Contact Dermatitis, 1984
Colophony (rosin) has been fractionated into 2 parts, an acidic and a neutral fraction. Routine patch testing with neutral components gives positive reactions at a 40% higher frequency than routine patch testing with colophony (20%) (w/w in pet.). A concentration of 60% colophony is suggested for routine patch testing.

The Journal of Pediatrics, 1949
Summary We tried to simulate the Vollmer patch test in the field of coccidioidomycosis with a patch test made with coccidioidin material. Out of 120 subjects tested with the filter paper method similar to that of Vollmer's, twenty-seven positive patch tests were noted, or 22.5 per cent. With the ointment method, four positive patches out of 100 known

Archives of Pediatrics & Adolescent Medicine, 1949
AN ATTEMPT was made to develop a histoplasmin patch test similar to the tuberculin patch test. Since many analogies exist between histoplasmosis and tuberculosis, such a test was expected to be practicable. Histoplasmin patch tests were prepared in the following way: 16 square centimeters of thin filter paper was saturated with a solution consisting ...

The reproducibility of patch tests
British Journal of Dermatology, 1999There is conflicting evidence regarding the reproducibility of patch testing. Discordant results have been reported in up to 44% of cases. The clinical relevance of these discordant patch tests has not been previously assessed. We studied 383 consecutive patients receiving simultaneous duplicate patch testing on opposite sides of the upper back with 10

Reproducibility of patch tests
Journal of the American Academy of Dermatology, 1989Patch tests with a series of 39 substances were performed in 41 patients on one side of the upper aspect of the back. Testing was repeated on the contralateral side of the back 1 week later (sequential testing). In 35 other patients, duplicate patch test series were simultaneously applied on both sides of the back (concomitant testing).

Clinics in Dermatology, 1986
Abstract Living plants and natural plant products, such as balsams, turpentines, and the aroma chemicals found in perfumes and in flavorings, are among the most common causes of contact dermatitis. Most of the dermatitis-producing plants belong to a limited number of plant families, and many of the plant sensitizers that have been isolated belong to ...

Patch testing: Facts and controversies
Clinics in Dermatology, 2013The German dermatologist, Josef Jadassohn (1863-1936), first presented the results of his innovative patch-testing technique in 1895. The safety and efficacy of this diagnostic tool has stood the test of time and is still the gold standard for the diagnosis of allergic contact dermatitis (ACD).

Patch testing—a recapitulation

This article reviews the use of the patch test and emphasizes its utility in the practice of dermatology.
