NIPT testing

So my doctor only offers a brochure for the natera panorama test and my insurance doesn’t cover it and it would cost me $300 to have it done. I know that’s not the only NIPT available and I was wondering if there’s any other place/test that is more affordable? Is anyone familiar with the process? I know labcorp offers testing but idk if I would need a doctor order or if it would be very expensive. Any advice or help with this would be great. Thank you!
