Patch testing is considered the gold standard for the diagnosis of allergic contact dermatitis. Whereas previous surveys have evaluated the patch testing practices of dermatologists, little information is available on the use of patch testing by allergists.
The objective of this study was to examine the prevalence of patch testing and associated methodologies used by allergists in the United States.
A cross-sectional survey of all US Fellows of the American Academy of Allergy, Asthma and Immunology was conducted.
Of 1,239 questionnaires mailed, 519 (42%) were returned. Fifty-three percent of allergists reported performing patch testing. The majority (89%) patch tested 5 or fewer patients per month. Allergists who evaluated for latex allergy were twice as likely to patch test than those who did not. The most common patch test reading schedule was at both 48 and 72 hours (48%). Thirty-three percent of respondents performed only a single patch test reading. The majority (72%) used TRUE Test. Only 4% patch tested for Type IV allergy to dust mites.
Many more allergists patch test than initially hypothesized. The patch testing methodologies used by allergists are similar to those of dermatologists.
斑贴试验被认为是诊断过敏性接触性皮炎的金标准。尽管先前的调查评估了皮肤科医生的斑贴试验实践，但关于过敏症专科医生使用斑贴试验的信息却很少。
本研究的目的是调查美国过敏症专科医生进行斑贴试验的患病率及相关方法。
对美国过敏、哮喘与免疫学会的所有会员进行了横断面调查。
在邮寄的1239份问卷中，有519份（42%）被退回。53%的过敏症专科医生报告进行斑贴试验。大多数（89%）过敏症专科医生每月对5名或更少患者进行斑贴试验。评估乳胶过敏的过敏症专科医生进行斑贴试验的可能性是未评估者的两倍。最常见的斑贴试验读数时间是48小时和72小时（48%）。33%的受访者只进行一次斑贴试验读数。大多数（72%）使用TRUE Test。只有4%对尘螨进行IV型过敏斑贴试验。
进行斑贴试验的过敏症专科医生比最初假设的要多得多。过敏症专科医生使用的斑贴试验方法与皮肤科医生相似。
