i have paid for the NT screening both times (so about 18 weeks ago & before that 3 years ago). i didn't have to pay at the time i had the blood taken but i did pay when i had the u/s done & then a bill from the RCH (think it's the murdoch research institute that does the results?) for the pathology. the scan cost me around $200 & the pathology was about $120 from memory.
