Diagnostic Accuracy of Teledermatology in Patch Test Interpretation

Not Applicable

Completed

• Conditions: Teledermatology
• Interventions: Diagnostic Test: In-clinic interpretation; Diagnostic Test: Photo interpretation

• Registration Number: NCT06213545
• Lead Sponsor: Mahidol University

Brief Summary

The goal of this clinical trial is to learn about accuracy of teledermatology in patch test interpretation in patch test\'s patients population. The main question\[s\] it aims to answer are:

* Accuracy of teledermatology in patch test interpretation by dermatologist

* Accuracy of teledermatology in patch test interpretation by Residency

* Accuracy of teledermatology in patch test interpretation by Scitentist

* The factors influencing the interpretation of remote dermatologic patch test results from photographs of patients.

Participants will

* do patch test in Siriraj hospital and come to follow up at 48 hr and 72 hr for interpretation of patch test

* take a photo at home and sent the photo to contact clinic via online application or email on the day of 48 hr, 72 hr and 7 days following the interpretation of patch test

Researchers will compare in-clinic group and telephoto group to see if the accuracy of patch test interpretation is more or less.
