Available before pregnancy
Testing may be considered before marriage, while planning a pregnancy or during pregnancy, depending on individual circumstances.

Carrier Screening
Genetic information to support family planning decisions.
Carrier screening assesses whether a person carries selected genetic variants associated with inherited conditions, even when they have no symptoms.

OVERVIEW
About VISTA™
Many healthy people carry a variant associated with a recessive genetic condition. If both partners carry variants related to the same condition, there may be a chance of passing the condition to a child.
VISTA™ uses next-generation sequencing to analyse multiple genes associated with inherited conditions. The result is intended to support discussion with healthcare professionals about reproductive options.

FEATURES
Key features
Panel options for different needs
Options range from a focused set of conditions to broader panels covering a larger number of genes.
Supports couple-based consultation
Results should be interpreted clinically, with partner testing or genetic counselling considered when appropriate.

FAQ
Frequently asked questions
QDoes being a carrier mean that I will develop the condition?＋
AFor many autosomal recessive conditions, carriers do not develop typical symptoms. The meaning varies by condition and inheritance pattern, so individual results require clinical interpretation.
QDoes a negative result exclude all inherited conditions?＋
ANo. Variants outside the test scope and changes that are technically difficult to detect may not be identified. A negative result does not reduce risk to zero.
Important information
The test has limits determined by the genes, regions and variant types analysed. It may not detect large structural changes, balanced translocations, inversions, polyploidy, methylation abnormalities or other changes outside its scope.
