Enhancing Genetic Testing Transparency with the Global Test Registry (GTR)

The Global Test Registry (GTR) serves as a web-based platform aimed at improving transparency in genetic testing. Established following the 2008 SACGHS recommendations, GTR enables healthcare providers to locate laboratories and details of genetic tests. It encourages voluntary sharing of test information and supports research endeavors. The registry covers single-gene tests, multiplex panels, and pharmacogenetic tests, documenting essential metadata such as assay methodologies and clinical utility. GTR currently includes 82 laboratories across 24 countries, encompassing 608 tests for 487 conditions.

  3. Growth

  4. Scope Repository of raw reads from next generation sequencing Any Platform is in Scope Align Sequences including BAM, SAM files Worldwide shared contentNCBI, EBI, DDBJ (www.insdc.org) Minimally useful metadata, separable and indexed Sample Attributes Method details (library prep, etc.) Capture method/reagents Assembly used for alignments (BAMS and VCF files)

  5. Purpose • Enable health care providers to find information about laboratories and genetic test that they do • Encourage providers to voluntarily share information about the availability and scientific basis of their tests • Facilitate research and new scientific discoveries • Each test assigned a unique accession/version number Arose from the 2008 SACGHS recommendation to the Secretary of HHS to create a publicly available, Web-based registry to enhance the transparencyof genetic testing and to assist efforts in reviewing the clinical validity of laboratory-developed tests.

  6. Overview of Information Laboratory Contact information Certification(s), license(s) Test information Intended use Target population Assay limitations Methodology Analytical validity Clinical validity Clinical utility Ordering information Test credentials (e.g., FDA, CAP, ASHI) Additional resources Other NLM resources and professional practice guidelines well integrated in the GTR

  7. Scope and Content Scope Single-gene tests for heritable mutations Molecular, cytogenetic and biochemical tests; Multiplex panels and arraysHLA tests are in scope for GTR Pharmacogenetic tests Content 82 labs registered in 24 countries with 608 registered tests 487 total conditions assessed by registered tests 588 genes measured by registered tests GeneTests Laboratory Directory is reflected in GTR Test results are not part of the GTR!
