About 2 weeks ago I got blood drawn for Informaseq test. It's a chromosome test that will tell if there is any chromosomal defects as well as the baby's gender. A week later the test results comeback saying there was not enough fetal DNA to determine anything. I went back in and had more blood drawn. I asked at the time if this result was common and the nurse said she had only seen it one other time the whole time she had been a nurse. She more blood was taken and I got the second test results back today. SAME RESULT!  People can have this test done as early as 8 weeks and I was 12 and 13 weeks when they draw blood. Just frustrated and waiting for a call back from the doctor.
