Conditions
Outcome Measures
Primary Outcomes (1)
Number of participants with positive, negative, irritant or doubtful patch test responses and concordance between hydrogel and petrolatum allergens
Number of patch test responses will be recorded, concordance between hydrogel and petrolatum allergens will be measured
Days 3-21
Secondary Outcomes (5)
Evaluation of panel adhesion at visit 2 prior to panel removal
Day 2
Evaluation of subject reported itching associated with test panels at visit 2 following panel removal
Day 2
Evaluation of subject reported burning associated with test panels at visit 2 following panel removal.
Day 2
Evaluation of tape irritation
Day 21
Evaluation of chip irritation
Day 21
Study Arms (1)
Positive reactions, Concordance with reference allergen
EXPERIMENTALAll subjects will be patch tested with 11 experimental and 11 reference allergens. Rates of positive reactions will be evaluated using Cohen's kappa calculation.

- Acute dermatitis outbreak or dermatitis on or near the test area on the back.
- Known or suspected infection of the skin, joints or other site(s) associated with metal exposure
- Condition such as; fibromyalgia, chronic fatigue, depression, cognitive impairment, flu-like symptoms, diarrhea and/or headache without at least one of the symptoms related to metal exposure listed in Section 6.6.
- Condition such as; psoriasis, dermatitis herpetiformis, mycosis fungoides or cutaneous T-cell lymphoma that may confound the evaluation of allergic contact dermatitis.
- Inability to comply with patch test study requirements including multiple return visits and activity restrictions (e.g., protecting test panels from excess moisture due to showering or vigorous activity).
- An opinion of the Investigator that deems the potential subject to be non-compliant, unable to return for study visits or complete the study as detailed in the protocol.
