New Chromosomal Alterations Prenatal Test in the mother’s blood
With a simple blood sample from the mother, some fetal DNA is obtained and can be identify and quantify through an advanced technological process: massively parallel sequence. Finally, a statistical analysis of suffering any of the anomalies mentioned is obtained.
The sensibility or reliability of the test is very high, as it has screening rates higher than 99% with false positives lower than 0,1%.Therefore, the great difference with respect to the routine tests used nowadays, is a clear reduction, of up to five times, of the false positive results that to perform unnecessary invasive tests.
Is not useful in multiple pregnancies but it can be applied in all other pregnancies achieved after assisted reproduction treatments, included the egg donation ones.
This prevents the performance of many amniocenteses allowing a precise risk evaluation of the trisomy responsible of the majority of chromosomal anomalies.
