Penicilloyl V

This test measures specific antibodies in your blood that react to Penicilloyl V, a common form of penicillin antibiotic. It helps show whether your immune system views this medication as harmful, which is important if you have experienced symptoms like hives or swelling after taking antibiotics. This information assists doctors in evaluating the likelihood of a penicillin allergy. However, this test alone cannot confirm a diagnosis or predict exactly how severe a future reaction might be.
