Results from the Multiple Marker Screen (MMS, also called Triple Screed) are usually available within several days to a week. Most doctors will call their patients with results only if they are abnormal, since additional testing may be offered. However, if you are anxious about the results, it would be perfectly appropriate for you to call your doctor for the results rather than wait until your next scheduled appointment.

How common is a positive result?
Only about 3 to 5 percent of women will receive a positive (abnormal) result on the multiple marker — and on average, only about 10 percent of those women will actually have a baby with a problem. That adds up to a lot of false positive results.

Statistics from one of the companies that offers a multiple marker test show an even higher rate of false positives: If 1,000 pregnant women take this test, only about 25 of them will show an increased risk for a baby with neural tube defects, and of those, only one or two will actually have a baby with a defect. About 70 of the 1,000 will show an increased risk for a baby with Down syndrome, and of those, only one or two will actually have a baby with Down syndrome. On the other hand, some women whose test results are normal will have a baby with one of these problems.


What does the triple test look for?
The triple test is measuring high and low levels of AFP and abnormal levels of hCG and estriol. The results are combined with the mother's age and ethnicity in order to assess probabilities of potential genetic disorders.

High levels of AFP may suggest that the developing baby has a neural tube defect. The most common neural tube defects are spina bifida and anencephaly.

Low levels of AFP may indicate that the developing baby has Down syndrome (Trisomy 21).

Abnormal levels of hCG and estriol may indicate that the developing baby may have chromosome abnormalities.

Although the primary reason for conducting the triple test is to screen for genetic disorders, the triple test has also been used to identify:

Defects in the ventral wall of the baby
Defects in the digestive system of the baby
Women carrying twins
Pregnancies that are more or less advanced than thought
Risks of premature birth, preeclampsia and miscarriage
What do the triple test results mean?
It is important to remember that the triple test is a screening test and not a diagnostic test. This test only notes that a mother is at risk of carrying a baby with a genetic disorder. Many women who experience an abnormal test discover later that the test proved false.

The results for AFP, estriol and hCG levels are usually phrased as high or low values. For example, the combination of a low AFP, low estriol and a high hCG suggests further screening for Down Syndrome.

It is important to understand the MMS test is JUST A SCREENING TEST. Every woman has a risk of having a baby with abnormalities. Certain abnormalities are associated with the age of the mother. No one has a risk of o. The risk of chromosomal abnormalities is directly proportional to the age of the mother. The MMS test combines the age related risk with blood chemistry to generate a new risk. The ONLY WAY TO COMPLETELY RULE OUT A CHROMOSOMAL ABNORMALITY IS THROUGH GENETIC TESTING, i.e., amniocentesis or chorionic villi sampling (CVS; by obtaining a tiny piece of the placenta).

If your test is positive, you should speak to your doctor about a Level II ultrasound examination, where a extended and more detailed examination is performed. If the Level II is complete and is normal, the risk you now have is better by double. For instance, if your age related risk is 1:500 and the MMS screen adjusts that risk to 1:100 a Level II ultrasound examination with normal results would again adjust your risk to approximately 1:200, still higher than your original, age related risk.

The MMS test is dependant on accurate gestational age dating of the pregnancy. If your dates are off, the MMS will come back with an false positive.

Some women simply have positive tests with each pregnancy for no apparent reason. I am an ultrasound technician and I've seen this scenario many times.

Try to relax. Even if your risk is, say, 1:10, which is extremely high risk, that translates to a 90% chance everything is ok.

Good luck and try to enjoy your pregnancy.

That test is called a triple screen and I did not take it because the false positive rate on the test is extremely high and then you are stressed for 4 months to find out nothing was even wrong with your child so don;t worry to much

if you don't hear anything back from the doctor and you really want to know, call them after a week or so. the tests aren't always accurate. if it does come back positive, they will send you to a specialist to get other tests done. i have heard of false-positive tests before. don't worry, putting yourself through unneeded stress isn't good for the baby.

In my opinion, the test always comes back with some degree of "something" wrong, but with my experience in having three kids, 2 nieces and a host friends with babies, everytime it has been wrong.

I heard back from mine in about 2 weeks, they changed my due date though so they had to rerun the tests. Good Luck, I wouldn't stress it

to check for downs syndrome and spinal bifida.
The test usually indicates the need for more tests, but if it is something to worry about they will let you know in one week, after that it is usually ok

No i dont know the test, but they do many. It kind of sounds like an amniocentesis to check for birth defects and what not. If you dont have your results, call them and ask.
