Request / Find a Test Tool

The National Genomic Test Directories specify which genomic tests are commissioned by the NHS in England, to be delivered by Genomic Laboratory Hubs.

This tool allows clinical teams to search all of the genomic tests available to patients through the National Testing Directory. From here you can find out more details about each test and information about how to order them. These tests can only be ordered by clinical teams, if you are a patient looking to request a test please speak to your clinical team directly.

Eligibility Criteria

Reanalysis of data which has previously been interpreted and reported is required, due to:
1. New clinical information or clinical events which would substantially change the relevant genomic target,
2. Sufficient time has passed since the initial analysis that new gene discovery will have substantially increased the relevant genomic target (national approach to be confirmed), OR
3. A technical or scientific advance requires reanalysis of a group of tests to detect an important new source of actionable diagnoses (national approach to be confirmed)
