Pathwork Diagnostics

The Pathwork Tissue of Origin Test

The Pathwork^® Tissue of Origin Test is an innovation in molecular diagnostics. Cleared by the FDA in 2010, this gene expression–based test uses a tumor's own genomic information to aid in identifying challenging tumors, including metastatic, poorly differentiated and undifferentiated tumors. The test provides objective clinical information previously unavailable to physicians for tissue of origin identification. The company provides the Tissue of Origin Testing Service through its CLIA-certified laboratory.

The Tissue of Origin Test is part of a growing family of products that includes lab service tests for formalin-fixed, paraffin-embedded (FFPE) specimens. The Pathwork Tissue of Origin Testing Service also includes the Tissue of Origin Endometrial Test and the Tissue of Origin Head & Neck Test, used by the Pathwork Diagnostics pathologist in combination with the original Tissue of Origin test to provide the most accurate result.
