Panorama !!!!!! HELPPP

Ok ladies I need you're help ! My sister in law is planning a gender reveal for me on January 22nd which is next Sunday. I went to go get the panorama blood test today and they said they only do it during the week I have to wait till Monday. That's cutting it super close I'm afraid I will not be able to give her results in time for the party!
So I wanna know if anyone has had this testing and how long did it take. I'm wondering if I should cancel
I also found the website sneekpeaktesting.com and was thinking about buying that just incase but I don't know how accurate it is, so if anyone's done that too please provide feedback!
