Abstract

The macroscopic rapid plasma reagin (RPR) and reagin screen (RST) card tests for syphilis were compared. Test specimens were also examined with the Venereal Disease Research Laboratory (VDRL) microscopic slide test; those reactive in the card or slide tests were examined with the fluorescent treponemal antibody-absorption (FTA-ABS) procedure. Agreement between the card tests with 2,300 specimens was 99%; among all three reagin tests it was 96.3%. With 348 specimens reactive in one or more of the tests, there was 75.6% agreement among all three tests. The FTA-ABS was reactive with 71% of the RPR- or RST- and 65% of the VDRL-reactive specimens. The comparison showed that the card tests give results in close agreement with those of VDRL while offering a number of practical advantages over it.

摘要

对梅毒的宏观快速血浆反应素（RPR）和反应素筛查（RST）卡片试验进行了比较。还用性病研究实验室（VDRL）显微镜玻片试验对检测标本进行了检查；对卡片试验或玻片试验呈反应性的标本用荧光密螺旋体抗体吸收（FTA-ABS）程序进行检查。2300份标本的卡片试验之间的一致性为99%；在所有三种反应素试验中一致性为96.3%。在348份在一项或多项试验中呈反应性的标本中，所有三项试验之间的一致性为75.6%。FTA-ABS与71%的RPR或RST反应性标本以及65%的VDRL反应性标本呈反应性。比较表明，卡片试验的结果与VDRL的结果非常一致，同时具有一些优于VDRL的实际优势。
