When is pre-marital screening recommended for genetic risk in related couples?

Biological relatives may share gene changes passed through a family. A family history of repeated childhood illness, developmental differences, early medical problems or a known inherited disorder can make genetic counselling particularly useful. Screening does not predict every condition; it helps clarify which risks warrant further discussion.

Arrange a pre-marital appointment early enough to review both family histories and allow time for follow-up. Bring known diagnoses and previous test reports if available. A clinician may suggest blood tests, targeted testing or referral to genetic counselling, depending on the family pattern and ancestry.

Seek genetic counselling before testing if a relative has a confirmed inherited condition, several relatives have similar unexplained problems, or a previous pregnancy or child was affected. Specialist guidance can explain results and reproductive options without treating a screening result as a diagnosis.

Ask which relatives and diagnoses matter, whether both partners need testing, what a carrier result would mean, and how results could guide future pregnancy planning.
