How accurate is the NIPT test for Turner syndrome?
NIPT can also be used to detect other fetal genetic diseases, such as fetal sex chromosome aneuploidy (7). In our study, the total positive predictive value (PPV) of NIPT was 54.54%, which was 29.41% for Turner syndrome, 77.78% for 47,XXY, and 100% for 47,XXX and 47,XYY (7).

How common is Turner syndrome in pregnancy?
While Turner syndrome is not common (about 1 in 2500 live female births), approximately 1 to 2% of all embryos have Turner syndrome – but 99% of these miscarry, usually during the first trimester. Turner syndrome may cause up to 10% of all first trimester miscarriages.
Why would someone get tested for Turner syndrome?
A diagnosis of Turner syndrome may be suspected when there are a number of typical physical features observed such as webbed neck, a broad chest and widely spaced nipples. Sometimes diagnosis is made at birth because of heart problems, an unusually wide neck or swelling of the hands and feet.
Should you abort a baby with Turner syndrome?
Nine studies (47.4%)8,9,10,18,20,23,27,28,29 indicated that parents with a Turner syndrome-affected fetus would be more likely to terminate the pregnancy, with an average termination rate of 76% (range: 33–100%).
Who is most likely to get Turner syndrome?
Turner syndrome is a genetic condition found in females only. It affects about 1 in every 2,500 girls. Girls who have this condition usually are shorter than average and infertile due to early loss of ovarian function.
