In humans, each cell normally contains 23 pairs of chromosomes, the last pair of which determines sex. When an individual has more than two chromosomes instead of a pair, the abnormal condition is called trisomy.

What is Verifi Plus prenatal Test?

The Verifi Plus prenatal test is the option for singleton pregnancies to provide more information about trisomies for all chromosomes as well as clinically significant microdeletions.

What kind of conditions can the Verifi prenatal test detect?

The Verifi prenatal test gives you information about whether there may be extra copies (trisomy) of chromosomes 21 (Down syndrome), 18 (Edwards syndrome) and 13 (Patau syndrome).

If the sex chromosome aneuploidies option is chosen, the Verifi prenatal test can also look for sex chromosome abnormalities, such as Turner syndrome, Triple X, Klinefelter syndrome and Jacobs syndrome. In addition, prenatal screening for Verifi Plus can also help detect delusional syndromes that Triple Tests cannot identify, such as DiGeorge Syndrome, Deleting Syndrome, Angelman Syndrome, Prader Willi Syndrome, Cri-Du-ChatSyndrome, Wolf-Hirschhorn syndrome. Therefore, screening for chromosomal abnormalities should be performed as soon as possible to build a healthy future.

Advantages of non-invasive prenatal screening:

  • Safety: Non-invasive blood tests (no Aniocentesis, no Chorionic Villus Sampling-CVS) and no risk of miscarriage, safe for mothers and babies.
  • Accuracy: Has the lowest test failure in its class (0.1%)—which means there is no need for additional blood draws. Proven superiority to traditional screening methods for the screening of common fetal aneuploidies, with reduced false positive rates (increased specificity) and increased positive predictive values (PPV)
  • Convenience: a simple, single blood draw (7-10 ml) from your arm—just 1 tube of blood is all that’s needed and can be drawn conveniently as early as 10 weeks.
