Section 15 – What happens if my baby has a higher chance of a chromosomal or genetic change because of something identified on the fetal anomaly scan?

You will have been told that there is something identified on your fetal anomaly scan which means that your baby may be at higher chance of having a chromosomal change or a genetic condition. The health professional will discuss the findings of your scan with you and tell you which tests they will offer. This may include SNP array or other genetic tests.


We may offer you an amniocentesis to see whether the baby has a chromosomal change or a genetic condition. If we offer you an amniocentesis you should be aware that this test can cause a miscarriage.


If you have had chorionic villus sampling (CVS) or amniocentesis earlier in pregnancy for a higher chance result from the screening test for Down’s syndrome, Edwards’ syndrome or Patau’s syndrome, the laboratory may be able to carry out extra tests on the sample to look for other changes in chromosome or genes.
