Panarama testing?!

Jennalee
Hi everyone! I went to my 12 week check up for my little one and was amazed by how big he or she is getting already! This is my 3rd baby and while at my visit my doctor asked me if I'd be interested in the panorama testing for genetic testing and also you're able to find out the gender? I am so new to this I've actually never even heard of it I'm so used to having my 20 week anatomy scan...I was wondering if anyone could give me a little insight on it - most importantly hoping for a healthy child but also curious on the accuracy of gender with these tests?! Thanks ladies!!
