Background info: I am 29, this is my first child...
I skipped the 11-14 week testing. After speaking with my husband, we decided to do the 2nd trimester (blood test only, usually done about 16 weeks I believe)... My Dr. scheduled me to come in for the blood test at 15 weeks. I got the call yesterday saying the blood test came back positive with a 1 in 137 chance it could be DS. After a stressful evening, crying, trying to (unsuccessfully) schedule an appointment with a specialist who is on vacation... I finally got a kind call from a Dr. in the same office as the specialist. They let me know that my Dr. should not have done the test before 16 weeks and that we should do it again. She went as far as saying she wants me to do the blood test again now that I'm over 16 weeks and bets it comes back negative.
Has anyone experienced anything like this? I've read there are a lot of false positives out there, but I am a realistic person. I just want the truth, ya know?
Re: Positive result after 2nd trimester screening :(
I know someone who had positive markers for T18 at the first trimester scan. Later testing turned out to be nothing at all. She has a perfectly healthy baby. I'd go to the specialist when you can but take some comfort in what she said about a good possibility of a neg result.
I am really hoping that I am in the same boat as you. I opted out of the NT scan which I now regret and had the quad screening done at 15w2d according to LMP. I think I might have been even earlier based on my first ultra sound and when I ovulated. I got my test results back with a 1 in 82 chance of downs. After during further research I think my test was done to early which I am hoping will make this a false positive.
I immediatly went in for a level 2 ultra sound with a specialist and he found that there were no markers for downs and that my little girl looks perfect. If I were you I would listen to the specialist and get retested and also see if you can get a level 2 ultra sound. After my ultra sound they changed my odds to 1 in 240 (less than half a percent chance). My DH & I decided that we were going to enjoy the rest of this pregnancy and not do any further testing, but it will definetly be in the back of my mind until I have this little girl in my arms. Good luck and I hope that everything turns out perfect with your LO!
A positive just means that you are at higher risk, it does not mean that your baby actually has a problem. However, you may want to consider doing amnio or some further testing to get more definitive results.
I wish you the best of luck!
Thanks everyone- your positive words and similar stories really help, as always.
I am definitely going to do a second round of blood work. I really want a level 2 u/s, but I am not scheduled for one at the specialist. I might ask again, although they said they don't recommend it before 18 weeks.
I have had a few issues now with my OB and am considering switching. What a hassle mid-pregnancy, but may be the right thing for me.
I'd ask again about the Level 2 u/s - I just got my results back yesterday (1 in 110, so also an elevated risk) and my OB pushed to get the level 2 ASAP to get a better idea since I don't want to do an amnio. My appt is scheduled for next Tuesday and I will barely be 17 weeks.
Since you did the NT, the results you got from that test (1:2000) trump the quad test results, which is not as accurate, according to the peri I see. Just fyi.
This. Also a 1 in 167 chance is less than 1%, meaning you have a very slight change that your kid will have Down's.
See, I'm already a HUGE worry wart as it is which is exactly why my husband and I decided to opt out of the testing. There's nothing we can do about it anyways if it came back positive so what was the sense in knowing? We're very "we'll cross that bridge when we get to it" type of people, which is both good and bad, lol
I wish you the best of luck and will keep you and your family in my thoughts. From what I've read there seem to be a lot of false positives out there so I'm sure it's nothing to worry about.
Oh, and finding a new OB sounds like a good idea. It may be a PITA but it would be totally worth it. You need to feel comfortable and trusting and like your doctor. I think that's so important.
Keep us posted!
I've heard of a lot of false positives, too...we aren't doing any screenings particularly for this reason.
Yes there are a ton of false positive results for testing! Even with any other type of test out there from Hepatitis to Influenza, etc........I am a nurse and deal with tons of false positive test reasults for all types of illnesses.
I too had a postive 1st trim. screen. I had the testing done because I was concerned about the baby because I didn't realize I had been prego for over a month and had been taking some kidney medication that is a Category C for pregnancy. So this was one of the tests I wished to have to cover all my bases. Mine was positive for Trisomy 13/18 which is worse than DS Trisomy 21. I was devistated. In the middle of being at work and my friends consoling me about this result after I had told my husband, he called back again and said that his mother was having a heartattack! OMG I fell to pieces. As if just finding out my baby may have some serious health complications wasn't bad enough!
Anyways, the genetic counselor recommended that we have a CVS(chorionic villi sampling). Similar to amnio except this test is extracting placental tissue and not the amniotic fluid. The CVS is 99% accurate whether your child truely has DS or Trisomy 13/18. We went ahead with the testing and also had extensive US to look at the Nunchal fold etc. Our results were back in 48 hours and they were negative!!!! So again another false positive test here. What a relief! And by the way my mother in law did survive her triple bypass surgery and is still recovering. SCARY times.
This exactly. My SIL's result was 1/5- their baby was fine. It is most likely that the test being done at wrong time caused an issue, but again, this is just statistics. I hope everything turns out just fine, and that you are able to feel less stressed upon reading these replies.
OMG mskinner30!! That is a lot to deal with. I am so happy everything turned out just fine.
When they call on monday to schedule my appointment with the specialist, I am going to ask again for the level II ultrasound. I really don't want to have to do an amnio, so I am hoping a second blood test and u/s will suffice and will come back clear.
Now, I will try to put all of this aside while I throw a friend a wedding shower tonight and attend 2 other wedding showers this weekend. Sheesh.
I'm 29 and DH is 37 this is our first as well.
I declined any genetic testing because I didn't want to have months of worrying about what a certain test said. I read on another board something about Drs telling a girl her LO would have downs (not a chance but WOULD HAVE it) and turned out her LO was a perfectly healthy child.
So while Drs are really great at what they do, there is still a lot left up to chance in there.
Sure, it said a 1 in 137 chance, but thats also a 136 in 137 chance that EVERYTHING WILL BE FINE! Breathe, relax. Have faith that things will turn out for the best. *hugz*
Just for reference - I did do the full screening NT and everything and my OB's policy is that they won't call you unless you are 1:40 in your chances of having a DS baby. Also, they were very clear to say that it also means there is a 1:39 chance you don't have a DS baby...
Ummmmm...keep in mind that this is an ODDS tool only...not a diagnostic tool. I bet that not one of your "three friends" were told by their dr "Your baby has XXXX issue without a doubt"...because that is a true false positive test. If so, they should have sued their doctor and bought their own island with the proceeds. Something tells me that your three friends don't own an island. So please don't spew false info, K? Thanks.
Rather, I'm sure that your friends were told something along the line of "you have a 1:150 chance of XXXX issue". Guess what...this means that there is a 149:150 chance that NOTHING IS WRONG.
OP: you have less than 1% chance of something being wrong. Hold tight to that number until told otherwise.

