i am looking at privately having the nipt. age 40 and currently 9 weeks+6. obviously foremost want to know about the chances of health problems. have read loads of posts on here about accuracy of results and great outcomes for everybody, which puts my mind at rest. but very interested in finding out the gender. are the tests at just 10 weeks really accurate with the correct sex. i have also heard that a lady with an over weight BMI can effect results, has anyone heard of this and if its connected to the risks or gender part of the test. thanks for any info xxx
