E. None of the above
Answer and topic summary
The answer is A. 31-year-old who was in contact with a person who has active TB
Tuberculosis (TB) is a worldwide health concern and is deadly. A purified protein derivative (PPD) test can be used to screen for TB. A PPD test is considered positive depending on the patient’s risk factors. Remember, we measure induration, NOT erythema. See below for a high-yield list of positive PPD tests (not exhaustive):
>5 mm: HIV, immunosuppressive condition, or recent contact with active TB case
>10 mm: IVDU, came from a country with a high TB prevalence (<5 y prior), health care worker, resident/employee in a high-risk congregate setting
>15 mm: everyone else
