What to expect from premarital screening for thalassaemia

The assessment may include a blood count and haemoglobin analysis. Thalassaemia trait can be present in someone who feels healthy; it is different from thalassaemia disease, which can affect haemoglobin production more substantially. Screening findings may overlap with other causes of small red blood cells, so the clinician may recommend confirmation.

When both partners carry a thalassaemia-related gene change, a future child may inherit a more serious form. Counselling explains the specific pattern involved and avoids treating a carrier result as a diagnosis of illness.

Bring previous blood counts, tell the service about relatives with thalassaemia, and complete any follow-up test requested. Discuss the findings with both partners and ask for a written summary if the terminology is unfamiliar.

Before pregnancy, ask about genetic counselling and the reproductive options relevant to your results. Do not start iron supplements solely because the blood count is low; iron deficiency and thalassaemia trait require different assessments.

Arrange routine follow-up for an abnormal or uncertain result. Seek prompt care for chest pain, severe breathlessness, fainting, or profound weakness. These symptoms need assessment regardless of a screening result and should not be attributed to thalassaemia trait without examination.

Ask whether the result indicates trait, disease, iron deficiency, or another finding; whether your partner needs testing; and whether a specialist or genetic counsellor should review the report. Ask how the result affects pregnancy planning.
