The results were compared with those from a new kit with 2018 expiry.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results:<\/jats:title>\n<jats:p>Ten patients in group-1, eight patients in group-2 and seven patients in group-3 developed positive reactions of identical intensities and mostly from identical allergens from all four kits. The major contact allergens eliciting positive reactions of identical intensities were parthenium in nine, five and three patients, colophony in four, one and zero patients, fragrance mix in three, three and one patients, thiuram mix in three, one and one patients, and paraphenylene diamine in two, one and three patients from group-1,-2, and -3, respectively.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Limitations:<\/jats:title>\n<jats:p>Small number of patients in each group remains the major limitation of the study. Whether or not these results can be extrapolated with patch test results from other similar patch test kits available across countries also needs confirmation.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st5\">\n<jats:title>Conclusion:<\/jats:title>\n<jats:p>The patch test allergens can be used beyond labeled expiry dates but needs confirmation by a few large studies and using other available patch test kits. This is important as the relevance of patch test results for individual allergen in this scenario may remain debatable requiring careful interpretation.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/ijdvl_390_19","type":"journal-article","created":{"date-parts":[[2021,4,23]],"date-time":"2021-04-23T10:32:59Z","timestamp":1619173979000},"page":"188-195","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Patch
