The prevalence of a disease is 12% in population X (n = 10,000). Two screening tests have been developed for this disease. Individuals first undergo screening test 1, which has a sensitivity of 85% and specificity of 80%. Only individuals who test positive from screening test 1 undergo the more invasive screening test 2, which has a sensitivity of 90% and a specificity of 80%.
