How does the screening work?

Our expert Genomic Diagnostics team will use the DNA from your blood sample to test for the most common genetic changes that cause cystic fibrosis, spinal muscular atrophy and fragile X syndrome.

If both partners are identified as carriers for cystic fibrosis or spinal muscular atrophy, or the female partner is identified as a carrier for fragile X syndrome, they are considered to be a carrier couple.  

When the female partner is not identified as a carrier, the couple is considered to have a much lower risk of having an affected child.