Wow, that is amazing! I take it that her amino/CVS results were mixed up with someone else's? Because that is THE ONLY way that she would be told "your baby has DS". I hope she sued and that dr is no longer in practice. But something tells me that is not exactly how it went down in real life.

With a risk of DS, it sounds like you had low AFP. My baby came back with high AFP when I took the test too early. The first thing we did was retest at 16w. My results again showed high AFP and thus a 1:160 chance of an NTD or Trisomy 18. After talking with a genetic counselor, who was ready to do an amnio that day, we decided to wait until after our level-2 US to make any decisions. Our thought was that there is no risk with an u/s but amnio has a risk of loss. Nationally it is 1:200. The dr who would do ours is 1:400. I wavered back and forth on what to do, but DH just could not accept that level of risk. So, I yielded to his opinion knowing that we could always change our minds on the amnio. After a normal level 2 u/s three weeks later, our risk factor changed to 1:1600. LO was born perfectly healthy.
Do know that this is just a risk factor. A risk factor means that 1 person out of x will be impacted. Since our baby was born healthy that doesn't mean I had a false positive, it means that I was one of the 159 out of 160 that go home with a healthy baby who had the exact same test results. So, with women with the exact same results as you, 136 out of 137 will have healthy babies.
I remember how brutal the period of uncertainty was for me, so I don't want to diminish your emotions, but do know that this has a much better chance of being OK than not. Know that most babies with abnormal AFP results will be perfectly fine. The person who mentored me through our scare had low AFP and a risk factor of 1:75. Her child also was perfectly healthy.
P.S. There seems to be some evidence that in healthy pregnancies, outlying AFP results may just give a clue to the sex of the baby. Low AFP may =girl and high AFP may =boy.

I have not had the same experience but we did have a scare a few weeks ago thinking that the baby might have spina bifida. Everything thing turned out fine but I know how you are feeling.
Definately go for the second blood test and get and u/s for piece of mind if you can. Our scare came out of the 19 week u/s (her head measurement was showing possible lemon sign, an indicator for spina bifida). I then took an AFP which came back normal but we still went in for the u/s for piece of mind.
Thoughts, prayers, and hugs coming your way. Best of luck for you family.
