Brief summary
The purpose of this study is to evaluate the diagnostic performance and safety of ascending doses of mercury, aluminum and palladium metal allergens proposed for inclusion in a metal allergen panel. Optimal dose will be selected based on the lowest dose of each allergen eliciting a positive response in 70-90% of subjects tested.
Detailed description
This is a single-center, double-blind, randomized study to compare the diagnostic performance (primary) and safety (secondary) of ascending doses of mercury, aluminum and palladium in 20 adult subjects who have a clinical history of contact dermatitis and have had a past positive patch test to one of the allergens on this study. Investigators and subjects will be blinded to the exact location of each dose within the allergen panel but will not be blinded to the allergen being tested, nor the range of allergen doses within each panel.

Inclusion criteria
1.15 years of age or older. 2\. History of contact dermatitis. 3\. Positive patch results to 1) mercury (elemental), 2) aluminum (aluminum chloride hexahydrate, aluminum hydroxide and/or aluminum lactate) or 3) palladium (sodium tetrachloropalladate and/or palladium chloride) within the past 10 years. 4\. Male or non-pregnant non-lactating female. Female subjects must state, at visit one that they are not pregnant, not lactating nor are they intending to become pregnant for the course of the study. 5\. Has understood and signed the approved Informed Consent/Assent Form, which is consistent with all institutional, local and national regulations. Assent Form for all minor subjects (ages 15-17) must be signed by the guardian/parent.
Exclusion criteria
1. Breastfeeding or pregnant or intending to become pregnant for the course of the study. 2. Topical treatment with corticosteroids or other immunosuppressive agents on or near the test area during the 7 days prior to inclusion in this study. 3. Systemic treatment with corticosteroids (equivalent to \> 10 mg prednisone) or other immunosuppressive agents during the 7 days prior to inclusion in this study. Inhaled treatments are permitted. 4. Treatment with ultraviolet (UV) light (including tanning) during the 3 weeks prior to inclusion in this study. 5. Acute dermatitis outbreak or dermatitis on or near the test area on the back. 6. 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). 7. Participation in a clinical trial of an investigational drug, treatment or device other than T.R.U.E. TEST during this study or 3 weeks prior to inclusion in this study. 8.
