Porcine Insulin Antibody Titer, Serum
A blood test that measures antibodies against pig-derived (porcine) insulin, which may help evaluate suspected insulin allergy or immune-related insulin resistance.

What is this test?
This blood test measures the titer, or relative amount, of antibodies your immune system has formed against porcine insulin. Porcine insulin is insulin originally obtained from pigs and may be used when human insulin is not suitable or available.
Why might I need this test?
The test may be ordered if you have had an allergic reaction after receiving insulin or if insulin is not controlling your blood glucose as expected. It can help determine whether an immune response to porcine insulin may be contributing to your symptoms.
How is the test performed?
A blood sample is drawn and tested in a laboratory to detect and estimate the level of porcine insulin antibodies. The result is reported as a titer, which is a measure of antibody concentration rather than a standard blood glucose or insulin level.
How do I prepare for the test?
No special preparation is usually required for this test. If you are taking insulin, do not stop or change it unless your healthcare professional instructs you to do so. Follow any fasting or timing instructions provided by the laboratory or ordering clinician.
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.
A detectable titer shows that antibodies against porcine insulin are present. A significant level may support a diagnosis of an immune reaction to porcine insulin, particularly in someone with allergic symptoms or poor response to insulin therapy. The result must be interpreted with your insulin type, symptoms, treatment history, and other laboratory findings because low levels may not cause symptoms.
Short name
Porcine insulin antibody titer
