Preanalytical Evaluation & Molecular Testing Services

The Pre-analytical Evaluation and Molecular Testing (PEMT) Service ensures the use of adequate and accurately classified tumor and ancillary specimens for molecular testing. Sample processing including macro- and micro-dissection followed by nucleic acid extraction is provided. Molecular tests performed include several single-gene assays (Sanger sequencing, allele-specific qPCR, sizing), micro-satellite instability (MSI) testing, and targeted next-generation sequencing (NGS) assays. All services are performed in a CLIA-certified environment and all molecular assays are accompanied with full data analysis (including bioinformatic analysis for NGS) and a complete report.


  • Retrieval of appropriate materials for testing (fluids, blocks or slides) from bio-specimen archives
