Most Americans may be wrong about penicillin allergy

New studies say most Americans who say they are allergic to penicillin, could be wrong.

These studies show that skin tests for people who believed that they were allergic to penicillin tested negative for the allergy.

In one study 94 percent of nearly 400 people who thought they were allergic to the antibiotic tested negative for a penicillin allergy.

And in a second study a skin test was performed on 38 people who all believed they were allergic, however all of those people tested negative.

The studies were presented at the meeting of the American College of Allergy, Asthma, and Immunology on Friday.
