Pharmaceutical Applications of a Multi-Stage Group Testing Method
An important problem in pharmaceutical research is whether individual testing of components should be made, or alternatively, if the components should be tested in groups. It is important that the experiment is economically viable since, for multi-stage procedures, the cost of additional stages must be taken into consideration along with the cost of testing the mixtures of components. Optimum group sizes are calculated for two-stage and three-stage members of Li’s family of algorithms and for row-and-column procedures, along with the minimum number of tests required to determine all of the active components. Finally, comparisons are made between the costs of the one-, two- and three-stage procedures using two different cost functions for the cost of testing mixtures of components.
