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.
