Genetic carrier screening is a blood or saliva test that you can take prior to beginning your IVF cycle to determine if you are a carrier for a genetic condition/mutation. This can be beneficial for couples with a family history of genetic conditions such as cystic fibrosis, sickle cell disease, etc. because it allows them to determine the chance of passing on the disorder to their child. Having this discussion with your doctor is critical for developing your IVF cycle plan as preimplantation genetic diagnosis (PGD) will likely be advised to assess each embryo for the presence of the mutation.
