Non-Invasive test (results availables in 6-9 days)

Our network of partner laboratories no longer offer this test. They have expanded the test to rule out a wider range of syndromes and thus rule out a wider range of syndromes. For more information, click on "See more".

Why is this analysis useful for me?

  • It allows you to detect the presence of genetic markers in the fetus of Down syndromes at an early stage of pregnancy.
  • You can avoid invasive tests like amniocentesis, which are uncomfortable and dangerous for both, mother and baby.
  • Allows you to take decisions based on the current legislation.

Who should I have this test?

  • It will give you peace of mind about your pregnancy from week 10, superior accuracy (less than 0.1% false positives).
  • If you had previous pregnancies with the presence of trisomies.
  • If it is your first pregnancy and you are over 35 years old.
  • If you have fetal ultrasound abnormalities.
  • If you have a high hereditary risk of fetal aneuploidies.

What is a non-invasive prenatal test (NIPT)?

  • The Non-invasive Prenatal Test is a maternal blood test that detects the main chromosomal alterations of the baby, avoiding the possible risks of amniocentesis.
  • When you are pregnant, your blood contains fragments of your child's DNA. This test has greater accuracy and a lower rate of false positives; compared to traditional invasive tests.

What technology does it use?

  • qNIPT determines differences between methylation patterns in specific maternal and foetal DNA genetic regions. Certain genetic regions of the maternal DNA are hypometilated while the same regions are hypermetilated in the case of foetal DNA. These specific metilated genetic regions are used as DNA biomarkers for detection of the trisomy 21 on the fetus.
  • It is a highly precise quantification technique with a sensitivity and specificity greater than 99%.
  • The test is validated for use in single and twin pregnancies and IVF (own egg or egg donation).
