Details
Penicilloyl G and V Profile - This test measures the body's allergic reaction to components found in penicillin G and V, known as penicilloyl G and penicilloyl V. It's a detailed test that helps in understanding if someone has allergies to penicillin, using a method that checks for specific IgE antibodies in the blood. This is helpful for diagnosing allergic diseases when combined with other clinical information.
