I want to find encounters for screening for infectious and parasitic diseases, with a specificity scale of 0 and any timing, in the first panel. In the second panel, I want to find screening for disease or disease precursors in asymptomatic individuals for early detection and treatment, with a specificity scale of 100 and any timing.
