Objectives: To assess the cost-effectiveness of the new T-SPOT®.TB assay versus the Tuberculin Skin Test (TST) for screening contacts for latent tuberculosis (LTBI) in Switzerland. Methods: Health and economic outcomes of isoniazid (INH) treatment of 20- and 40-year-old close contacts were compared in a Markov model over a 20-year period following screening with TST only (at three cut-off values), T-SPOT.TB alone or in combination with the TST. Results: T-SPOT.TB based treatment was cost-effective at €11,621 per life-year-gained (LYG) in the younger and €23,691/LYG in the higher age group. No TST-based programs…
