To request a HRD test, please send a tumour tissue sample together with the completed test request form to one of the partner NHS Genomic Laboratory Hubs. It will be then forwarded to Myriad Genetics Inc. in the United States where the myChoice® CDx HRD test will be performed. The results will be returned to the GLH within 14-21 days for further dissemination to the requesting clinician.

The provision of the HRD testing service is funded by global co-promotion agreement between AstraZeneca & MSD. The service is delivered in accordance with arrangements agreed with NHS England and NHS Improvement and facilitated by NHS Genomic Laboratory Hubs. 

To discuss HRD testing in the private sector, please contact us at:

The Myriad myChoice® CDx assay can identify patients as being HRD-positive by detecting tBRCA1/2 mutations and measuring genomic instability.2
