Horizon carrier screening is a simple test that checks to see if you are a carrier of one or more autosomal recessive or X-linked conditions. The majority of people are carriers of at least one genetic condition. Most carriers are healthy, however, they can have a risk to have a child with a genetic condition. Having carrier screening allows you to make more informed reproductive decisions by helping you understand your carrier status. You can have Horizon carrier screening before or during pregnancy.
How is carrier screening performed?
A blood test is taken. The type of blood test depend on what your doctor recommends. The basic test includes screening for Cystic Fibrosis (CF), Spinal Muscular Atrophy (SMA), Fragile X Syndrome, Duchenne Muscular Dystrophy (DMD). We can test for up to 274 genetic conditions in the extended panel. Results take two weeks to come back.
What are my reproductive options if I am a carrier?
If you are a carrier you partner should be tested. If you are both carriers of the same condition, or you are a carrier of an X-linked condition the following reproductive options could be considered:
- Natural conception
- *Prenatal testing such as amniocentesis or a CVS for the specific condition
- *In-Vitro Fertilisation (IVF) with Preimplantation Genetic Diagnosis (PGD)
- *Use of donor sperm or donor egg who is not a carrier for the condition
