Interpretation of the results:

Low risk: confirms with 99% certainty that the fetus does not present the analysed syndromes, although it does not completely rule out other abnormalities.

High risk: it is essential to consult your gynaecologist. There is a minimal possibility of a false-positive result; therefore, confirmation requires a definitive diagnostic test, such as amniocentesis.

It is indicated for twin pregnancies through egg donation, pregnancies with a confirmed vanishing twin, and pregnancies following a recent bone marrow transplant.

It can be performed from week 10 of pregnancy. In the case of a vanishing twin, it must be performed from week 16 onwards.

Detects Trisomy 21 (Down Syndrome), Trisomy 18 (Edwards Syndrome), Trisomy 13 (Patau Syndrome) and reports on the presence/absence of the Y chromosome.

No, it is a non-invasive test performed with a maternal blood sample, minimizing any risk to the mother and the fetus.

It offers high accuracy and is non-invasive, providing reassurance in cases of twin pregnancies through egg donation or pregnancies with a vanishing twin that are not covered by the standard NIPT.

If the result indicates "High risk", it is essential to consult your gynaecologist. A high-risk result carries a minimal possibility of a false-positive result; therefore, confirmation requires a diagnostic procedure such as amniocentesis.
