In this section
The laboratories aim to report all genomic tests within the NHS England genomic test reporting time guidelines (examples below). Please note that reporting times will vary depending on the test type and referral type. The turnaround times for specific laboratory services can be found on the relevant GLH service profiles.
Following the recent introduction of new elements of the test directory a number of services are reporting results outside of the below guidelines. If a service you use is affected you will be contacted in writing in due course, explaining the impact on the service and our recovery plan. In the meantime, if you have any queries or concerns please contact the laboratory.
