Non-Invasive Prenatal Test

Non-Invasive Prenatal Test

Trisomies 21, 18, 13 + Monosomy X + Triploidy + Foetal sex + Microdeletion.

What is your test?

Valid for twin pregnancy or for egg donation
  • Trisomy 21. Down S.
  • Trisomy 18. Edwards S.
  • Trisomy 13. Patau S.
  • Monosomy X. Turner S.
  • Foetal sex
  • Triploidy
In a twin pregnancy, it determines:
  • Individual foetal fraction of each dizygotic twin.
  • Foetal sex of each twin.
  • Zygosity of the twins (monozygotes or dizygotes).
  • Possibility of monosomy X in monozygotic twins.
  • 550€
  • Turnaround time: 8 working days (Monday to Friday)** ** In cases of low foetal fraction, the turnaround time may vary
  • Watch video


Technically superior:
Targeted NGS sequencing and analysis of SNPs.

Increased sensitivity in
low foetal fractions.

Gives the individual foetal fraction
of each twin.

Unique in detecting unobserved triploidy
and vanishing twin.

Unique in detecting foetal
and maternal genotype

Unique in identifying
maternal contribution.

Reduces false positives
and negatives.

From week 9
of the pregnancy.

What information does it provide?

High risk

A definitive diagnostic test in amniotic fluid has to be performed to confirm this. Echevarne Laboratory offers a CarioChip® Prenatal test included in the price.

Low risk

It does not rule out the possibility of foetal chromosomal anomaly, although studies made show that it excludes the probability of these syndromes in over 99% of cases.
