A small study comparing results of the rapid plasma reagin (RPR) teardrop card test performed in the field, with results of Venereal Disease Research Laboratory (VDRL) and fluorescent treponemal antibody absorption (FTA-ABS) tests performed in the laboratory on venous blood specimens from the same suspected yaws patients was undertaken in Columbia in July 1975. The results suggest that the RPR teardrop card test may be used to screen for infectious, or potentially infectious, yaws patients under field conditions, but that it will not reliably detect patients with VDRL titres of 1:2 or less, or all patients in whom sera are reactive in the FTA-ABS test.
1975年7月在哥伦比亚进行了一项小型研究，比较了现场进行的快速血浆反应素（RPR）泪滴卡片试验的结果，与在实验室对来自相同疑似雅司病患者的静脉血标本进行的性病研究实验室（VDRL）试验和荧光密螺旋体抗体吸收（FTA - ABS）试验的结果。结果表明，RPR泪滴卡片试验可用于在现场条件下筛查感染性或潜在感染性雅司病患者，但不能可靠地检测出VDRL滴度为1:2或更低的患者，也不能检测出所有血清在FTA - ABS试验中呈反应性的患者。
