1st trimester screening...

Sara

I go in tomorrow at 13 weeks for my first trimester screen! I had to be referred out for it because my doc doesn't do them- from what I understand it's a 2 hr appointment involving 1st genetic counseling and then 2nd an ultrasound and blood test. Does anyone know if this blood test will tell me the gender? I've read so much and I'm not sure if this is the same test as the non invasive one??
