Skin allergy testing based on the prick test technique must be performed by medical staff able to correctly assess both the skin response and the pathogenic importance and clinical relevance of any sensitisation detected.
Prick tests are carried out by applying an extract drop on the skin of the forearm volar surface and pricking the skin through the drop with a pre-determined length of prick.
It is also necessary to perform negative (diluent solution) and positive (histamine 10 mg/ml) control tests. Skin reactions should be read 15-20 minutes from application, a time that corresponds to the skin reaction peak.
Your doctor will assess test positivity based on the most appropriate criteria.
