Readings were performed on day (D) 2, D3 and D4 after application of patch tests in 88 patients. 90 patch test reactions in 49 patients were interpreted as allergic and of past or present relevance. A single D2 reading detected 58 of the allergic reactions with 32 false-negatives and 23 false-positives. A single D3 reading detected 77 allergic reactions, with 13 false-negatives and 17 false-positives. A single D4 reading detected 85 allergic reactions, with 5 false-negatives and 9 false-positives. Therefore, if only a single reading is feasible, it is better performed on D4 than on D3.
对88例患者进行斑贴试验后，分别在第2天（D2）、第3天（D3）和第4天（D4）进行读数。49例患者的90次斑贴试验反应被判定为过敏反应，且与既往或当前情况相关。单次D2读数检测到58例过敏反应，有32例假阴性和23例假阳性。单次D3读数检测到77例过敏反应，有13例假阴性和17例假阳性。单次D4读数检测到85例过敏反应，有5例假阴性和9例假阳性。因此，如果只能进行单次读数，在D4进行比在D3进行更好。
