Does pre-marital screening treat genetic risk in related couples?

Pre-marital screening uses health checks and selected tests to identify conditions or carrier states that may matter before marriage or pregnancy. When couples are biologically related, a family history review and genetic counselling can add context about inherited conditions. A screening result is not a treatment and may not detect every possible inherited condition.

A counsellor can explain what a result means for each partner, whether more testing is appropriate, and what options may be available before pregnancy. Results should be discussed privately and understood by both people.

Arrange screening early enough to allow time for results and follow-up. Bring details of known family conditions, childhood illnesses, unexplained deaths, and previous genetic test results. If either partner has an abnormal result or a strong family history, request genetic counselling rather than trying to interpret the report alone.

Seek genetics advice before pregnancy when a family member has an inherited condition, several relatives have a similar diagnosis, a previous child was affected, or screening identifies a carrier state. Couples planning pregnancy can ask about diagnostic options and reproductive choices without assuming that a result predicts a certain outcome.

Ask: Which tests are included in our screening? What does each result mean for us? Should we see a genetic counsellor? Is further testing needed before pregnancy? How will our information and results be handled?
