This is my third pregnancy. I'm 17 weeks and 5 days along. With my first two, I didn't have the quad screen done. This time, since I'm almost 33, I did. The midwife explained to me that it's just a screening and not to panic if the results come back as "elevated risk". Sure enough, one week later and I got a call saying the baby is at an elevated risk for Trisomy 18. The risk ratio is 1 in 15. I know this happens and there's a good chance the baby is okay. But combined with a few other things (I'm measuring slightly larger than I should be, haven't felt the baby kick, have had a nervous feeling this whole pregnancy) I am extremely worried. I'm hormonal as it is and I've spent two days crying, after reading that trisomy 18 is usually fatal.
I was reading that the "false positive" rate for the quad screen for trisomy 18 is .5%, much lower than for trisomy 21.
Has anyone experienced this? I see posts about it but it seems like many people had a much different risk ratio. Mine seems high and I'm worried.
I have to wait a week to get the MaterniT 21 test, and then up to 5 business days for the results and they refuse to move my ultrasound up to check for markers. (It's scheduled for 6/19)
Any advice or sharing your experiences, good or bad, would help. I feel so alone. We waited until 15 weeks to tell our family and I was finally getting really excited. Now I'm a nervous wreck.
