Can you test for antibiotic allergies?

Yes.: Yes, however it is somewhat limited. The only fda approved antibiotic that we can skin test for is penicillin. It is tested in small amounts by scratch testing and then small amounts are injected, in increasing doses. Finally if these are negative a small oral dose is given. It is important to test for possible pencillin allergy as this is still an effective, inexpensive antibiotic.

Yes: But blood testing is not at all accurate. True testing requires a drug provocation challenge through an allergist trained in this method. Call the allergist you are seeing and find out if they do them, since many do not.
