Is pre-marital screening done with next-generation sequencing?

Pre-marital screening may include a health history, physical assessment, blood tests, and targeted genetic testing. Next-generation sequencing reads many genetic regions in one laboratory process. It can be useful when a clinician needs to assess a broader group of inherited conditions or when a targeted test does not answer the clinical question. It is not automatically required for every couple.

A sequencing result may be reassuring, may identify carrier status, or may need confirmation and specialist interpretation. Being a carrier usually does not mean that you have the related condition. The result can matter for reproductive planning when both partners carry changes affecting the same inherited disorder.

Ask the screening service which conditions are included, whether testing is targeted or uses a wider sequencing panel, and how results will be explained. Share known family conditions, previous genetic results, and any relationship between the couple that may alter counselling needs. Confirm whether the sample is blood or another specimen and when results are expected.

Read the consent information before providing a sample. It should explain possible findings, limits of the test, privacy arrangements, and whether an uncertain result can occur. If a result suggests carrier status or an inherited condition, arrange genetic counselling before making pregnancy decisions.

Seek medical advice before testing if a close relative has an inherited disorder, unexplained childhood illness, repeated pregnancy loss, or a known genetic result. Promptly discuss any abnormal or uncertain report with the clinician who ordered it rather than interpreting it from the laboratory wording alone. A genetics professional can explain whether another test is needed and what the finding could mean for future children.

Which conditions are covered by this screening? Why is this test method suitable for us? What happens if one or both partners are carriers? Will we receive genetic counselling if the result is unclear?
