How to interpret the test results of IVF test items
The IVF test project is to evaluate the health status of IVF and discover possible genetic or other potential disease risks through a series of inspection methods. These inspection items include genetic testing, embryological testing, prenatal screening of pregnant women, etc. After receiving these tests, it is very important for couples to understand how to interpret the test results, because it will provide reference for them to make subsequent decisions.
Genetic testing
Genetic testing is used to assess the risk of genetic diseases that may exist in IVF and provide relevant information and suggestions for couples. These testing items can be divided into genetic counseling, genetic disease screening and single gene disease testing.
First, genetic counseling is a very important step. The genetic counselor will learn the family medical history of both spouses in detail to determine whether they are at risk of family genetic diseases. This will help to carry out more targeted genetic testing for IVF.
Secondly, genetic disease screening is a common genetic testing method. It can test the genes of both spouses to assess whether they carry the risk of some common genetic diseases. If it carries risk genes, IVF may also carry these genes and face corresponding disease risks.
Finally, if the couple has a family history of a genetic disease, single gene disease testing may be recommended. This test can detect whether test tube babies carry specific genetic mutations, so as to take targeted preventive measures.
Embryological examination
Embryological testing is mainly used in the process of embryo selection of test tube babies. It can help couples screen out potential abnormal embryos and improve the success probability of IVF. Embryological tests include preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS).
PGD is a genetic diagnosis for embryos carrying specific gene mutations. This test is very important for couples who have a clear risk of genetic diseases, because it can prevent the transmission of genetic diseases.
PGS is a method of screening embryos for chromosomal abnormalities. It can improve the possibility of successful IVF pregnancy and reduce the risk of miscarriage. PGS will detect whether there are chromosomal abnormalities in the embryo, such as universal chromosomal abnormalities (such as Down's syndrome) and chromosomal structural abnormalities (such as translocation, inversion, etc.).
Prenatal screening of pregnant women
Prenatal screening of pregnant women is a test used to assess possible chromosomal abnormalities and neural tube defects in the fetus. It assesses the risk of the fetus by detecting some markers in the maternal blood sample.
Prenatal screening can help couples understand whether there is a risk of common chromosomal abnormalities in the fetus, such as Down's syndrome, Edward's syndrome and Prader's syndrome. In addition, prenatal screening can also detect the risk of neural tube defects, such as spina bifida and craniomandibular malformations.
It should be noted that prenatal screening of pregnant women is only a screening test and cannot give a diagnosis result. If the screening result is positive, it means that there is a certain risk and further diagnostic testing is required.
Summary
Through genetic testing, embryological testing and prenatal screening of pregnant women, couples can understand the health status and potential genetic disease risks of IVF. These test results can help couples make more intelligent and targeted decisions, such as selective induction of labor, selective embryo transfer, etc. At the same time, they can also take corresponding preventive and therapeutic measures according to the test results to improve the quality of life of test tube babies.
Therefore, it is very important for couples to understand and correctly interpret the test results of IVF test items. They should fully communicate and discuss with professional doctors or genetic consultants in order to better understand the test results and possible risks and preventive measures. In this way, they can make the most favorable decision for the development of IVF.
