This article seems a bit deceptive. We are going through NIPT soon and our doctor went over false positive and false negative rates for the common screens. Our doctor has pointed out some of the screens (esp for rare conditions) are not that accurate. The only procedure with high accuracy, amniocentesis, has a slight risk of miscarriage (our provider quoted 0.3% ) so its still statistically better to take NIPT and then only consider amniocentesis with a positive result since there is no risk from NIPT.

You are supposed to treat a positive on NIPT as “there’s a chance your baby has this, need a more accurate procedure to confirm”.

It sounds like their ob gyn wasn’t able to explain results to them or they didn’t understand the probabilities. To be fair our provider didn’t even suggest tests for the disorders in the article, probably because of the false positive rates and rarity. Sounds like these extra screens shouldn’t be offered.
