Pathwork Diagnostics is applying new discoveries in genomics to unmet clinical needs in oncology. Using proprietary technologies, Pathwork Diagnostics plans to harness the power of genomics information to develop FDA-cleared microarray-based tests that provide physicians with clinically actionable information not available with current diagnostic methods.
Our first test, the Pathwork® Tissue of Origin Test, is expected to aid in the diagnosis of the tissue of origin for poorly differentiated or undifferentiated tumor specimens. National Comprehensive Cancer Network (NCCN) guidelines emphasize the significance of identifying the tissue of origin so that standard-of-care, tissue-directed treatment recommendations can be followed.
