The prenatal maternal blood genetic test is a non-invasive analysis that can be performed from the 10th week of gestation.
It allows us to use a maternal blood sample to detect genetic alterations in the foetus and so it is safe both for the foetus and the mother.
The test can be performed both in twin pregnancies and in pregnancies conceived through assisted reproduction techniques with gamete donation.

Who is it for?
When is it recommended?
This test is recommended for any pregnant woman given that its sensitivity to detect chromosomal alterations is much higher than that of routine screening tests.
Secure Natal is especially recommended for patients aged over 35 years or as an altered combined screening, and in patients with a history of genetic alterations or that have had recurrent miscarriages.
The basic test evaluates the risk of foetal trisomy for chromosomes 21 (Down syndrome), 18 (Edwards syndrome), and 13 (Patau syndrome) with a detection accuracy greater than 99%.
In the extended test, aneuploidies of all the chromosomes, microdeletions, and microduplications are studied with a resolution of up to 5 Mb and DiGeorge syndrome caused by deletion is examined with a resolution of 3 Mb.
