Gender accuracy from blood test

[kitcat2015]

I'm 33 weeks with my second baby.  Early on, I had the genetic blood test done for risk assessment purposes.  The blood test indicated that I would be having a girl.  My 2 ultrasounds indicated the same.  What is the accuracy of these tests?  I'm confident that I'm having a girl, but my mom is starting to swear up and down that it's a boy based on the shape of my belly!  What are the chances that a test and 2 ultrasounds are wrong?  Lol.

I would say a blood test and ultrasound is more trustworthy than the way you carry, which doesn't mean anything when it comes to the gender. Those blood tests check bubs dna so would be pretty spot on.

I had the same test done the blood test an all my ultrasounds said boy. An I had a boy!  The blood test is extremely accurate it separates you from your baby
