A simple spot test for the detection of PAS in urine has been described and its sensitivity compared with that of other methods such as the Ehrlich's reagent and the ferric chloride tests. In patients receiving 4 g. PAS the three methods gave similar results in urine specimens collected within eight hours. The new test is an inexpensive micro method which can easily be performed on a large scale. There is no reaction with sulfonamide or salicylic acid derivatives.
已描述了一种用于检测尿液中对氨基水杨酸（PAS）的简单斑点试验，并将其灵敏度与其他方法（如艾氏试剂法和氯化铁试验）进行了比较。在接受4克PAS治疗的患者中，这三种方法对8小时内采集的尿液标本检测结果相似。这种新试验是一种廉价的微量方法，易于大规模操作。它与磺胺类药物或水杨酸衍生物无反应。
