What should I do if the screening result of Tang is high risk?

What about the high risk of Tang sieve results? Most pregnant mothers are nervous and worried when they hear the word Tang sieve. They are afraid that the result of Tang sieve is high-risk, which means that the probability of the fetus in the abdomen is relatively high. So what about the high risk of Tang sieve results? Go and have a look.

What should I do if the screening result of Tang is high risk? Tang Screening 1 How to deal with high risks?

The early detection rate of Down's screening is 85%-90%, and the probability of false high risk in the middle stage is high.

The word "high risk" appears, suggesting that the probability of fetal illness is high, but it does not mean that there must be something wrong with the fetus, and pregnant mothers need not panic too much.

Next, it is necessary to further confirm whether the fetus is really Down syndrome. The diagnosis of Down syndrome is generally confirmed by non-invasive genetic testing, amniocentesis or villus examination.

The value of high risk in early Tang dynasty is obtained by the cumulative multiplication of multiple individual risks, such as age, MoM value of PAPP-A, mom value of β-HCG, NT value and so on.

If the nt value is less than 3 mm, but the early Tang Dynasty suggests high risk, pregnant mothers can basically rest assured, because NT has more reference significance. If you are really uneasy, you can do non-invasive genetic testing.

If the NT value is greater than 3 mm, in addition to chromosome problems, we should also pay attention to other diseases indicated by NT thickening, such as congenital heart disease, and decide whether amniocentesis is needed under the guidance of doctors to diagnose all possible chromosome problems.

If NT is 3. 5, 4 or even higher, after the non-invasive gene detection is normal, amniocentesis can be continued to make a complete diagnosis of chromosomes.

What should I do if Down's review risk is high in the middle term?

If you don't do NT and early Down's screening, only do mid-term Down's screening, and get high-risk results, you can accept non-invasive genetic testing. If the test results are normal, you can rest assured to enjoy your life during pregnancy.

If the test results are abnormal, you should make an appointment for amniocentesis immediately. Because NT was not done, the results of screening in mid-Tang Dynasty were not as accurate as those in early Tang Dynasty, which only indicated the problems of two basic chromosomes, 2 1 trisomy and 18 trisomy, and could not indicate the problems of congenital heart disease or malformation.

In short, the high risk of Tang screening does not mean that the baby must have problems. Pregnant mothers can summarize their own situation, such as age, heredity and gestational age. And do further examination according to your own needs to confirm the baby's situation.

What should I do if the screening result of Tang is high risk? Don't panic when screening high risk, just check it step by step according to medical regulations.

Generally, amniocentesis is the first choice for high-risk screening of Down's syndrome. Amniocentesis is used to extract amniotic fluid, culture fetal cells in it, and directly observe the number and structure of chromosomes in fetal cells. As a means of diagnosing fetal chromosomal abnormalities, amniocentesis is mainly used for screening high-risk groups and women over 40 years old.

In fact, it is very rare that high-risk patients with Down's screening are finally diagnosed as abnormal amniocentesis. Most amniocentesis of Down's screening high-risk patients will be normal, so don't worry too much. It is not recommended to use fetal DNA test to diagnose the high risk of Down's screening, because fetal DNA test is also a screening method, not a diagnosis method.

Down's screening is a very important examination during pregnancy. If Down's screening results show high risk, babies with chromosomal abnormalities may be born. This kind of baby is mainly characterized by slow growth, low intelligence and generally poor survival ability after birth.

Once there is a high risk, further prenatal diagnosis is needed. Now prenatal diagnosis, first of all, it is recommended to carry out interventional prenatal diagnosis, that is, to extract the corresponding villi, amniotic fluid, or umbilical cord blood to check the chromosome of the fetus.

There is also a non-invasive genetic test, which is mainly aimed at critical risks. If high-risk pregnant women really don't want to take the risk of intervening in prenatal diagnosis, they can also choose non-invasive genetic testing as appropriate. If there is something wrong with the results of non-invasive genetic testing, it is necessary to further carry out interventional prenatal diagnosis.

Tang Screen suggested that high-risk patients generally need amniocentesis.

High risk is an increased risk of Down syndrome. Increasing only means increasing risks, but it is not necessarily a problem. This kind of situation should generally go to a hospital with prenatal diagnosis qualification.

Because Down's screening is just a screening experiment, the rest is to do a confirmation experiment, and the confirmation experiment can only collect the amniotic fluid cells of the child, and determine whether the child is really a Down's child by checking the chromosome core of cell culture analysis.

Down's screening is also called Down's screening. The risk of Down's syndrome screening is high, which indicates that the fetus is more likely to suffer from Down's syndrome and needs further examination. Non-invasive DNA testing is generally not recommended for the diagnosis of high-risk population in Down's screening, because fetal non-invasive DNA testing is also a screening method rather than a diagnostic method.

Amniocentesis is recommended. Amniocentesis is a diagnostic method, but the risk is high. If the amniocentesis result is abnormal, the pregnancy should be terminated.

What if Down's screening suggests high risk?

1, need to be diagnosed as Down syndrome.

It should be noted that even if the screening result of Down syndrome is "high risk", this situation can only show that the probability of fetal Down syndrome is higher than the international standard value, but this does not mean that the fetus must be Down syndrome.

In this case, further amniocentesis or chorionic villus examination is needed to confirm whether the fetus really belongs to Down syndrome.

2. Post-diagnosis treatment

Generally speaking, there is no effective treatment for Down syndrome at present. In order to ensure that the fetus is not deformed, the best way is to terminate the pregnancy.

3. Adhere to the pregnancy test.

Generally speaking, 60% to 80% of children with Down's syndrome can be screened by Down's screening test. However, the screening test can only help to judge the probability of Down's syndrome in the fetus, but can't confirm whether the fetus has Down's syndrome.

Therefore, if the blood test index of pregnant women is high, it means that pregnant women have a higher probability of Down syndrome, but if the test index is normal, there is no guarantee that the fetus will not suffer from Down syndrome. Therefore, it is suggested that pregnant women must insist on doing various pregnancy tests in order to accurately understand the development of the fetus.

In addition, it should be reminded that the best time for pregnant women to do Down's screening is usually 14 weeks +6 days to 18 weeks +6 days.

In other words, it is best for pregnant women to have Down's screening in 16 weeks 18 weeks. It should be noted that whether down's screening is done in advance or delayed, it may affect the accuracy of the test results.

In addition, if the time period of Down's screening is missed, then pregnant women can't make up for Down's screening. At this time, you can only do an amniocentesis to achieve the purpose of screening. Relatively speaking, this exam will be much more troublesome than Tang's screening.
