ClinConnect Summary

This is a prospective, open-label investigation of skin testing with the Penicillin Skin Test Kit in subjects at least 18 years of age with a self-reported history of possible IgE-dependent penicillin hypersensitivity.

At screening on Day 1, subjects and their parents/legal guardians (if applicable) will sign the informed consent form/ pediatric assent form. Following consent/assent, demographic information and medical history will be obtained, including prior and current medication use. Subjects will also be asked if they have had a respiratory infection in the past 2 weeks or antibiotics...
