The non-invasive prenatal test (NIPT) is a prenatal test performed with a simple maternal blood sample. The NIPT allows for the high-precision detection of possible chromosomal abnormalities in the baby, such as Patau Syndrome (trisomy 13), Edwards Syndrome (trisomy 18) and Down Syndrome (trisomy 21), among others. It is a safe, non-invasive and risk-free test. The NIPT provides you with crucial information to make informed decisions about the pregnancy and the future of the baby.
At Clínica Magnasalud we use the BBSAFE® Non-Invasive Prenatal Test from Cerba International laboratories. The technology used by this test allows for the non-invasive quantification and sequencing of fetal DNA fragments present in the maternal blood. This test sequences fetal DNA with 99% reliability.
How is a non-invasive prenatal test performed?
The non-invasive prenatal test is very similar to a blood test. The patient comes to our infirmary where a blood sample will be taken. The sample will be sent to our reference laboratory for analysis. Within 4 to 5 working days we will contact the patient to send the report with the results electronically.
Non-invasive twin prenatal test
This test is also suitable for twin pregnancies. In this case, you will have to wait until the 12th week of pregnancy.

Frequently asked questions
Can I take the test if I am pregnant in vitro?
Yes, any pregnant woman, oocyte recipient or treated by in vitro fertilization is suitable for this test.
In which week can I take a prenatal test?
The NIPT can be done from week 10 of pregnancy. If you require a non-invasive twin prenatal test it can be done from week 12.
Do I have to fast to take a non-invasive prenatal test?
It is not necessary, it does not affect the test results.
Differences between non-invasive prenatal testing and amniocentesis
Amniocentesis is an invasive process that requires inserting a needle into the placenta to extract a sample of amniotic fluid. It is performed between weeks 14 and 18 of pregnancy and is a procedure that lasts about 30 minutes. Amniocentesis is normally used when the non-invasive prenatal test is positive and a second test is needed to confirm the result.
The non-invasive prenatal test, as its name indicates, is a non-invasive procedure that allows the baby’s DNA to be studied from a blood sample from the mother. It is a much faster, more comfortable and safer procedure. For this reason, it is preferred as a first option over amniocentesis.
