The patient, Asuncion, is an eight-year-old girl from Argentina. She received the BCG vaccine for tuberculosis about one year before coming to the United States. Upon entering school in the United States, she must take a skin test for tuberculosis (TB). Asuncion tries to refuse but is told it is a requirement. She allows the nurse to apply the test to her arm. Three days later, the test site has a large red lesion and the skin is starting to slough (peel off). From the information given in the case study, it is unclear whether Asuncion could potentially pose a TB infection risk to her classmates. Why was this test an inappropriate one for Asuncion and what would be a more useful alternative?
