In this study measurements were made under more natural viewing conditions. Observers used a projection colorimeter to adjust the appearance...

Background. Skin tests with soluble b-lactams can be used to diagnose immediate and delayed hypersensitivity (HS) reactions to b-lactam antibiotics. Very few studies have been performed with children with suspected b-lactam allergy. In these studies, immediate HS to b-lactams was diagnosed by skin tests in 4.9% to 40% of children. The diagnostic and predictive values of immediate responses in s...
