Is NIPT done with next-generation sequencing?

During pregnancy, a blood sample contains cell-free DNA from the placenta alongside the pregnant person’s DNA. A laboratory extracts and analyses these small fragments. Next-generation sequencing is one laboratory method that reads many DNA fragments in parallel and uses their patterns to screen for selected chromosome differences. NIPT is a screening test, not a diagnostic test. A higher-chance result does not prove that a condition is present, and a lower-chance result cannot identify every genetic or structural condition. The exact conditions examined depend on the laboratory’s test panel.

Ask which chromosome conditions and sex-chromosome findings are included, when testing can be done, and how long results may take. Discuss whether the result could affect decisions about further testing. If NIPT reports a higher chance, arrange genetic counselling and diagnostic testing such as chorionic villus sampling or amniocentesis before making medical decisions. If the laboratory cannot issue a result, ask whether a repeat sample or another assessment is appropriate. Share your pregnancy dates, ultrasound findings and any assisted-conception details with the clinician.

NIPT is a blood test and does not usually require urgent aftercare. Contact the testing service if your result is delayed, unclear or marked as no result so you can understand the next step. Seek prompt pregnancy care for vaginal bleeding, severe abdominal pain, fluid leakage, fainting or any sudden concern about your wellbeing; these symptoms need assessment independently of an NIPT result.

Which conditions does this NIPT screen for? What does a higher-chance, lower-chance or no-result report mean? What diagnostic test would confirm a finding? Who can explain the result with me?
