Invitae Genetic Testing Experiences?

St

Has anyone used Invitae through their provider? Did your gender results or other chromosomal results end up being accurate? I did the blood work in my provider’s office today since my husband is over 35, I just wasn’t sure if the company itself has had issues with contamination? And how long did it generally take for your results to get back with everything? My provider said generally 4-7 days, but to ask about other people’s experiences if I felt the need to since I hadn’t ever heard of them. Thank you in advance!🖤
