Summary

This study looks at whether a blood test called BAT inhibition can tell if venom immunotherapy (allergy shots) has protected people from future insect stings. Currently, the only reliable way to check is by stinging patients with live insects, which is not widely available. Researchers will compare the blood test results with sting challenges in 219 adults with wasp venom allergy to see if the test can replace the sting.
