# Penicilloyl G

> This test measures specific antibodies in your blood that react to Penicilloyl G, a primary component of penicillin antibiotics. It helps show whether your immune system is sensitized to this drug, which is important if you have had reactions like hives or swelling after taking antibiotics. This result helps identify a potential immediate allergy to penicillin. However, this test cannot definitively prove you are safe to take the medication, as some allergies require skin testing for confirmation.
