<0.05).Combined detection of hs-CRP,TP(pleural effusion)/TP(serum)and LDH(pleural effusion)/LDH(serum)had the highest specificity (100.00%).Conclusion The fast detection of hs-CRP in pleural effusion is sensitive,combining with other tests can prove its specificity.The fast assay of hs-CRP has special clinic value in the distinguish between exudate and transudate.
