Dual Test Screening

What is Dual Test Screening?

Dual test screening is also known as the nuchal thickness test in the health field and is performed quite a lot.  This test is performed to detect diseases called Down syndrome and Trisomy18. It is a rather important procedure for pregnant women. It is recommended by our specialist physicians to have the baby done in order to have information about the health status.

As Safir Lab, we provide the detection of these diseases in the early stages of pregnancy within the scope of the test we perform. In all pregnancies, there is a possibility that a physically or mentally disabled baby will be born. Our health center binary scan test can be determined whether or not that is specified by the disease.

Studies say that about one in twenty pregnancies may have birth defects, the severity of which can range from anatomical abnormalities to mental retardation. Some couples have a much greater risk of having a child with birth defects than others, depending on certain factors. This risk for an inherited condition can be detected with the help of genetic screening.

The scan is usually done after eight weeks of pregnancy, age-related birth defects or genetic disorders and toxic environmental exposure at high risk for familial or due to a series of diagnostic tests to help identify different couples to take advantage of. Prenatal screening tests are usually non-invasive and can be done in a few minutes.

A double marker test is a type of prenatal blood test that is performed during the first trimester of pregnancy to check for any abnormalities that may be present in the baby’s chromosomal development. Such abnormalities in the chromosomes can lead to serious health conditions and disorders that can affect the baby’s growth inside the fetus and even later in life. The double marker test can help to determine in advance the possibilities of certain disorders, such as Down syndrome or Edward syndrome. This test is often recommended because it is a very reliable test that helps to detect abnormalities quite accurately.

The dual screening test is performed for pregnant women and it happens in order to identify any chromosomal malformations in the fetus. This test also plays a vital role in detecting all kinds of neurological conditions in the fetus, such as Down syndrome or Edward’s Syndrome. Chromosomal abnormalities in the fetus can cause serious developmental disorders and lead to various health problems in the child after childbirth, but such abnormalities are extremely rare.

This test is especially performed for people who have previously had birth defects in their family. it is also common to be done to pregnant women over the age of 35. In addition, this may also need to be done for women with the insulin-dependent condition type 1 diabetes.

Dual Test How is the Down Syndrome Test Performed?

Performing a dual test is performed by ultrasound. Nuchal thickness examination is one of the ones performed in this context. Measurement is performed for the liquid located on the neck of babies in a millimeter way. In addition, the presence of the nasal bone is also checked. Because in 50% of babies with Down syndrome, there is a situation in which the nasal bone develops very little or does not develop at all. At the same time, ductus venosus examination is also performed with color doppler. As Safir Lab, we carry out the dual test screening process in this way and detect problems such as down syndrome and trisomy 18 in your babies.

The dual screening test is performed with an ultra sound test and a blood sample. The dual test looks for two markers, namely Free Beta hCG (human chorionic gonadotropin) and PAPP – A (Pregnancy-associated plasma protein A).  Free Beta hCG is a glycoprotein hormone produced by the placenta during pregnancy. A high level is indicative of a higher risk of Trisomy 18 and Down syndrome. PAPP – A is a vital plasma protein. A low plasma protein level is an indicator of the risk of down syndrome. The test readings are expressed as screen positive, high risk and screen negative.

The various uses of the dual screening test are as we have stated;

• It helps to assess whether the unborn baby is at risk for any mental disorders.
• is primarily used for the detection of Down syndrome.
• The Double Screening Test also helps to detect Trisomy 18, which results in mental retardation and severe birth defects.
• Also Trisomy 21, which causes mental disorders, heart disorders and other health problems that affect vital organs.It also helps in the detection of T.

The double marker test is performed by an ultrasound, and the test results are generally divided into two categories: screen positive and screen negative. The test results are also linked to the age of both the mother and the fetus. These are important in determining the result. It is observed that the blood sample checks the levels of the hormone free beta HCG and pregnancy-related plasma protein A (PAPP-A). This glycoprotein hormone is developed by the placenta during pregnancy. High levels of free beta hCG indicate a higher risk of Down syndrome, and low protein levels also pose a risk of Down syndrome.

The result of the double marker test is presented in the form of proportions. If the ratio is between 1:10 and 1:250, then the so-called “screen positive” result, which is located in the high-risk zone, is Deciphered. a ratio of 1:1000 or above is called a “screen negative” result, which indicates a low risk. These ratios are pointers for understanding the likelihood that a child will suffer from any disorder. In the event that the result of the double marker test is positive, the doctor may recommend further diagnostic procedures such as amniocentesis or chorionic villus sampling to find out the problem.

How Are the Results of the Dual Test Scan Evaluated?

