Prenatal testing

Prenatal genomic testing is delivered by the East GLH laboratories and by our partner GLHs across England.

Prenatal and maternal samples should be sent to your local laboratory at Cambridge, Leicester or Nottingham for testing. Please use the standard test referral form for submitting samples.

Non-urgent advice: NEW Nov 23: Prenatal Invasive Testing videos and information

The North East and Yorkshire Genomic Medicine Service Alliance (NEY GMSA) have produced a series of videos and associated information leaflets for patients on:

  • Family History of a Known Genetic Condition: If you are considering a prenatal invasive test when you have a family history of a known genetic condition.
  • Following a Higher Chance Screening Result: If you are considering a prenatal invasive test following a higher chance screening result.
  • Following an Unexpected Ultrasound Finding: If you are considering a prenatal invasive test following an unexpected finding on your Ultrasound scan.

You can find the resources on the NEY GMSA website here.

Molecular prenatal notification form

To facilitate rapid prenatal testing for familial molecular variants, a prenatal notification form should be sent in advance of the sampling procedure.

Submitting this form helps to ensure that the testing laboratory has all the necessary information and samples available to expedite a rapid report.

Send completed documents and copies of relevant genetic reports to us at cuh.geneticslaboratories@nhs.net (please include ‘prenatal test’ in the subject heading).

Red cell disorder testing

The North West GLH (Manchester) is the designated centre for East GLH referrals Haemoglobinopathies. As per the standard pathway, all prenatal samples should be sent to your local laboratory for DNA preparation, routine testing and rapid transfer to the North West GLH.
