Background: Patch testing is routinely used in contact dermatitis clinics because it is the gold standard for the evaluation of potential allergic contact dermatitis. Objective: The study was undertaken to evaluate possible differences in reactivity between the Finn Chamber and IQ-Ultra patch-testing methodologies. Methods: Patients were patch-tested simultaneously with the Finn Chamber and IQ-Ultra patch tests. Ten standard allergens set by the North American Contact Dermatitis Group were used for both techniques. Results: Both patch tests had a significant agreement in detecting all of the allergens. An “almost perfect agreement” was noted for ethylenediamine dihydrochloride, quaternium-15, mercapto mix, black rubber mix, balsam of Peru, and nickel sulfate; “substantial agreement” for formaldehyde, bisphenol A epoxy resin, and 4-tert-butylphenol formaldehyde resin; and “moderate agreement” for potassium dichromate. Conclusion: The Finn Chamber and IQ-Ultra patch tests had a good agreement in the detection of the 10 standard allergens that were tested.

Introduction: Allergic contact dermatitis (ACD) is a growing concern due to increased use of cosmetics and topical medications routinely and exposure to a large number of allergens on day-to-day basis. Patch testing is a reliable method for detecting the causative antigens in suspected cases. Aims And Objectives: To assess the demographic profile, pattern of ACD, and patch test profile of suspected cases of ACD attending contact dermatitis clinic of our department. Materials And Methods: It was a prospective study in which all the patients with suspected ACD attending OPD of department of dermatology over a 3 month period were analysed. Patch testing was done using the most common antigens primarily, and other batteries were used depending on patient requirement and availability. Results: A total of 50 patients were enrolled in the contact dermatitis clinic over a period of 3 months. Hand eczema was the most common pattern seen in 23 cases followed by feet eczema, hand and foot eczema, facial eczema, forearm and leg eczema and photoallergic contact eczema. A total of 32 (64%) gave positive patch test results, with nickel sulfate being the most common allergen identified followed by cobalt sulfate & potassium dichromate. Conclusion: Common allergens identified in our study were more or less similar to studies from other parts of India
