Just curious . Blood gender test

Carina

So at 10 weeks I got the blood test done for genetic testing and they also did the one for the gender ( not sure what it’s actually called) . I’m 24 weeks pregnant now and haven’t had my anatomy scan yet ( due to moving and them being over booked) . Since this would be our 3rd girl , my husband still hopes , that it maybe could be a boy . So I was just wondering. People that actually got it done at the doctors, instead of the home test , how accurate was your result ?
