Non-invasive prenatal testing (NIPT) may be performed after the 10th week of gestation, through a simple blood draw from the mother, to study the genetic material of the fetus. The Fetal Medicine Department offers the option of selecting among the most reliable NIPT methods internationally.   Depending on the test you choose, it may detect:  chromosomal anomalies (T21, T18, T13) sex chromosome aneuploidies (Turner syndrome, Klinefelter syndrome, Triple X syndrome, Jacobs syndrome, XXYY syndrome) microdeletion syndrome (DiGeorge syndrome, 1p36 deletion syndrome, Cri-du-Chat syndrome, Prader Willi syndrome, Angelman syndrome, 22q11.2 deletion syndrome, Smith-Magenis syndrome, Wolf-Hirschhorn syndrome)  50 single-gene disorders (a mouth swab is required from the biological father) If the result is positive, invasive testing is recommended with chorionic villus sampling or amniocentesis to confirm the diagnosis.  Please contact the Department secretary for detailed information about the options and limitations of non-invasive genetic testing.
