Couple of thoughts... After talking with one of the founders of Intelligender, I have a tiny bit of insight into there latest formulation. The results for a girl are way more accurate than boy readings. I took the test at 9 1/2 weeks and it said girl. We have just confirmed that we are having a girl. I went on to take three more tests, even dropping off urine at the founder's home, so she could take it into a lab for testing. They were interested in me b/c I am on progesterone suppositories, which has been known to give false boy readings. After my first test, each of the subsequent tests came back as a light light green. This would be read as a boy per their latest package insert, but b/c the results were not "typical boy"... they felt the progesterone was falsely impacting the results and there opinion was always girl for me. You can take a picture of your results if you have questions and email them. They have phenomenal customer service. Another interesting thing she mentioned was taking the test early and recieving a girl result is real convincing. Most early tests (before 10 wks) will yield a boy result. Therefore, b/c I took mine a tad early and received girl... they were confident I was having a girl.
