NON-INVASIVE PRENATAL SCREENING.
Non invasive prenatal screening is a test done during pregnancy to determine the likelihood of a fetus having a chromosomal disorder. It is a safe procedure as the mothers’s blood is taken intravenously and taken to the lab for a**lysis. The mother’s DNA contains free floating cell free DNA from the fetus and as such makes it easy for detection. It is however important to note that NIPT doesn’t screen for all chromosomal disorders and it does not diagnose a condition. NIPT mainly determines the likelihood of disorders such as Down’s syndrome, Edward’s syndrome, Patav‘s syndrome and s*x affecting chromosomal disorders such as sickle cell disease. It is recommended to do an NIPT test if you already have a child with chromosomal abnormalities, if an ultrasound showed that the fetus may have an abnormality and have had earlier screening tests that suggest a potential problem. NIPT should be done as early as 10 weeks of pregnancy all through delivery and it is 99% accurate for testing Down’s syndrome. NIPT testing is optional and incase of any concerns, your medical healthcare provider should be able to advice you on prenatal genetic test and help you make an informed decision.
