It is a non-invasive blood test wherein free-floating foetal DNA is extracted from the mother’s blood and assessed to check for the presence of any chromosomal aneuploidies or anomalies which may lead to the risk of your baby having genetic conditions such as Down’s Syndrome, Edwards, Syndrome or Patau’s syndrome. It is an accurate and highly sensitive test, however it a screening test. Incase the NIPS test is high risk for a genetic condition, an invasive test such as chorionic villus sampling (CVS) or Amniocentesis may need to be done to procure a sample and tested using karyotype to confirm the presence of such a condition in the growing foetus.
This test requires a healthcare professional to draw venous blood from your upper arm using a sterile needle. It is then collected in a special NIPS tube and sent to the laboratory for testing.
