Prenatal screening is an important part of pregnancy, and the accuracy of these tests is paramount in ensuring families are getting the best possible care. So how can we ensure accuracy when it comes to detecting Down syndrome pregnancies? In this article, we take a look at Triple Marker Test and its ability to offer more reliable detection rates than other methods – so keep reading to find out more!
What is Triple Marker Testing?
Triple marker testing is a blood test that measures the levels of three specific substances in the mother’s blood: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol. This test is usually performed between weeks 15 and 20 of pregnancy, and it can help to more accurately detect Down syndrome pregnancies.
AFP is a protein produced by the developing baby. hCG is a hormone produced by the placenta. Estriol is a hormone produced by the woman’s body during pregnancy.
The triple marker test results are reported as multiples of the median (MoM). The MoM is a value that compares the level of each substance in the mother’s blood to what is typically seen in other pregnant women. A MoM of 1.0 means that the level of the substance in the mother’s blood is average.
A high AFP level, combined with low hCG and estriol levels, may be indicative of an increased risk for Down syndrome. However, false positive results are possible, so this test should used in conjunction with other tests, such as nuchal translucency testing or amniocentesis, to make a final diagnosis.
How Does This Test Work?
This test is also called a multiple marker screening test, and it is usually done between the 15th and 20th weeks of pregnancy. It involves taking a blood sample from the pregnant woman and testing it for three specific markers: alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and estriol (uE3).
The levels of these markers are then compared to what is considered normal for each week of pregnancy. If the levels of any of these markers are higher or lower than normal, it could be an indication that the fetus has Down syndrome.
How Much Does It Cost?
The cost of triple marker testing varies depending on the clinic or hospital where you receive the test, but is generally between $200 and $300. Some insurance companies will cover the cost of the test, but others may not. It is important to check with your insurance company beforehand to see if they will cover the cost.
The average cost of a triple marker test is between $200 and $300.
There is no set cost for triple marker testing as it is typically covered by insurance. However, some insurance companies may not cover the full cost of the test or may require a higher deductible. In these cases, the out-of-pocket cost for the test can range from $100 to $400.
The Value of Triple Marker Testing
Triple marker testing is a blood test that measures the levels of three specific hormones in the pregnant woman’s blood. These hormones are estriol, human chorionic gonadotropin (hCG), and alpha-fetoprotein (AFP).
The estriol level is usually lower in women carrying a baby with Down syndrome. The hCG level is usually higher in women carrying a baby with Down syndrome. The AFP level is usually lower in women carrying a baby with Down syndrome.
A woman’s age, weight, and ethnicity may also affect her test results.
Triple marker testing can help to give a more accurate picture of whether or not the fetus has Down syndrome.
Down syndrome is a chromosomal condition that results in intellectual disability and physical abnormalities. It occurs when there is an extra copy of chromosome 21 present in the cells of the body. This extra chromosome can inherited from either parent, or it may occur as a spontaneous mutation during cell division.
There are several different types of triple marker tests available, but they all work by measuring the same three markers.

Drawbacks of this testing method
There are a few potential drawbacks to this testing method. First, it is slightly more expensive than other screening options, so not all insurance companies will cover it. Additionally, because it involves taking three different blood samples, it can be slightly more invasive than other options.
There are a few potential drawbacks to this testing method. First, it is important to note that this test is not foolproof. While it can be quite accurate, there is always a chance for error. Secondly, this test is somewhat invasive. In order to obtain the necessary samples, a needle will need to inserted into the mother’s abdomen. This can cause some discomfort and/or cramping. Lastly, this test is relatively expensive, costing anywhere from $800-$2000.
There are a few potential drawbacks to this testing method. First, it is slightly more invasive than traditional screening methods, as it requires a blood draw from the mother. Second, it is a bit more expensive than traditional screening, though it is still generally covered by insurance.
