Sneak peak result at 13 weeks input

So I did a sneak peek at a lab. The phlebotomist drew blood from my arm and sent it off and got results for boy. I’ve read some come back incorrect so I’ve scheduled a gender ultrasound with a private company. Wondering how many have gotten an incorrect result. I need to add my nipt test keep coming back inconclusive through Natera so I’m not seeing a high risk till 3 weeks from now but I have special family coming in to town in a week we want to do a small gender reveal but scared our result might be wrong from sneek peak after reading many false results:/
