Do IVF babies need screening test?

1. Definition and purpose of Tang Sieve inspection

Tang screening test is a prenatal screening method widely used in pregnant women, mainly used to screen trisomy 21 syndrome. It is used to detect the Tang screen indicators in pregnant women, such as serum free β Human chorionic gonadotropin (F β- HCG) and serum cysteine (AFP) during pregnancy, combined with the age, gestational week and other information of pregnant women, to assess whether there is a risk of chromosomal abnormalities in the fetus.

The purpose of Tang screening is to quickly and safely identify high-risk fetuses, provide basis for further genetic diagnosis and testing for high-risk pregnant women, help couples make decisions, and do a good job in relevant prenatal and early childhood interventions.

2. Risk of chromosomal abnormalities in IVF fetuses

IVF is a method of cultivating embryos in the laboratory through artificial fertilization or in vitro fertilization technology, and then transferring healthy embryos to the mother for pregnancy. The risk of chromosomal abnormalities of IVF is slightly higher than that of ordinary naturally conceived infants, which is mainly caused by genetic variations and chromosomal abnormalities that may occur during the cultivation of embryos in the laboratory.

Therefore, for test tube babies, Tang screening can detect high-risk fetuses as soon as possible, providing more comprehensive information and decision-making basis for couples.

For example, if Tang screen results show that the fetus has a high risk of chromosomal abnormalities, couples can choose to further carry out more accurate genetic diagnosis methods such as non-invasive prenatal gene testing (NIPT) or amniocentesis to determine whether the fetus has chromosomal abnormalities related diseases.

3. Test tube baby screening process

The process of screening test for IVF is similar to that of normal pregnant women. Tang screening is usually performed between 11-14 weeks of pregnancy.

Tang screen inspection mainly includes the following steps:

1. Consultation and risk assessment: pregnant women can go to professional medical institutions, such as the obstetrics department of XX Hospital, to receive relevant consultation and risk assessment from Tang Sieve. The doctor will assess the risks according to the age, gestational week, personal signs and other information of pregnant women.
2. Blood sampling: pregnant women need to take a blood sample, which is usually taken by intravenous injection near the elbow, collecting 2-3 ml of venous blood samples, and sending the blood samples to the inspection agency for Tang screening index test.
3. Analysis of test results: The inspection agency will calculate the risk of fetal chromosomal abnormalities according to the test results of blood samples, combined with the age, gestational week and other information of pregnant women.
4. Result notification and further treatment: doctors will interpret the risk of fetal chromosome abnormalities to couples in detail according to the test results, and give corresponding suggestions, such as more accurate genetic diagnosis or active prenatal intervention.

4. Significance of screening test in combination with IVF

For test tube babies, the screening test has its unique significance. First of all, the risk of chromosomal abnormalities in test tube babies is relatively increased. Tang screening can help couples to obtain information about the risk of fetal chromosomal abnormalities in time and help them make reasonable decisions.

Secondly, the birth of IVF requires huge mental and economic investment, and couples pay more attention to the health of the fetus. Tang screening can provide a preliminary risk assessment of fetal chromosomal abnormalities, provide more information for couples, and reduce their anxiety and stress.

To sum up, it is necessary for IVF to carry out Tang screening test, which can help couples understand the risk of fetal chromosome abnormalities in time, provide an important basis for making decisions, and ensure the healthy growth of IVF.

Summary: Test tube babies need Tang screening, because Tang screening can help detect the risk of chromosomal abnormalities in test tube babies and provide more comprehensive information and decision-making basis for couples. The risk of chromosomal abnormalities in test tube babies is relatively increased. Tang screening test helps to find high-risk fetuses as early as possible and provides more options for couples. The process of Tang screening examination is similar to that of ordinary pregnant women, including consultation, risk assessment, blood sampling, result analysis and result notification. Tang screening test is of unique significance for IVF, which can reduce the anxiety and pressure of couples and ensure the healthy growth of IVF.
