The South West genomic Laboratory Hub is committed to providing a service of the highest quality.
Information on accreditation, quality assurance including turn around times, user feedback and complaints procedures can be accessed below
Accreditation
Bristol Genetics Laboratory (BGL) and Exeter Genetics Laboratory (EGL) are UKAS accredited medical laboratories numbers 9307 and 8092. UKAS assesses against the International Standard for medical laboratories, BS EN ISO15189:2012. Further information on accreditation is available via the UKAS website.
Details of activities that are currently provided under the scope of accreditation can be found at:
- EGL Schedule of Accreditation - link to follow
In certain circumstances laboratory tests will be performed outside the scope of accreditation. This may arise when new services are introduced, for which UKAS accreditation is yet to be awarded. Application for extension to the laboratory scope will be submitted, however, whilst accreditation is pending the test continues to be performed to the same rigorous internal quality control standards and protocols as accredited tests. It should be noted that elements of the Whole Genome Sequencing service are undertaken by an external provider and are, therefore, provided outside the laboratory’s UKAS scope of accreditation.Methods that are currently pending accreditation are as follows:
Activity | Comments |
---|---|
DNA / RNA extraction from FFPE, and RNA extraction from blood using the Maxwell RSC 48 |
New instrumentation and methodology. Extension to UKAS accredited scope currently in progress. |

External Quality Assessment
Target Turnaround Times
The SWGLH is working towards 90% compliance with national reporting time guidelines stated in the table below:

Cancer Genomic Turnaround Times
Below are the turnaround times (TAT) for the Cancer Genomic Services at the South West Genomic Laboratory Hub (SWGLH). Cancer Genomic Services for the SW GLH are delivered from the Bristol Genetics Laboratory. Unless otherwise stated TAT is measured in calendar days from the date of sample receipt at Bristol Genetics to the point at which a result is returned to the requestor.
Further information on requesting a test can be found at SWGLH Sample and Test Information.
