Does routine testing for tuberculosis (TB) in lowrisk areas help to reduce the incidence of TB?
Does routine testing for tuberculosis (TB) in low-risk areas help to reduce the incidence of TB? Evidence-Based Answer: Probably not. Routine screening of the general population (including low-risk areas) to reduce the incidence of TB has a number needed to screen (NNS) to prevent 1 case of active TB of 8,000 to 25,000 patients (SOR: C, population models). Current guidelines recommend targeted testing in elevated-risk populations in whom the NNS is lower (SOR: B, national evidenced-based guidelines).
