What is the quad screening?

I got a quad screening at about 18 wks and I am not sure what they are measuring to come up with that. Is it common stuff in your blood that is believed to be an indicator that your child will have downs, or whatever else they tested for? It was all negative but I was just wondering.

That's what it is, they test for downs. They tend to get a lot of false positives, but mine all came back negetive.

Re: What is the quad screening?

The Quad screening helps identify those women at risk for carrying a fetus with Down Syndrome or a neural tube defect.

The test measures four substances in your blood, hence the "Quad".

The test however does not give you a "yes" or "no" answer, it only tells you the likelihood of a problem.

There are alot of false positives with this test, however, if you test negative, you can pretty much relax. I was told that if you test negative, that the chance of the test being wrong is extremely unlikely. The test must be done before 20 weeks of gestation.

Re: What is the quad screening?

Re: What is the quad screening?

Yes. Once I tested negative, I didn't worry anymore. At least that's what my doctor told me, a negative result is correct but a positive can be a false positive.

They always do the screening. Then at around age 35, they recommend an amniocentesis instead of the quad because your risk starts increasing for downs and by age 40 you have a 1 in 100 chance of having a downs baby whereas at 35 your chance is 1 in 350. I was 36 when I had my daughter, but refused the amnio because my quad was negative and I didn't want a needle going in my water bag.

Re: What is the quad screening?

Well you can decline the test... so they don't -always- do it.

If you are a woman that will not terminate a pregnancy no matter what... there really is no need to take the test in my opinion... unless of course you want to know ahead of time to prepare.

And if your test come back showing an increased risk for certain abnormalities, it does not necessarily mean you have an abnormal pregnancy... just means that further investigation is warranted.

Re: What is the quad screening?

You can decline the amnio, but I don't believe you can decline the quad. My doctor didn't give me the option. The quad also checks for abnormalities that can result in the baby not living or dying in utero such as anencepholy. IN this case, the baby wouldn't live outside the uterus or may die in utero, so the doctor would want to know as well as the mother.

Re: What is the quad screening?

I think with almost absolute certainty that since the quad results are done by a state lab, the test is required by the state and the doctors have to screen each woman.

Not in Florida. I could decline the test if I wanted to. And they asked me yet again if I wanted to do the Quad test at my 16week visit. It is optional.
