Diagnostic Testing and Reagents in the Age of Molecular Pathology
Jaleh Mansouri, M.D.
The increasing number of molecular pathology tests performed today for diagnostic, prognostic and therapeutic purposes has introduced a new set of complex issues regarding the oversight of both home brew (in-house) and manufacturer kit-based tests. While most analyte specific reagents (ASRs) do not currently require approval by the US Food and Drug Administration (FDA), laboratories developing higher complexity tests (e.g. fluorescence in situ hybridization, FISH), must be certified under the Clinical Laboratory Improvement Amendments (CLIA). These clinical laboratories retain the primary responsibility for establishing rigorous performance characteristics of a particular test prior to implementation and are required to issue appropriate disclaimers for ASRs.
In vitro diagnostic multivariate index assays (IVDMIA) are emerging as complex molecular tests which employ a number of ASRs including antibodies and genetic markers in order to provide more comprehensive and specific information on the prognostic, therapeutic and biologic course of the disease in question. These tests may eventually provide clinicians with a blueprint for individualized treatment of the patient. Examples of IVDMIAs approved by the FDA include MammaPrint (Agendia), Tissue of Origin Test (Pathworks Diagnostics), and AlloMap (XDx). The advent of IVDMIAs and other technologically advanced assays with critical diagnostic and therapeutic implications will likely redefine the validation and clearance protocols of regulatory agencies for clinical pathology laboratories.

discovers and develops innovative diagnostic technologies for oncology, designed to improve patient care from the
time of diagnosis through selection of appropriate treatment. The company's initial diagnostic test offerings are: (1) CancerTYPE ID¨, which improves cancer classification, especially in patients with metastatic cancer and an unknown primary. It is based on a 92-gene qRT-PCR panel and capable of identifying up to 39 tumor types with 86% accuracy. (2) THEROS Breast Cancer Index® - This provides a more complete picture of recurrence risk and therapeutic
options for patients by combining the results of the THEROS H/I and THEROS MGI tests, to better stratify ER-positive, node-negative breast cancer patients. bioTheranostics is also working on prostate cancer prognosis and drug-response profiling.

is the world leader in rabbit monoclonal antibody (RabMAb®) technology. Using our proprietary RabMAb technology, we have developed high quality antibodies (EP Clones™) and IHC kits (EpiPrecision™, EpiVision™) for anatomical pathology use. With the benefits of RabMAb technology, EP Clones offers superior binding affinity and specificity. EP Clones have been specifically developed and optimized for use in pathology laboratories for immunohistochemical staining of formalin-fixed
paraffin embedded tissues. We are committed to providing high quality products and services that consistently meet the needs of our customers. For more information contact us at 877-772-2622, IVDinfo@epitomics.com, or visit our website at www.epitomics.com/diagnostics.
is the world's first provider of genetically defined, human genomic reference standards, including FFPE cell line blocks, and purified genomic DNA. These standards offer a sustainable source of reference material to diagnostic laboratories, proficiency schemes, and manufacturers, and provide an unprecedented level of control to the molecular pathology community. Variability in DNA extraction from tumor biopsies and a lack of standardization are currently major sources of error in diagnostic laboratories. The availability of genetically defined controls will provide a gold standard for development and quality control of assays, directly improving analytical accuracy and clinical outcomes.
