【摘要】 目的　评价 TRUST和 TPPA在梅毒血清学诊断和室间质评中的价值。方法　采用 TRUST和 TPPA检测 80例梅毒患者和 6 7例非梅毒患者血清 ;1998～ 1999年采用 TRUST检测室间质评样本 ,从 2 0 0 0年开始采用 TPPA检测室间质评样本。结果　梅毒患者 TRUST和 TPPA阳性率分别为 86 .3% (6 9/ 80 )与 10 0 % ;TRUST在室间质评样本中的敏感性 44 .44 % ,特异性 90 .0 0 % ,符合率 6 8.75 % ,而 TPPA的敏感性、特异性、符合率达到 10 0 %。两者的敏感性存在明显差别 (χ2 =9.35 ,P<0 .0 1)。结论　 TPPA具有很高的敏感性、特异性 ,可作为临床诊断梅毒的首选方法更多还原

【Abstract】 Objective To evaluate the value of Tolidime Red Unheated Serum Test (TRUST) and External Quality Assessment.Methods To test the serums of syphilis and non syphilis by TRUST and TPPA.The samples of External Quality Assessment from 1998 to 1999 year and 2000 year were tested by TRUST and TPPA respectively.Results The positive rates of syphilis serum tested by TRUST and TPPA were 86.3%(69/80) and 100%.The sensitivity and specificity of TRUST were 44.44% and 90.00% in External Quality Assessment.The accuracy was 68.75%.The sensitivity and specificity and accuracy of TPPA were all 100%.There was an evident difference between their sensitivties(χ 2=9.35,P<0.01).Conclusions TPPA has very high sensitivity and specificity.It can be first selected clinical method to diagnostic Syphilis.更多还原
