This is helpful for diagnosing allergic diseases when combined with other clinical information.

Why might someone need this test?Doctors might suggest this test if there are signs of a penicillin allergy or in situations where traditional skin allergy tests can't be used. This includes cases with extensive skin disease, recent use of antihistamines, uncooperative patients, or when there's a high risk of a severe allergic reaction from skin testing.

What type of sample is required for this test?0.6 mL serum. A blood draw is needed.

Important to know:A single test isn't enough for a complete allergy diagnosis. A healthcare provider will consider this test result alongside other clinical evaluations.
