Skin test of patients with allergic contact dermatitis. Practical aspects of patch test
The patch test is generally a recommended tool required to identify the cause of allergic contact dermatitis.
Done in good condition and interpreted properly, this bioassay represents a very complete scientific method of investigation with well-defined rules, a proof of the status of a patient with allergic sensitization. Dermatologists which are familiar in using patch tests, confirm that the discovery of an allergen, responsible for producing a dermatitis, is important to prevent its recurrence.
