A prenatal DNA test (Chorionic Villi Sampling (CVS) or Amniocentesis) will allow you to identify the sex of your unborn child or to determine who is the biological father.  You would need to arrange for a hospital to collect the relevant DNA sample on your behalf.  Once collected please arrange for the sample to be delivered direct to our laboratory within 3 working days.  Please note, the hospital DNA sample procedure carries a 1% - 2% risk of miscarriage.
