Thoughts on how to improve the quality of multicentre patch test studies.

• Multicentre patch test studies (MPTSs) can contribute useful information for diagnostic and preventive measures. The aim of the present paper is to propose how to perform high-quality MPTSs. To this end, factors of significance for the patch test result are discussed with regard to the standardization and calibration of high-quality MPTSs. The 16 factors discussed are scored 0, 1, 2, or 3, depending on the relative importance of a particular factor for the patch test result. The total score of an MPTS allows it to be ranked as having doubtful, acceptable, high or excellent quality. A total score of 30 is possible. Depending on the total score the MPTSs are grouped into those with a doubtful, acceptable, high, and excellent quality. In conclusion, high-quality MPTSs can be performed and are facilitated if a guideline and check list are followed when the study is being planned. The scoring enables the calculation of a total score, which can be used for quality ranking.
