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.
