Referring Samples

When requesting test activations, including using existing samples stored in the laboratory, all requests must be submitted in writing. This can be using our referral form, proforma, email (to or letter. Any request made verbally should be confirmed in writing as above.

General guidelines

  • Samples are normally referred by hospital consultants.
  • Certain tests referrals are only accepted from the Regional Genetics Service (details available on request).
  • GP referrals are not encouraged for specialist tests, though are permitted for routine karyotyping.
  • For Non-NHS Referrals, please provide the name and address for invoicing at the time of referral. Testing will not be undertaken until this information is received, although DNA may be extracted and stored.
  • We do not offer paternity testing or self-referral.

Referral card

A fully completed referral card should accompany each sample.

Referral cards must be legible and provide:

  • patient's full name
  • date of birth and NHS/hospital number
  • patient's postcode
  • BUPA policy number and pre-authorisaton number if applicable
  • full name and address of referring clinician
  • referral reason and test/s required.


  • In submitting samples the referring clinician confirms that consent for testing has been obtained. Material may be stored (where applicable) from all patients referred unless consent for this is specifically denied and recorded on the referral form.
  • It is the responsibility of the referring clinician to request a laboratory test and to ensure that all samples are correctly labelled and request forms are completed to a minimum standard (see above).

Service Agreement

By sending a sample, accompanied by a completed laboratory referral form, the user enters into an agreement for the Genetics Laboratory to provide the service or test requested and agrees to the terms and conditions.
