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.

Commissioning group

Core

Overlapping idications

• R29 Intellectual disability – microarray, fragile X and sequencing or other relevant broader tests should be used in preference individuals where Angelman syndrome is plausible but not highly likely • R263 Confirmation of uniparental disomy test should be used to confirm likely UPD detected on methylation and copy number testing
