Information for referrers


How to refer a patient for treatment for heathcare professionals

Please view our information for patients for acceptance criteria. We look forward to seeing you. Our current waiting time for a first PGD appointment is about 8-10 weeks following receipt of a referral letter. We require that all couples have been seen by their local genetics service before coming to see us.

If you would like to refer a couple, please complete either the PGD standard referral form (Word 58Kb) or HLA referral form (PDF 90Kb). Please send the complete form to:

PGD genetic team
Clinical genetics
7th floor, Borough Wing
Guy's Hospital
Great Maze Pond
London SE1 9RT.

Tel: 020 7188 1364/020 7188 1392


When referring your patients, please include:

  • the names and date of births of both partners
  • relevant molecular or cytogenetic reports (we need these before we can process appointments). All results must have been confirmed in an NHS accredited laboratory
  • a brief reproductive history
  • relevant clinical details if one of the partners is affected by a genetic condition, or any other medical condition.

If referrals are sent elsewhere or relevant information is not included there may be a delay in offering your patient an appointment.

Please remember that we usually need DNA samples to be available from the couple and other family members, either an affected child or the parents of genetic carriers for linkage analysis.

If you think that such samples may not be available, please call to discuss before referring the couple.
