U.S., Aug. 15 -- ClinicalTrials.gov registry received information related to the study (NCT07765563) titled 'Reliability of Expired Allergens in Patch Testing: A Comparative Study With Non-Expired Series' on July 07.
Brief Summary: Patch testing remains the gold standard in the diagnosis of allergic contact dermatitis. Patches used in testing consist of a wide spectrum of allergens, with variability in the stability of products over time. Due to limited allergen stability, careful storage and preparation is needed to prevent product degradation over time. Expiration dates are provided by manufacturers to ensure stability and reactivity, while minimizing the risk of product degradation contributing to inaccurate testing results. Preparation...
