But the ultrasound that was done at 10 weeks is technically too early to check fluid behind the babies neck so theres a chance things look better on Monday. Thanks, that is really interesting about the mosaic DS.

In response to the increasing availability of the NIPT test, England's Care Quality Commission started carrying out inspections of clinics and hospitals in England - Health Improvement Scotland has also said it currently regulates two services which offer pre-natal testing, In a statement, the CQC says: "We expect providers of NIPTs to ensure that women fully understand the procedure, know that it is not a diagnostic test, are informed about the possible outcomes, and that appropriate support is made available when delivering the test results. The advertise a very low false positive rating but don't mention the false negatives. I feel like it doesn't help that I suffered really bad last year with health anxiety after a scare.

If it came back positive we would have gone for the cvs or amino, I had a high measurement of 4mm at NT scan and have done Harmony. Thank you for those figures I was just told Nipt came back low risk but "it is only a screening test and false negatives can happen and you can still have the amnio if you want" I was never reassured that nipt is really accurate.

Inhibin A, another hormone made by the placenta - my inhibin A was very high this is why they think I got such a high result. Since there are abnormalities on ultrasound, it makes sense to do a CVS.

Ughyes, I'm very aware that the risk of a miscarriage, although slim, is one of the drawbacks. This limit does not apply to high risk pregnancies.
