Prenatal screening consists of one or more blood tests, which are ordered by your health care provider and can be done at any hospital or laboratory.
Prenatal screening tells you the chance of your baby having a chromosome abnormality like Down syndrome, trisomy 18 or an open neural tube defect. It is offered free of charge as a choice to all pregnant women in BC. If a risk is identified, you will be offered a prenatal diagnostic procedure.
Once prenatal screening is complete, some women may be offered prenatal diagnostic procedures such as amniocentesis or chorionic villus sampling.
For more information, women and their families can visit the BC Prenatal Genetic Screening Program.
