Non-invasive Prenatal Testing (NIPT)

Non-Invasive Prenatal Testing (NIPT)


NIPT is an advanced and powerful risk assessment tool of detecting serious diseases which are caused by aneuploidy of chromosome 13, 18 and 21. We are able to screen out if the fetus will be at high risk to have certain disease as early as 10 weeks of pregnancy using a single blood draw.

It will be more convenient and accurate than traditional serum screening. It also provides us a possibility to know the result earlier than amniotic fluid test.


GGA NIPT can screen chromosome aneuploidies, sex chromosome aneuploidies and common microdeletions as following:

Chromosome Aneuploidies:

  • Trisomy 21 (Down syndrome)
  • Trisomy 18 (Edwards syndrome)
  • Trisomy 13 (Patau syndrome)

Sex Chromosome Aneuploidies:

  • 45,X (Turner syndrome)
  • 47,XXX (Triple X syndrome)
  • 47,XXY (Klinefelter syndrome)
  • 47,XYY syndrome


  • 22q11.2 deletion syndrome (DiGeorge syndrome 1)
  • 1p36 deletion syndrome
  • 2q33.1 deletion syndrome
  • Prader-Willi/Angelman syndrome
  • Cri-du-chat syndrome
  • Langer-Giedion Syndome
