If the NIPT shows that there is a high chance that the baby has trisomy 21 or 18 or 13 it does not mean that the baby has one of these conditions. If you want to be certain if the baby has one of these conditions you should have CVS or amnio. If the NIPT shows that there is a low chance (less than 1 in 10,000) that the baby has trisomy 21 or 18 or 13 it is unlikely that the baby has one of these conditions.
The results from the test will generally be available within 4 business days and we will notify you as soon as we receive them by phone and email/letter. In about 2% of cases, the test does not give a result. This is due to technical problems with the analysis of the sample and does not suggest that there is a problem with the baby. If you want, you can have the test repeated (at no cost) and there is a 65% chance that the test will give a result.
The NIPT does not provide information on other rare chromosomal abnormalities. If the scan at 11-13 weeks (about 3 months) shows a high nuchal translucency (more than 3.5 mm) or major defects, such as exomphalos, holoprosencephaly, heart abnormalities, or megacrysts, the chance for some rare chromosomal conditions may be high. In such cases, you may choose to have CVS or amnio.
The NIPT does not provide information on physical defects, such as heart or brain abnormalities spina bifida, or fetal growth. It is therefore advisable that you still have ultrasound scans at 11-13 weeks (about 3 months) and at 20-22 weeks (about 5 months) to examine the fetal anatomy and at 30-32 weeks (about 7 and a half months) to examine the fetal growth.
