What to expect from premarital screening for sickle cell disease

Testing looks for haemoglobin patterns associated with sickle cell disease and for carrier status. A carrier may feel well and does not have the disease, but can pass the altered gene to a child. A result suggesting sickle cell disease or another haemoglobin condition needs clinical confirmation and an explanation in plain language.

If both partners carry a relevant gene change, a clinician or genetic counsellor can explain possible outcomes for future children. Screening does not predict a child's exact health or replace an assessment of current symptoms.

Attend the appointment together when possible, bring previous blood reports, and tell the clinician about known family haemoglobin disorders. Ask when results will be ready and how they will be delivered. If a result is unclear, arrange the recommended confirmatory test rather than interpreting a screening label alone.

Use the consultation to discuss reproductive choices, pregnancy planning, and whether relatives may benefit from information. Results are personal medical information; ask how they are recorded and shared.

Screening itself is not an emergency. Seek prompt medical care for severe pain, trouble breathing, fainting, marked weakness, or fever, especially if you already have a haemoglobin disorder. Contact the screening service if you develop a reaction after blood collection or cannot access a result that needs follow-up.

Ask which tests are being performed, whether you are a carrier, whether confirmation is needed, and what the findings could mean for children. You can also ask who will provide genetic counselling and what information your partner should receive.
