Who can have the test?

Home > Medical Issues  > Obstetrical  > Detection of Fetal DNA in maternal blood > Who can have the test?

The test is suitable for any woman who has had an ultrasound scan to confirm that her pregnancy is singleton, that the fetus is alive, and that the fetal length is equivalent to a gestation of 10 weeks or more. Also it can now be requested for IVF singleton pregnancies including self donor, unrelated egg donor and surrogate pregnancies. In such cases the age of the donor should be given to allow an accurate risk score. The test is not intended for use in cases of multiple pregnancies. The results will be ready in approximately two weeks, at which time most women can have their 12-week scan for a detailed examination of the fetal anatomy, including measurement of nuchal translucency, nasal bone and other important factors. In this visit, patients can discuss the DNA and ultrasound results with their obstetricians. On the basis of the NIPT result and the ultrasound findings, a patient can decide whether or not she wants to have an invasive procedure (for example, CVS or amniocentesis).
