I don't think the blood test you just had was the triple screen. That one they do in the second trimester. I don't know for sure, but this is what I think, based on my experience:
I'm guessing the blood test they did the day of the nuchal transluceny test was for cystic fibrosis. I also had that done the day of my NT test, and when they called with the results they said it came back negative. Which means you are not a carrier of cystic fibrosis. But like I said this is just a guess... based on your ethnicity they may have tested you for something else. Different ethnic groups are at higher risks for other things. I am caucasian.
The blood test you go back for in two weeks may be the triple screen blood test. Mine is schedule for 24 Sept.
During my dr visit they explained to me that the NT test alone has about a 80% accuracy of detecting DS and Trisomy 18. Combined with the results of the triple screen, it is supposed to be 90% effective. They said after both tests they come up with an over all risk factor. My dr did call me with the results of the NT test, and they did give me a risk factor. I was surprised by this because of what they said at the appointment. I'm guessing after my triple screen they come up with a new number based on the additional information.
Congrats on the results of your NT screening.. and good luck in two weeks!!
Thanks so much. I am still a little confused because I am doing a "quad" which is 2 blood tests weeks apart then compared. One of those tests is the triple screen. I assumed the one I just had was for Downs and Tris, but now I don't know. I wish I had a Dr in the family!
Do you have the "what to expect when you are expecting" book.. If so, go to page 48. It talks about the first-trimester screening and says that it is a combo of u/s and blood tests. The blood test is for high levels of PAAP-A and HCG. The book also talks about the triple screen on pag 48. I'm not sure what the quad is.
OMG! Your a life saver...Thanks for the tip!
I flet the same way after my nuchal.....everyone was posting numbers and the chance of downs and all my Dr said to me was everythign looked OK....errrr. My friends was told the same thing (we do go to same DR) just that everythign was OK. I didnt let it bother tooo much but kinda wish I had thenumbers to compare but hey "everything looks good" LOL
If you do the first trimester integrated test they send your blood off to some company and run the NT u/s. The results of the blood(hcg and papp-a) plus the NT ultrasound will give you a risk factor like 1:3000. The nuchal HAS to be done before 13w6d.
The quad test is different - it is only blood drawn at 16-18weeks. It measures 4 different things inclucing the papp-a and hcg from the first trimester test along with afp and estriol (i think).
I did the first trimester screen and got numerical results for downs and trisomy risk. Then at 16 weeks I did 1/4 of the quad screen (the afp portion). Since I already had a risk factor for downs and trisomies the entire test was not necessary. The afp portion gives a risk of spina bifida that is not tested in the first trimester screen. For that result my ob only said it was "normal" and did not give any numbers for the afp. If you want the numbers though ask for them. They are yours and you have paid for them.
I guess when I go in on the 25th, I'll ask for the %'s if they have them because at this point, I don't know what my other 2 blood tests and NT were for and why they tell me I came back negitive. I have a 3rd blood test scheduled for that day too. Maybe they are secretly vampires and the whole thing is a sham.....
I read the What to expect part and it made sense, but I was told by my Dr the "Quad" was done over a few weeks and involved 2 blood tests from different samples. I guess need to be a little more prodding in my questions to be sure I get the info I need.
