NIPT blood + NT scan

Has anyone had just the NT scan and NOT the nipt/NT bloods?

I had my NT scan today at 13+3. The sonographer wasn’t concerned about anything. All measurements looked great. I went to have my NIPT blood test and I was going to be charged $525 AUD. 😳 So I decided not to get the blood test.

This is my 4th baby and I don’t remember any blood tests costing that! So I’m wondering if anyone has just done the NT scan without the blood tests?
