Drug allergy testing helps determine whether you truly have an immune-based allergy to medications such as penicillin or amoxicillin. Many people carry a penicillin allergy label based on a childhood reaction that may no longer be relevant or was never a true allergy. This service is especially helpful for patients who avoid penicillin due to past reactions, unclear history, or family concerns.
After careful assessment of the history of prior exposure and reaction, further evaluation steps are determined. Some patients require skin and intradermal testing, while others can progress to a medication challenge at the clinic.
Depending on the reaction, it is deemed whether you’re still allergic to penicillin or not. The medical record is updated accordingly.
Based on the outcome, it is determined whether you are still allergic to penicillin.
This testing is not performed during an active allergic reaction.
Penicillin and related antibiotics are effective, affordable, and often safer than alternatives. When someone is incorrectly labeled as allergic:
Here is the surprising truth: Nearly 90% of people who think they are allergic to penicillin are not actually allergic. Sometimes the reaction was due to a virus, not the medication itself. In other cases, the allergy subsides over time. Testing helps remove this incorrect label, opening the door to better treatment options.
If you have been avoiding penicillin due to an unclear or outdated allergy history, drug allergy testing can provide clear answers and peace of mind. An accurate diagnosis helps ensure you receive the safest and most effective medications when you need them.
