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

1. Living affected individual (proband) where the individual +/- family history meets one of the criteria.
The proband has:
a. Diffuse gastric cancer ( <50 years). b. gastric in situ signet ring cells or pagetoid spread of signet ring cells under 50 years c. diffuse gastric cancer at any age with a personal history or FDR with cleft lip or cleft palate. d. double primary diffuse gastric cancer and lobular breast cancer (both <70 years). e. diffuse gastric cancer and ≥ 1 FDR/SDR with diffuse gastric cancer at any age. f. diffuse gastric cancer at any age and ≥1 FDR/SDR with lobular breast cancer <70 years. g. Lobular breast cancer and ≥FDR/SDR has diffuse gastric cancer (≥ 1 case occurred < 70 years). h. 2 cases of lobular breast cancer<50 years e.g. bilateral or multiple ipsilateral tumours 2. Deceased affected individual (proband) where (i) the individual +/- family history meets one of the above criteria, (ii) appropriate tissue is available (tumour or normal), and (iii) no living affected individual is available for genetic testing NOTE: At least one cancer should be histologically confirmed Genetic testing may occasionally be appropriate outside these criteria following discussion at a specialist MDT with a cancer geneticist present
