Sample Tracking at a Large-Scale Genetics Laboratory: From Sample Receipt through Reporting with Sharon Mexal, PhD, MB(ASCP), CGMBS

  • [Recording unavailable]


    Clinical diagnostic testing in a CLIA/CAP laboratory involves comprehensive sample tracking from sample receipt, wet lab preparation, and result interpretation.  However, even with the most rigorous lab consumable barcoding and sample tracking system, a patient sample could still encounter a rare mislabeling or mishandling prior to receipt or during preparation in complex laboratory workflows. All these factors highlight the clear need to ensure sample identity and integrity prior to embarking on molecular-based testing. In this webinar, Dr. Sharon Mexal, VP of Clinical Operations at Ambry Genetics, will share their high-throughput Clinical Diagnostic Genetic Testing Laboratory’s experience with integration and scale-up of a cost-effective sample tracking and NGS data quality assurance workflow for germline hereditary testing.
