There are four types of tests: two non-invasive (involving no needle) and two invasive (involving a needle). Non-invasive testing involves an ultrasound scan and blood sample taken from the patient’s arm, and these two options are either NIPT for fetal DNA or else the combined first trimester nuchal translucency scan with another blood test.
Invasive testing can be either a CVS (needle placed into the uterus and placenta) or amniocentesis (needle placed into the uterus and amniotic fluid). These invasive tests are performed in the Rotunda Hospital Fetal Assessment Unit.
Screening and Diagnostic Test Accuracy
Non Invasive Prenatal Testing (NIPT)
The Non-Invasive Prenatal Test (NIPT) is a new screening test that helps us to identify if your baby is likely to have a chromosomal condition, for example, Down syndrome, (Trisomy 21), Edwards syndrome (Trisomy 18) or Patau syndrome (Trisomy 13). The blood test can be performed from 10 weeks of pregnancy onwards.
Invasive / Diagnostic
Chorionic Villus Sampling (CVS)
Chorionic villus sampling (CVS) is a test where a small sample of tissue is taken from your baby’s placenta, which is tested for chromosomal or genetic abnormalities. The test is performed between 10 weeks and 14 weeks gestation.
This test carries a small risk of less than 1/100 that you could miscarry your pregnancy.
Amniocentesis involves inserting a fine needle into the mother’s abdomen to take a sample of the amniotic fluid from around your baby, this is sent to a laboratory for testing.
This test carries a small risk of less than 1/1,000 that you could miscarry your pregnancy.
