Anyone doing this?

I had my genetic testing done at 10 weeks and everything came back good. Now last week when I had my 12 week appointment they told me that there is a second part to it called the neural tube defect test also known as “MSAFP test” anyway, has anyone or is anyone planning to do this test? They say this test just causes more stress because it gives more false positives than any other test. Just wondering if it’s even worth doing?
