Sneak peek boy result! Contamination?

Micky • 💙 Boy #2 Due October '21!

I went and got my blood drawn at a participating location for Sneak Peek clinical but the lady didn’t clean my arm before injecting the needle. They take it straight from the vein and they do it all the time there but I’m wondering if she didn’t sterilize it am I at risk for contamination and false positive boy result? We are so excited it came back boy but I’m worried it might be false!!
