Skin Testing Overview
Allergies Tested for in a Skin Test
- Allergic asthma, rhinitis, and conjunctivitis
- Food allergies – With some foods, only half of all positive tests are true positives. Test results may need further confirmation with a food challenge.
- Some medication allergies – Skin testing has been validated and standardized for the evaluation of some medication allergies. This is true for penicillin allergy skin testing. However, skin testing is not well-defined for other antibiotic and drug allergies.
- Venom allergies to wasps, hornets, bees, yellow jackets, and fire ants
Methods for Skin Testing
Skin Prick or Puncture
Skin prick testing is sensitive, but not very specific. It can accurately predict positive results less than 50 percent of the time. However, a negative skin test is 95 percent accurate in confirming the absence of an IgE-mediated allergy. Therefore, a false-negative skin allergy test result is uncommon.
Skin Prick-by-Prick Testing for Food Allergy
Intradermal Skin Test
Intradermal skin testing is typically performed when a prick or puncture test comes back negative but your doctor still believes you may be allergic to a particular substance. Because intradermal skin testing is highly sensitive, it is optimal for detecting venom allergies. However, intradermal skin testing is unacceptable for testing food or latex allergies due to the possibility of severe systemic reaction.
Because intradermal skin testing is more sensitive, there may be many small, positive reactions that are not clinically significant. This equates to more false-positives. Additionally, with intradermal skin testing, there is a higher risk of inducing a systemic allergic reaction, so prick or puncture testing is usually recommended prior to intradermal testing. This is especially true when testing for airborne allergens.
Side Effects of Skin Testing
Anaphylaxis is rare but can occur during skin testing. It is almost always associated with intradermal testing without prior prick or puncture testing.
