panorama testing

Christina
Has anyone else had panorama blood testing done and found out the gender? I am due August 29th and had the testing done back in February. It came back that I'm having a boy. We are doing an anatomy scan at 20 weeks. Has anyone experienced a wrong gender with the panorama testing? I looked at their site (of course it says it's super accurate). Just curious. I've always wanted a boy (I have a girl already) but I'll be happy either way.
