NIPT testing

I had my 12 week ultrasound today and I asked about the NIPT testing and they said I had to be 35 years old to get it. I’m 18 and I have a friend who when she was 19 she got the NIPT testing done.

Is it true there’s a age requirement for this?

Edit: I’m 18 and I live in Pennsylvania and I have keystone first as my insurance and they cover pretty much everything
