Tracing a tumor's unique "fingerprint"

The FDA-cleared Pathwork Tissue of Origin Test uses microarray technology employed in highly advanced medical research. Microarrays are powerful tools for diagnosis because they can measure the genomic profile of a sample (biopsy) of tumor tissue, and rapidly compare it with the profiles of many types of tumors in which the tissue of origin is already known.

The Tissue of Origin Test measures the expression pattern of a tumor that is metastatic, poorly differentiated or undifferentiated, This expression pattern, made up of more than 2.000 genes, can answer many diagnostic questions all at one time. The accuracy of this microarray analysis has been defined in clinical studies.
