An open, prospective, multi-center study to evaluate the bioequivalence of polyvinylpyrrolidone formulations of T.R.U.E. TEST fragrance mix and thimerosal allergens.
We are conducting an open, prospective, multi-center study to evaluate the bioequivalence of polyvinylpyrrolidone formulations of T.R.U.E. TEST fragrance mix and thimerosal allergens. Bioequivalence will be determined in 40 adult subjects, 20 per allergen, with a clinical history of contact dermatitis and a positive patch test (current or previous) to the corresponding reference petrolatum allergen ("sensitives").
Endpoint Classification: Bio-equivalence Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Diagnostic

Occupational Contact Dermatitis in North American Production Workers Referred for Patch Testing: Retrospective Analysis of Cross-sectional Data From the North American Contact Dermatitis Group 1998 to 2014.
Little is known about the epidemiology of contact dermatitis in production workers (PWs).
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
