What is this test?
This test measures insulin-specific IgE antibodies directed against porcine insulin in your blood. IgE is an immune-system protein that can form in response to a suspected allergen.
Why might I need this test?
Your clinician may order this test if you have had an allergic reaction to insulin, particularly porcine insulin. It may be used alongside your symptoms, medication history, and other allergy testing.
How is the test performed?
A blood sample is collected and analyzed in the laboratory for antibodies specific to porcine insulin. The result is generally reported as detected or not detected, depending on the laboratory method.
How do I prepare for the test?
No special preparation is usually required. Tell your clinician about any insulin allergy symptoms, recent reactions, and the type of insulin you have used so the result can be interpreted in context.
Reference range
Fasting: 2.6-24.9 μIU/mLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Detected porcine insulin-specific IgE suggests that your immune system has produced an antibody response to porcine insulin. When interpreted with symptoms such as hives, swelling, wheezing, or low blood pressure, this finding may support a porcine insulin allergy. A not-detected result does not completely exclude an allergy, so your clinician should interpret it alongside your medical history.
Short name
Porcine insulin IgE
