What do the results mean?
If your results were negative, it's unlikely that your baby has Down syndrome or another trisomy disorder. If your results were positive, it means there is an increased risk that your baby has one of these disorders. But it can't tell you for sure if your baby is affected. For a more confirmed diagnosis you'll need other tests, such as amniocentesis and chorionic villus sampling (CVS). These tests are usually very safe procedures, but they do have a slight risk of causing a miscarriage.
If you have questions about your results, talk to your health care provider and/or a genetic counselor.Learn more about laboratory tests, reference ranges, and understanding results.
