Webno FDA-approved IVD assay is available to test for a rare disease or condition. A laboratory may also opt for an LDT when there is a newly identified or newly reported marker that is not included in the panel of an existing FDA-approved IVD assay. An LDT must be verified by demonstrating that it has clinical utility for the intended WebStandard method validation parameters used for quantitative assays, however, do not apply here. Rather, contingency tables, Bayesian statistics and statistical hypothesis testing for inter-rater agreement must be used. This article provides an overview of simple, practical tools, which can be used to verify the analytical performance of such ...
