Also known as a "triple marker" test, the triple screen test measures the levels of a protein produced by the fetus as well as two pregnancy-produced hormones in the mother's blood.
Triple Screen
What It Is:
The triple screen is so named because it is a trio of maternal blood tests that are performed to identify problems in the fetus, especially Down syndrome.
Triple screen: A blood test given to a woman between weeks 15 and 18 of pregnancy to screen for an increased risk of the baby having a birth defect.
Triple Screen Test
This test is done in the second trimester to measure three things, the alpha fetoprotien, hCG and estriol. Alpha fetoprotien is usually produced by the baby and is present in the mother's blood in low quantities.
triple screen -- see AFP
septate uterus -- a uterus with a band of tissue coming down the middle.
Triple Screen-See multiple marker screening.
Trisomy 21-See Down syndrome.
Triple Screen - A protein produced by a developing fetus that is present in amniotic fluid and in the mother's blood. The early blood test is called the triple screen and should be performed between the 15th and 18th week of pregnancy.
triple screen ~ blood test that indicates if there's an increased risk of a birth defect, or a condition like Down Syndrome, in the fetus. This test can also show twins.
The triple screen test has a high rate of false-positive results, which increases with the mother's age. This means you may have a lot of unnecessary anxiety if you have the test, if it comes back with positive results even though your baby is normal.
The triple screening measures the amounts of three substances in a pregnant woman's blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol (uE3). When a test for the hormone inhibin A is added, it's called a quad screening.
The triple screen might be given as a probability such as: 'based on maternal age your risk of Down's is 1/390 --- when the levels of AFP, HCG and uE3 are also taken into account, your risk is 1/14000.
Maternal serum screening, or multiple marker screens (MMS) - These tests - AFP, triple screen, ...
Maternal serum screening - These tests - AFP, triple screen, or quad screen - measure levels of hormones in your blood to try to predict your fetus' risk of various genetic problems and birth defects.
Should I have the maternal serum triple test (triple screen)?
Should I have an early fetal ultrasound?
Should I have an amniocentesis?
Should I have chorionic villus sampling?
Should I bank my baby's umbilical cord blood?
A similar test is the triple screen. These tests are not really "positive" or "negative" but rather give you a risk profile for neural tube disorders, Down's Syndrome, etc.
The more I read about the triple screen and other prenatal tests, the angrier I get! My husband and I went through those ridiculous tests, which came come back saying we could have a Down's Syndrome baby.
Two common prenatal tests are the quad screen or “triple screen,' offered to women between weeks 15 and 20 of pregnancy, well into the second trimester.
Discuss with your doctor or midwife the pros and cons of taking the triple screen, a blood test given in the next few weeks that measures your baby's risk for birth defects such as Down syndrome and spina bifida.
The triple screen checks alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and a type of estrogen (unconjugated estriol, or uE3). The quad screen checks these substances and the level of the hormone inhibin A.
During the first trimester, pregnant women can have a triple screen blood test for spina bifida, Down syndrome, and other congenital diseases in the baby. Most women carrying a baby with spina bifida will have higher-than-normal levels of a protein...

The maternal alpha-fetoprotein screening for spina bifida and triple screen for Down syndrome risk are examples. After birth, screening of newborn babies is required in almost all states.
An accurate date of conception is important, because it is used in calculating the results of various prenatal tests (for example, in the triple screen test). A decision may be made to induce labour if a baby is perceived to be overdue.
