Noninvasive Prenatal Test, NACE

NACE is a non-invasive, clinically validated prenatal test for the detection of abnormalities of chromosomes 21, 18 and 13 (Down, Edwards and Patau syndromes).

It detects the most common abnormalities of the X and Y sex chromosomes as well.

To perform the test, it’s sufficient to take a small sample of blood from the arm, as in any other blood test. NACE uses the latest technology in sequencing, analizing fetal DNA to maternal DNA to detect certain abnormalities with great precision and reliability.

Indicated for those women with a high-risk index for chromosomal abnormalities after first trimester screening, for previous pregnancies with Down’s syndrome, or for detection of suspicious alterations on ultrasound scans.

The NACE test can also be performed on women whose gestation has been achieved through in vitro fertilization techniques, including egg donation gestations.

The non-invasive prenatal NACE test is valid in cases of single and twin pregnancies.

For single or twin pregnancies. 

Detection of fetal aneuploidies of chromosomes 13, 18, 21.

Single pregnancies: includes aneuploidies for sex chromosomes and fetal sex.

Twin pregnancies: does NOT include aneuploidies for sex chromosomes, and only reports the presence or absence of a Y chromosome.

Extended NACE Test 24 (For single pregnancy)

Detection of fetal auneuploidies in all chromosomes: aneuploidies for the 22 pairs of somatic chromosomes (autosomes) and the sex chromosomes (X and Y)

Fetal sex is reported.

Panel of microdeletions (Syndromes of:  DiGeorge, Angelman, Prader-Willi, 1p36 deletion, Wolf-Hirschhorn and Cri-du-chat.
