Abstract

Thirty-five patients who showed 90 one plus (+) patch test reactions to 28 patch test chemicals at Day 2 (D2) were retested to the chemicals at D7. On retesting, 60% (54/90) reactions were positive but 42% (38/90) were negative at D9, suggesting that false positive patch test reactions were common when more than one positive reaction was obtained by concomitant patch testing. On retesting, the total % positivity was reduced from 344 to 241 suggesting that the true index of sensitivity was falsely exaggerated by concomitant testing.

摘要

35名患者在第2天（D2）对28种斑贴试验化学物质出现90次一级（+）斑贴试验反应，在第7天对这些化学物质进行了重新测试。重新测试时，60%（54/90）的反应在第9天呈阳性，但42%（38/90）呈阴性，这表明当通过同时进行斑贴试验获得多个阳性反应时，假阳性斑贴试验反应很常见。重新测试时，阳性总百分比从344降至241，这表明同时测试会错误地夸大真正的敏感性指标。
