The National Institute of Standards and Technology (NIST) compares, evaluates, and validates DNA (and other biologic) markers for clinical diagnostics. Where applicable, we develop high-throughput techniques for both solid tumor and noninvasively (i.e., serum) collected sample analysis. We incorporate broad-based consensus via interdisciplinary NIST-sponsored workshops into the development of reference material(s). In general, NIST activities in fragile X, TP53, and mitochondrial variants provide specialized technical and scientific expertise for measurement needs, thus fostering economic and clinical development.