After the double trimester screening, the results are presented to you. The results obtained are evaluated by our specialist doctors and as a result, information is transferred to you. We will provide you with information about whether you will have a baby with Down syndrome by providing a rate in this way. It is also possible to have positive and negative results at the same time. For people who will have a dual test screening, it should be noted that within the scope of this test, the risk of your baby carrying trisomy 18 and Down syndrome is evaluated.

If there is a risk, it will be shared with you. It is one of the tests that are definitely recommended for pregnant women in our health center in order to make an early diagnosis and inform about the possibility.

Frequently Asked Questions About the Dual Screening Test

People who are going to have a double test may wonder many things about both themselves and their babies before this test. For those who are curious about the gender of the baby, it can be said that the gender can also be learned within the scope of taking the appropriate image during this test. Women may also want to know where to take the test.

Mostly this procedure is performed by ultrasound method from the abdomen. If necessary, vaginal ultrasound can be applied for a 10% cut. Dual test screening is performed in this way in our health center.

It is very curious what trisomy 18 is. An extra 18. it is also known as Edwards Syndrome, which occurs as a result of the development of the chromosome. For this reason, the normal development order of the baby is disrupted before it is even born. The effects caused by trisomy 18 are very complex compared to Down syndrome. Its effects are so severe that it can cause stillbirth of the child (death at the time of birth).

One may also wonder what Down syndrome is. 21. it is a genetic disorder in which extra genetic material is transferred from the chromosome to the fetus. This transfer affects the development of the fetus, leading to abnormal development, both physically and mentally. The affected baby will have a small head and short neck, slanted eyes looking upwards, a tongue large from the mouth, a flat face, wide hands with short fingers and a lack of November muscle tone.

People who are going to have an MRI may be concerned about whether there is any risk. There are no risks associated with the test. However, since this test requires a needle prick to take a blood sample, in very rare cases, a patient may experience increased bleeding, hematoma formation (collection of blood under the skin), bruising, or infection at the site of the needle prick.

One of the most frequently asked questions is what is measured by the test. With the test to be performed, we measure the b-hCG and PAPP-A found in the blood. b-hCG is produced through cells in the placenta. And this happens during pregnancy. In early pregnancy, b-hCG levels increase. The role of b-hCG in early pregnancy is to maintain the function of the corpus luteum (the hormone-secreting structure that develops in the ovary). During the first three weeks, the production of b-hCG increases and increases by 10. it reaches the highest levels per week (from the last menstrual cycle). After that, within a few weeks after childbirth, b-hCG levels begin to decrease to a negligible level.

The placenta provides PAPP-A secretion. Their levels, on the other hand, increase over time during the pregnancy process. Due to some tissues, PAPP-A levels are expressed in low amounts. PAPP-A rates also increase due to plaques located in the coronary artery but are not stable.

It is possible to perform a dual marker test along with a Nuchal Translucency test to confirm the diagnosis of any genetic abnormality.

Nuchal Translucency (NT) is a measurement of the fluid under the skin along the back of the baby’s neck. NT is measured by ultrasound.

The main reasons for conducting the test can be shown as follows:

• In case of Down syndrome, it should be diagnosed
• To detect trisomy 18
• Ladies with a family history of any of these syndromes

Reminders of the Importance For Dual Screening Test Review

It will be better for you to be in comfortable clothes before the test. At the same time, don’t forget to ask our doctors about the things you are curious about. If you have a special situation, be sure to let us know about it.

The Dual Marker test helps you to go to other diagnostic tests if it turns out positive. If the test is performed earlier in pregnancy and comes out positive, early decisions can be made. All women, regardless of age, should be screened for a double marker test for any prenatal abnormalities during pregnancy. The ideal duration of this test is between Dec 10-13 weeks of pregnancy. However, it can be done Decently between 9-13 weeks of pregnancy.

Factors that are taken into account by doctors before prescribing a double marker test are; if the woman has reached the age of 35, if there is a family history of congenital disability, and if there is a family history of diabetes, these should be addressed. The dual test is essentially a blood test that does not require any preparation. Any medical condition or allergy should be reported to the doctor before the test is performed. You may be asked to discontinue the use of certain medications before taking a blood test.

The double test is also known as the Double Marker Test. This test measures the levels of b-hCG and Pregnancy-Related Plasma Protein (PAPP-A) in the blood. It is usually recommended to women over the age of 35, as they are at risk of giving birth to a baby with Down syndrome. Apart from that, it is also recommended to young ladies. This test helps to screen the fetus for any abnormalities before delivery. 9-13 of pregnancy. it can be done between weeks, but the ideal time for a combined risk assessment is 10-13 weeks Dec.
