Are you talking about Intelligender???
I did this test at 10 weeks - it came back boy.
I also did another expensive gender test where I had to send another sample overseas and it cost me $275. - it also said boy.
They were WRONG.- all ultrsounds have shown I'm having a girl.
They were a waste of money and I regret spending the money on something that wasnt even close to 100% accurate. There have been alot of threads about these types of test and you'll see they have no greater odds than 50/50.
