Prenatal testing

Routine prenatal genetic testing and some disease-specific testing is delivered by the East GLH Laboratories at Cambridge, Nottingham and Leicester.

The pathway for all prenatal testing is through the appropriate local laboratory at Cambridge, Leicester or Nottingham. Tests for certain specialist clinical indications are delivered by our partner GLHs across England.

Samples should be sent to the local laboratory for DNA preparation and routine testing. Where specialist testing is required, DNA samples will then be transferred to the designated GLH. All enquiries should be directed to us, as your local GLH via Please add ‘PRENATAL’ to the subject field of emails.

To facilitate rapid prenatal testing for familial variants, please download and complete the new prenatal notification form (below) and send in advance of the procedure to the local laboratory with as much notice as possible. This will ensure that the testing GLH has all the necessary information and samples to expediate a rapid report.
