BACKGROUND: The patch test has become the standard method of investigating patients with allergic contact dermatitis. Many countries have developed standard screening allergens to make patch testing more efficient. A series of the Chinese Standard Screening Allergens were studied and modified.

OBJECTIVE: This study investigated the frequency of contact allergies in suspected allergic contact dermatitis and tested the practicality of the Chinese Standard Screening Patch Test Allergens.

METHODS: A total of 1,135 patients suspected of having allergic contact dermatitis were patch tested. Three hundred twelve (27.5%) were men, and their age ranged from 2 to 75 years old (mean age, 34.3 years), 823 (72.5%) were women, and their age ranged from 2 to 76 years old (mean age, 33.0 years). Nanjing Medical University supplied the Chinese Standard Screening Allergens and Finn-Chamber. All patients were patch tested according to the Chinese Standard Screening Patch Test Allergens with Finn-Chamber the protocol as established by the International Contact Dermatitis Research Group (ICDRG).

RESULTS: From the 1,135 patients suspected to have allergic contact dermatitis, 650 (57.3%) had at least one positive reaction. Nineteen (95%) of the Chinese Standard Screening Patch Test Allergens had positive reactions higher than 1%. Of 485 patients with negative reaction to the Standard Allergens, 106 patients were tested with other suspected contactants according to history. Thirty-nine (36.8%) had positive reactions to the contactants they provided. The total positive rate therefore increased by 3.4%.

CONCLUSIONS: Our study results indicate that the Chinese Standard Screening Patch Test Allergens are suitable for use in routine clinic in China.
