When is pre-marital screening recommended for thalassaemia carrier?

A carrier usually has one altered haemoglobin gene and may have no symptoms or mild anaemia. The result does not mean that you have thalassaemia disease. If both partners carry a relevant trait, a future child may inherit a more serious form, so genetic counselling can explain the possible combinations without assuming an outcome.

Arrange testing early, ideally before conception, and take any previous blood counts or family records to the appointment. If one result suggests a trait, the other partner may need assessment. Ask whether confirmatory haemoglobin testing and counselling are appropriate, and discuss prenatal or fertility options only after the results are understood.

Book a clinical review if testing shows a carrier state, unexplained anaemia, or a family history of severe thalassaemia. Seek urgent care for chest pain, severe breathlessness, fainting, or marked weakness; these symptoms need assessment regardless of a screening result.

Ask which test is being offered, whether your partner should be tested, what the result says about inheritance, and when a genetic counsellor should join the discussion.
