Carrier screening is a test to see if you are a “carrier” of a gene for a specific genetic disorder. A “carrier” is a person who has the gene for a specific genetic disorder, but does not show symptoms of the disorder.

This test is mainly used for the following purposes

Family planning: couples of childbearing age are tested to reduce the risk of passing on a genetic disorder to their children. If two people are carriers of the same genetic disorder, their children are more likely to inherit the disorder, and further decisions can be made based on this information.

Genetic risk assessment: Determines whether an individual is a carrier for a specific genetic condition, so that they can be proactive in knowing their risk of developing the condition.

Currently, 3billion’s carrier screening tests are designed to determine the likelihood of developing a specific condition in family members at high risk for a genetic disorder with a previous case of the condition, and are not performed in healthy individuals.
