Trisomy 18 1 350 20

Hello, I think it is needed, fetal amniotic fluid test is the most reliable and not very harmful to the body.

Trisomy 18: 3141

Hello Dear is also known as Edwards syndrome. The teromorphic band of trisomy 18 syndrome mainly includes abnormalities of the mesoderm and its derivatives (eg, bones, genitourinary system, and heart). In addition, ectoderm (e.g., folds, crests, hair, etc.) and endoderm (e.g., Merkel's diverticulum, lungs, and kidneys) close to the mesoderm are also abnormal.

The literature reports that embryos develop normally before 5 weeks and begin to develop abnormalities at 6 to 8 weeks of gestation. Trisomy 18 (Edwards syndrome) is the second most common chromosomal tribody sign after congenital stupidity. In 1960, Edwards et al. first reported a case of multiple malformations in a child with multiple malformations, who had an extra chromosome after chromosomal examination, which was considered to be chromosome 17, and many scholars successively reported similar observations, confirming that these clinical syndromes were related to the abnormality of chromosome 18 in Xingyan.

Summary. Trisomy 18 (Edwards syndrome) is the second most common chromosomal tribody sign after congenital stupidity. In 1960, Edwards et al. first reported a case of multiple malformations in a child with multiple malformations, who had an extra chromosome after chromosomal examination, which was thought to be chromosome 17, and many scholars have reported similar observations one after another, confirming that these clinical syndromes are related to chromosome 18 abnormalities, and hundreds of cases have been reported so far.

The main clinical manifestations are multiple malformations, more than death in the first few weeks of life.

Trisomy 18: 1605

Hello, I have seen your question and am sorting out the answer, please wait a while Trisomy 18 (Edwards syndrome) is the second most common trisomal sign after congenital stupidity. In 1960, Edwards et al. first reported a case of multiple malformations in a child with multiple malformations, who had an extra chromosome after chromosomal examination, which was thought to be chromosome 17, and many scholars have reported similar observations one after another, confirming that these clinical syndromes are related to chromosome 18 abnormalities, and hundreds of cases have been reported so far. The main clinical manifestations are multiple malformations, more than death in the first few weeks of life.

Is my ratio normal?

The cut-off value for trisomy 18 is 1 350, which is higher or equal to the high risk. Of course, the result on the report is a matter of probability, which means that you have a high risk of this congenital abnormality, and does not represent a diagnosis, so it is recommended that you go to the hospital for a check-up.

Summary. Trisomy 18 refers to fetal trisomy 18, as the name suggests, there is one more chromosome 18, which is three, and normal people, including fetuses, are diploid. Trisomy 18 is also a chromosomal abnormality that generally excludes itself during the fetal period and dies in utero.

Even if they survive, they don't live long after giving birth, but a very small number of chimeras can survive, and even if they survive, they are multiple malformations.

Trisomy 18: 6208

Hello!

Trisomy 18 refers to fetal trisomy 18, as the name suggests, there is one more chromosome 18 in the grip, which is three, and normal people, including the fetus, are diploid and have two. Trisomy 18 is also a chromosomal abnormality that generally excludes itself during the fetal period and dies in utero. Even if he survived and gave birth, he Pi Zhao would not live for too long, but a very small number of chimeras could survive Zenkai, and even if they survived, they were multiple deformities.

Dear, you're fine.

The period between 1:350 and 1:1000 is a critical risk and needs to be further improved.

Amniocentesis can be definitively diagnosed, but it is an invasive procedure that carries some risks. You can also do non-invasive DNA testing first, which is to draw the maternal blood file for testing, which is relatively safe, and the accuracy rate of the round quasi-start beat can reach more than 99%.

You help me look at this checklist, okay, dear.

The risk rate for Down syndrome is usually 1:270 as normal. If the test result value is greater than this value, the risk is higher, and below this value, the risk should be low.

Dear, your Down syndrome ratio is relatively high, 1:186 is the cut-off value of 1:270.

Generally 1:270 is low risk.

You're at high risk.

You should do further genetic counseling, and then further negotiate with the hospital whether to perform amniocentesis for further diagnosis.

Trisomy 18 followed by neural tube defects.

Trisomy 18 is a low-risk 1:6208 cut-off value.

Neural tube defects are also within the reference value range, and they are fine.

The first problem is big.

Thank you. You're welcome!

Trisomy 21: 4736

Good evening kiss in front of the screen, glad for your question. 21 Three-body comprehensive filial piety book combination, also known as congenital foolishness. It is an autosomal abnormality.

The main reason is that the 21st pair of chromosomes has three chromosomes, not a normal pair. It can cause the fetus to be born after birth, including learning disabilities, intellectual disabilities. During pregnancy, a Down screening assignment is required to understand the risk of developing trisomy 21.

The normal range for trisomy 21 is less than 1:270. If a value is found to be greater than 1:

270, suggesting that the fetus has a high probability of developing Down's children, and it is not that Qiao Xianhong has 100% Down's children.

Summary. Trisomy 18. The normal value is 1:

350。If it is higher than this value, it is considered a high risk. In other words, the probability of trisomy 18 is very high.

But it's not necessarily trisomy 18. If you are not sure, you can do a non-invasive DNA test. Or do an amniocentesis.

If both tests are normal. That would rule out chromosomal malformations in the fetus.

The risk value of trisomy 18 is 1: 31153

Trisomy 18. The normal value for is 1:350.

If it is higher than this value, it is considered a high risk. In other words, the probability of trisomy 18 is very high. But it's not necessarily trisomy 18.

If you are not sure, you can do a non-invasive DNA test. Or do an amniocentesis. If both tests are normal.

That would rule out chromosomal malformations in the fetus.

Some pregnant women have high ketones or HCG during pregnancy. It is also possible to cause a high risk of Tang screening. The calculation method of Tang Sieve is related to these two values. Therefore, further testing is recommended.

It doesn't have to be that the fetus has a malformation, and I hope it will help you.

Summary. Hello dear, the data I found for you shows that the risk rate of trisomy 18 is greater than 1:

1000 is normal. Trisomy 10 is a chromosomal disorder, and if the ratio is less than 1:250, it is considered high-risk, 1:

250 1:1000 is a critical risk, and greater than 1:1000 is generally a normal situation.

If it is a high risk or borderline risk, it means that the relative probability of disease is relatively high, and further non-invasive DNA or amniocentesis is recommended for examination.

Basic risk of trisomy 18: 2341

Hello dear, the information I found for you shows that the risk rate of trisomy 18 is greater than 1:1000, which is normal.

Trisomy 15 is a chromosomal disorder, and if the ratio is less than 1:250, it is considered high risk, and 1:250 1:

1000 belongs to the risk of the base of the cherry tree, and greater than 1:1000 is generally a normal situation. If it is a high risk or a critical risk of spinal rush, the relative probability of disease is relatively high, and it is recommended to do further non-invasive DNA or amniocentesis for examination.

Let me go to this, did you see the ** I sent you?

Did you see the ** I sent you?

This can not be done without further examination.

This is a high-risk disease.

Please also go to the hospital for further examination.
