About Pathwork Diagnostics

Pathwork Diagnostics, Inc., is a privately held company  in Redwood City, CA, that develops and commercializes innovative, high-value molecular diagnostics for oncology. The company’s  Pathwork® Tissue of Origin Test is a microarray-based gene expression test that aids in identifying challenging tumors, including poorly differentiated, undifferentiated, and metastatic cancers. It is the only FDA-cleared and Medicare-covered molecular test of its kind. The company provides the Tissue of Origin Test through its CLIA-certified, CAP-accredited laboratory.

In the U.S., approximately 150,000 newly diagnosed cancer patients may have a tumor that is metastatic, undifferentiated, or poorly differentiated, and often difficult to diagnose. These patients may benefit from the Tissue of Origin Test, because knowing the site of origin for these challenging tumors may lead to more effective treatment.
