The Power of Knowing


An accurate and affordable pre-pregnancy and pregnancy screening test for 155 genetic disorders.

What is Carrier Screening

Carrier screening, usually done before or during a pregnancy, is a genetic test used to determine if you carry a gene for certain genetic disorders.

Who should Consider Carrier Screening?

Cordlife carrier screening test can provide important information for people who:

are currently pregnant or planning a pregnancy
are planning to receive donor egg, sperm or embryo
have an increased risk for a specific disorder

Testing can be carried out either before or during pregnancy (before the 14th week). If you are already pregnant, your reproductive partner can be tested together.

Why Should You
Consider Carrier Screening?

Carriers of a gene mutation are usually healthy and show no symptoms.

Most people do not know they are a carrier of an inherited genetic disorder until they have a child with the disease. Carrier screening can give you information about your reproductive risk and your chances of having a child with a genetic disorder.

ACOG Recommends

If the test result returns as positive for a mutation, any patient treatment plans should only be undertaken by or in consultation with a qualified healthcare professional. Further, confirmatory or diagnostic testing may be needed for final diagnosis of any condition. Cordlife and its testing partner recommend that non-directive genetic counselling and guidance should always be provided to patients prior to undertaking any genetic testing and when reviewing results with the patient. Accuracy of genetic testing may be affected by certain clinical factors. Therefore, test results should always be interpreted in the context of other clinical and family information of the patient. Informed consent should always be obtained from the patient prior to testing.
