So I am often asked by patients, "will the testing hurt"?....and "how long does it take"? Unlike when your mother or father may have been tested, current allergy skin testing does not hurt! There are no needles involved, just the use of tiny plastic prongs which place allergens on the skin eight at a time. When I test children, I use the back (so they can't scratch) and I use the arms on adults (so they can see the results). A positive (histamine) and negative (saline) control are used to ensure accurate results. It takes approximately 15 minutes for the allergic reactions to develop (usually a small hive at the site where the allergen was placed) at which time your results are read. Its that easy!
Allergy skin testing is used to determine sensitivity to environmental and food allergies. It can also be used to evaluate penicillin and venom allergy.
