So, im so confused right now. I got my results on my 2nd trimester quad screening and the levels were high and now i need a level 2 ultrasound to check for spinal bifada. how accurate are these tests because im starting to freak out a little bit, i had a daughter 9 years ago with spinal bifada that passed away and im just nervous that they are going to find something. i hear the tests can give false positives but i dont know what percentage that is. if anyone has had this happen to them and there babies were fine or have more information on how accurate these tets are i would greatly appreciate it, i just need some piece of mind.
