Invasive Prenatal Testing

Ensuring a healthy and successful pregnancy

What is Invasive Prenatal Testing

Invasive prenatal testing is utilized to genetically diagnose a fetus for various conditions. Invasive testing allows for a more definitive diagnosis compared to non-invasive methods such as NIPT (Non-Invasive Prenatal Testing) with a fast turn-around time. Fetal DNA sampling can be collected through:
  •  Chorionic Villus Sampling (CVS) at 11+ weeks of pregnancy
  • Amniocentesis at 14+ weeks of pregnancy

Disorders Tested through Invasive Prenatal Testing

Chromosomal Aneuploidy

This type of testing can detect abnormalities in the number of chromosomes present in the fetus. Viafet can test for aneuploidies for all 24 Chromosomes utilizing our advanced technologies.

Common examples include trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome).

Mutational Status of Familial Diseases

If certain genetic disorders run in a family, invasive prenatal testing can determine whether the fetus has inherited the specific gene mutation associated with the disease- determining whether the fetus is healthy or affected. Viafet can test for any familial genetic mutation.

Examples include cystic fibrosis, sickle cell anemia, or muscular dystrophy.

Indicators of Invasive Prenatal Testing

Invasive prenatal testing is recommended for patients with:

  • a family history of genetic disease.
  • after a patient receives an abnormal prenatal screening test result.
  • If a patient receives an abnormal ultrasound diagnosis and requires a fast turn-around time.
  • Pregnancy in which one of the partners is a carrier of a structural rearrangement.

Why Viafet

  • Achieve swift results with a rapid turnaround time of under 5 days.
  • Can detect both chromosomal aneuploidy and monogenic disorder from a single sample.
  • Can test the fetus of any genetic disorder.
  • Employ the practice of paternity testing consistently to eliminate any possibilities of maternal contamination.
