Routine path testing with a series of 6 industrial biocides containing methylene‐bis‐thiocyanate (Cytoc 3522®), benzosothizolin‐3‐one (BIT), chlorocresol (Preventol CMK®), 2‐n‐octyl‐4‐isothiazolin‐3‐one (Kathon 863®), polyhdroxymethylene monobenzylether (Preventol D2®) or 1,3,5‐tris (hydroxy‐ethyl) hexahydrotrizine (Grotan BK®) was carried out in 6 Danish out‐patient clinics to evaluate guinea pig allergy test results with the same compounds. A total of 1652 consecutive patients with dermatitis were tested. The usefulness of this patch test battery was limited. There were a few positive reactions to Cytoc 3522®, BIT and the 2 formaldehyde releasers, Preventol D2® and Grotan BK®. These reactions could not, however, be explained. The MOAHL‐index (% of Male patients. Occupational cases, Atopic patients, Hand eczemas, and 1 eg ulcers/stasis dermatitis) for patients from the 6 clinics showed equal frequencies of male patients and atopics, but significant differences in the frequencies of occupational cases, hand eczemas, and leg ulcers/stasis dermatitis, indicating possible variations in referral patterns, use of patch tests, and/or environmental factors.
