What to expect from pre-marital screening for sickle cell carrier status

The appointment may include questions about your health and family background before blood is taken. Testing looks for inherited haemoglobin changes associated with sickle cell conditions. A carrier result does not mean that you have sickle cell disease, but it is relevant when both partners are tested.

A result may show that you are not identified as a carrier, that you carry a sickle haemoglobin gene, or that further testing is needed to clarify the finding. Results are interpreted alongside your partner’s result because each biological parent contributes genetic material to a child.

If both partners carry a relevant gene change, a clinician or genetic counsellor can explain the possible inheritance patterns and discuss available reproductive options. Bring the written result to that conversation, especially if testing was performed in another country or at a different laboratory.

Arrange screening for both partners if this has not already happened, and ask when and how the report will be released. Keep a copy of each report. Do not make reproductive decisions from a brief label such as carrier or normal without reviewing the full interpretation with a qualified clinician.

If a result is unclear, follow the recommended confirmatory test before treating it as final. A clinician may review the blood findings, your family history, and any previous haemoglobin testing. You can read more about the service in [Pre-marital Screening](/treatments/diagnostics-and-imaging/pre-marital-screening/).

Screening itself is generally arranged as a planned appointment rather than an emergency visit. Contact the screening service if you have not received a result within the timeframe they gave you, if names or identifying details on the report are wrong, or if the report says that another test is required.

Seek urgent medical help for severe breathlessness, chest pain, fainting, sudden weakness, or severe pain, whether or not you are known to carry a sickle haemoglobin gene. These symptoms need prompt assessment and should not be explained away by a screening result.

Ask: What exactly does my report show? Does my partner need testing? Is confirmatory testing recommended? Could this result affect pregnancy planning? Should we speak with a genetic counsellor, and which records should we bring?
