How to find out if i have a penicillin allergy?

Skin test: The formal means is to have skin testing done by a doctor. The agent is prepared to a standard small dose and injected under the skin. Reaction or not is assessed in a standard time interval.

Test: IN the US there is skin testing available to evaluate PCN allergy. If this test is negative it is usually followed by an oral challenge to amoxil (amoxicillin).

Covered by insurance: Testing for penicillin allergy involves skin testing to many of the different components of penicillin (major and minor). This testing is relatively painless and can be done in 2-3 hours. Insurance usually covers such testing.
