Can We Improve Peanut Allergy Diagnosis with New Laboratory Tests?

Blog

A recent study published in The Journal of Allergy and Clinical Immunology: In Practice investigated the usefulness of peanut-specific allergic antibody levels for the diagnosis of peanut allergy.

The researchers analyzed the usefulness of the ISAC test and standard serologic test for peanut allergy. The ISAC test is used to determine allergic antibody binding to individual peanut proteins.

The results of the study found that neither test was useful in determining which patient had a peanut allergy, and so oral food challenge still remains the gold standard for diagnosing food allergy.
