NBS Molecular Assessment Program (MAP)

   Provide quality management guidance and support for
    molecular testing in NBS laboratories
     Partnership between MQIP, NBS laboratories and APHL
   Gaps in current CLIA guidelines for molecular testing
     CMS does not provide a genetic testing specialty – recommends use of
      general guidelines for high-complexity tests
     Standard regulatory framework does not allow for complexity involved
      in molecular testing
     Rapidly changing field would render CLIA specialty guidance obsolete
     Inflexible regulations may prevent use of new technologies
   Provide management component for NBS quality
    improvement program specific for molecular testing

NBS Molecular Assessment Program Overview


   Detailed assessment criteria is modeled from the
    following documents:
       NNSGRC Performance Evaluation Assessment Scheme (PEAS)
       CLIA regulations
       Molecular Pathology Checklist (CAP)
       Standards and Guidelines for Clinical Genetics Laboratories
        (ACMG)
       Clinical Laboratory Standards of Practice (NYSDOH)
       Good Laboratory Practices for Molecular Genetic Testing for
        Heritable Diseases and Conditions (MMWR)
                MAP Evaluation Categories
    Assessment categories for evaluation of entire molecular
     testing process:
    Pre-Analytic                  Analytic                        Post-Analytic
    Test methods and              Test method specifications      Reporting of specific
    mutation selection                                            nucleic acid targets
    Nucleic acid extraction and   Test accuracy and reliability   Recommended molecular
    sample handling                                               nomenclature
    “Clean” and “post-            QA/QC concerns specific for     Determine need for
    amplification” areas          molecular tests                 genetic consultation
