实验性的：Positive Response Rates: 7 new and 4 reformulated allergens
Subjects will be patched with TRUE Test Panels 1.3, 2,2 and 3.2.
Panel 1 allergens nickel sulfate (0.60 mg/cm2), potassium dichromate (0.054 mg/cm2), fragrance mix (0.050 mg/cm2) and ethylenediamine dihydrochloride (0.050 mg/cm2), Panel 2 allergen Methyldibromoglutaronitrile (0.0053 mg/cm2) and Panel 3 allergens Gold sodium thiosulfate (0.075 mg/cm2), Hydrocortisone-17-butyrate (0.020 mg/cm2), Bacitracin (0.60 mg/cm2), Parthenolide (0.0030 mg/cm2), Disperse blue 106 (0.050 mg/cm2 in PVP), 2-Bromo-2-nitropropane-1,3-diol (Bronopol) (0.25 mg/cm2) will be evaluated
|
Three allergen panels will be applied to the upper backs of study subjects and will be worn for 48 hours.
Allergen test sites will be evaluated at 3, 4, 7(±1) and 21(±2) days post application.

Late reactions are positive reactions that initially occur at 7-21 days after application of the panels. Persistent reactions are positive reactions that persist from one visit to the next. Numbers reported only include late or persistent positive patch test reactions. Not all positive reactions are late or persistent. |
