In a series of 56 clinically healthy persons with no history of syphilis and negative VDRL tests but reactive fluorescent treponemal antibody absorption (FTA-ABS) tests, 20 spontaneously developed nonreactive FTA-ABS tests in a period of eight months or less. All but one of these had been of 2+ or less fluorescence. In such a situation, the serologic tests for syphilis (VDRL and FTA-ABS tests) should be repeated at intervals for up to a year before coming to a decision regarding the diagnosis of syphilis. Laboratories could facilitate that decision by reporting degrees of fluorescence of the FTA-ABS test.
在一组56名临床上健康、无梅毒病史且性病研究实验室玻片试验（VDRL）结果为阴性但荧光密螺旋体抗体吸收试验（FTA - ABS）结果为阳性的人中，20人在八个月或更短时间内FTA - ABS试验结果自发转为阴性。除一人外，所有这些人的荧光强度均为2+或更低。在这种情况下，在对梅毒诊断做出决定之前，梅毒血清学检测（VDRL和FTA - ABS试验）应每隔一段时间重复进行，最长达一年。实验室通过报告FTA - ABS试验的荧光强度可以帮助做出该决定。
