Who can take this test?
These tests are recommended for women who want to rule out the most commonly detected fetal chromosomal alterations without putting their pregnancy at risk. They are especially recommended for women with a high risk of chromosomal abnormalities after first trimester screening, those with previous Down syndrome pregnancies, or to detect any alterations suspected from ultrasounds.
NACE® and NACE® Extended 24 can also be used by women whose pregnancy was achieved via in vitro fertilization, including gestations resulting from donated oocytes.
The NACE® non-invasive prenatal test is valid in single and twin* gestations and NACE® Extended 24 is validated for single pregnancies.
*In these cases it does not provide information on the gender of the fetuses.
