Results and discussion

Results of examinations:
A reproducible positive pin-prick response to a 5% aqueous solution of propionic acid was obtained in 3 of 91 patients suffering from chronic uticaria; patients were presumed to have prior exposure with propionic acid as a food preservative. There was no response observed among 247 normal control (non-uticaria) subjects.
