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

All patients diagnosed with diabetes diagnosed less than 9 months of age

Marked hyperglycaemia is common in very preterm patients due to an immature pancreas. These individuals should be referred for genetic testing only if hyperglycaemia requiring insulin treatment is still present at 32 weeks equivalent gestational age.

Where possible, clinicians are asked to submit samples from the probands parents for the DNA to be stored (R346) to allow follow-up of variants

Sample requirements

Sample Requirements Each sample must be sent labelled with 3 patient identifiers and must state the sample type clearly on the sample container. Sample Rejection Samples may be rejected for the following reasons: 1. Samples and request form do not show at least three identical patient identifiers 2. The sample is in the incorrect collection media 3. The request form is not sufficiently completed 4. The sample is not of sufficient volume 5. The sample is too old Sample Storage and Volume Required: Perirpheral blood in an EDTA tube: Adult and children 4 ml, Infants (0-2 years) 1 ml or a DNA sample (3-5µg of purified DNA). Where it is not possible to collect peripheral blood we will accept a saliva sample (please contact the lab for specific details). Storage, sample packing and transportation: Blood should be stored at 4°C where possible. Send at room temperature by first class post or by courier. Patient/Clinician Instructions: N/A Factors affecting performance of test/interpretation of results: Clotted samples are unsuitable for DNA analysis. Blood Samples in incorrect anticoagulant tubes may be rejected.
