WHAT IS A PRENATAL DIAGNOSTIC TEST?
Prenatal diagnostic testing is used to determine whether the baby has a chromosomal abnormality. The most common types of prenatal diagnostic tests available are Chorionic Villus Sampling (often simply called "CVS") and Amniocentesis (often simply called "amnio").These tests involve putting a needle into either the placenta or amniotic sac.
They are associated with an increased risk of miscarriage (1%). These tests are usually performed only in certain situations.Prenatal diagnostic testing (CVS and amniocentesis) provides a definitive (100%) diagnosis of a chromosome abnormality.
WHAT IS NON-INVASIVE PRENATAL TESTING?
Non-invasive prenatal testing (NIPT), also known as non-invasive prenatal diagnosis (NIPD), is a screening method for detecting certain specific chromosomal abnormalities in a developing baby.
- Non-invasive Prenatal Testing (Free Fetal DNA in Maternal Blood) is a blood test that determines the risk of fetal trisomies like Trisomy 21 (Down Syndrome), 18 (Edward Syndrome) and 13 ( Patau Syndrome). It also includes and optional analysis of fetal sex and sex chromosomes (X,Y) conditions but does not rule out all fetal abnormalities.
- The accuracy of the test is about 99% and the turnaround time is 10 days to 2 weeks.
- Normal chromosomes testing results do not guarantee that all genetic testing have been excluded or normal.
- Abnormalities finding will be explained to me. In rare cases of positive (abnormal) result, Invasive test will be indicated.
