Various tests and tests are performed in different periods from the beginning of pregnancy to the end. Double screening testing, triple testing and quad testing are among the topics that pregnant women often hear, but don’t know enough about them.
The triple screening test, triple testing, Trisomy 21 test and triple-screening test, called triple screening, are the 16th of pregnant women’s pregnancies. and the 18th century. It’s a scan he does during his weeks.
This screening test will be screened in the 15th century. and 22. can also be done between weeks, but it will ensure that more accurate results are obtained, which is applied at the most appropriate time intervals.
What to Know About the Triple Scan Test
Thanks to the developing knowledge of medicine and rapidly advancing technology, possible problems can now be detected in advance even when the baby is in the womb.
One of the biggest fears of women who are pregnant especially at late age is that their baby is born with one of the abnormalities such as Down syndrome, Edward syndrome or nervous pathdisease.
Getting pregnant at a late age is not the only factor for the risk of anomaly in the baby.
However, people with chromosomal abnormalities in their family, those who use addictive substances, some acne treatments, such as taking drugs, the risk of anomaly increases. There are also babies born with chromosomal anomaly, although they are rare, although there are no problems or symptoms.
That’s exactly why the triple screening test is; all pregnant mothers are expected to be given the 16th to 18th birthday of the pregnancy period. is a recommended blood test between weeks. In the blood sample taken from the mother’s candidate, 3 different hormone measurements are performed. This hormone measurement; The age of the mother or her mother is processed by entering into a special computer program with variables such as her weight, smoking or not.
As a result, it is found that women with the characteristics of the expectant mother give birth to a baby with chromosomal abnormalities at a rate of proportion. The result is a guiding quality for the expectant mother who performed the test in the coming weeks.
The most important thing to know about the triple scan test is that they only show the odds, like other screening tests. In short, it is not a diagnostic test. As a result of screening tests, it is not clear whether the baby has chromosomal anomaly.
How to Take a Triple Scan Test?
A triple screening test is performed by taking blood from pregnant women. As a result of the blood received from the mother-in-field person, 3 substances are examined. They are in order;
Alpha-feto protein (AFP)
It doesn’t matter if you’re hungry or full during a triple scan test. After the release of blood tests, the doctor examines the baby with the help of ultrasound and the results are evaluated after a while.
What Risks Are Determined in the Triple Screening Test?
Trisomy 21 (Down Syndrome): Down syndrome, formerly called mongolism, is the 21st century in human chromosome sequence. is a structural disorder caused by chromosome, which is three pieces when it is actually supposed to be two pieces.
This causes a special type of intelligence retardation and a differentiation in physical characteristics. People with Down syndrome; they are generally flattened, short-fingered, small nose and matte type.
Down syndrome test is 1/250 limit at its normal values. If hormone values are higher than this limit, it’s clear that there’s a risk. In addition, cases where the hormone HCG is higher than 1.5 are considered risky.
Trisomy 18 (Edwards Syndrome):
Edwardian syndrome; it is a serious problem that causes problems such as organ failure, retardation of intelligence and developmental retardation.
Babies with these chromosomal anomaly usually die in the womb without waiting for birth. However, there are babies who died shortly after birth.
Although life expectancy can be extended with rare maintenance and interventions, unfortunately, it ends in the same way.
The blood values limit for Edward’s syndrome are 1/100. If the values are higher than this rate, the risk of Edward syndrome may be mentioned.
Neural Type Defects (NTD):
Neural Type Defects; It is the name given to problems that occur during the closure of the neural tube, which forms the brain and spinal cord, which is referred to especially with folic acid deficiency. Among them are; Serious problems such as anencephaly, spina bifida and iniencephaly are involved.
In this test evaluation, the AFP values in the blood are compared to the week of pregnancy. If the AFP value is higher than 2.0, it is considered to be at risk of neural tube problems. The higher the rate, the higher the risk.
After evaluating the results of the doctor, he may recommend conducting tests that present definitive diagnosis, such as amniosynthesis, depending on the risk situation. This is not a method applied to every mother candidate. In cases where the risk is high, it is requested for further examination.
