|Condition or disease||Intervention/treatment||Phase|
|Allergic Contact Dermatitis||Device: AI-based smartphone application Diagnostic Test: Allergen patch||Not Applicable|
Study participation involves three visits to the study site on Days 1, 3, and 5, and completion of a demographics and allergy history questionnaire. Researchers will review medical history and current medications. On Day 1 a patch will be applied with 10 allergens and a routine skin examination will be conducted and a photograph will be taken of the forearm. On day 3, subjects will return to remove the patch test and have photographs of the area taken. On day 5, the final assessment for allergic contact dermatitis will be performed and photographs of the area taken.
Key Information: The most common side effect of skin testing is slightly swollen, red, itchy bumps (wheals). These wheals may be most noticeable during the test. In some, an area of swelling, redness and itching may develop a few hours after the test and remain for a couple of days. Rarely, allergy skin tests can produce a severe, immediate allergic reaction. The patches are worn on the forearm for 48 hours. During this time, bathing and activities that cause heavy sweating should be avoided. Irritated skin at the patch site may indicate an allergy. If a positive test result is documented, a medical professional will provide education and recommend follow up with primary care provider.

Experimental: Allergy Skin Patch Testing
On day 1, subjects will have a allergy skin patch test applied and a routine skin examination. On day 3, the patch test will be removed and documentation of the test sites using iPhone app. On day 5, the final assessment for allergic contact dermatitis will be conducted by a medical professional.
Device: AI-based smartphone application
AI-based smartphone application to record and interpret the patch test results
Diagnostic Test: Allergen patch
Allergens applied to a patch which is placed on the skin on the forearm region. The patch contains 10 dime-sized disks which contain a different allergen.
- AI algorithms predictions of reactions [ Time Frame: 6 months ]Number of times the AI algorithms matches the human review of photographs of skin patch tests classification of reaction. The accuracy for the classification of regions within the test panel that either were a reaction (reaction grade 1+) or not (grade 0).
- Fitzpatrick skin type assessment [ Time Frame: 10 months ]Number of times the AI algorithms matches the human review of photographs of skin patch tests over the entire range of Fitzpatrick skin types. The Fitzpatrick skin typing categorize skin type according to how much melanin is present.
