Sorry I don't have that #...maybe you can google and look for it??
I hate to be the bummer about the test but it is soooooooo not accurate. Especially if you have had boys before. I was told I was having my 3rd boy and I had a girl. There is so much on this site about this test. The main point here is that even if you have taken this test, you will still "always wonder" if it was correct...especially if you hear what you don't want to hear. And if you do hear what you want, you will set your self up for a possible let down at the ultrasound. Again...sorry to be such a let down but there is no reliable test other then amnio or CVS to determine gender.....
