What items need to be checked for IVF?
IVF refers to the babies born through IVF and embryo transfer technology. In order to ensure the health and development of children, IVF needs to carry out a series of inspection items in the whole process. These projects mainly include genetic examination, reproductive system examination, pre pregnancy screening and fetal development monitoring.
Genetic examination
The purpose of IVF genetic examination is to screen and eliminate possible genetic disease risks. These genetic diseases may come from factors such as parents or close relatives' marriage. Doctors will carry out gene testing and screening for diseases related to couples of childbearing age according to their parents' genetic status. Common genetic diseases include chromosome abnormalities, gene mutation and genetic metabolic diseases. These tests can help doctors determine whether patients are suitable for IVF technology.
Chromosome abnormality inspection is mainly used to detect whether the chromosome number and structure of the embryo are normal to exclude the embryonic dysplasia caused by chromosome abnormality. Gene mutation test is mainly used to exclude embryos with genetic risk of single gene disease. The examination of genetic metabolic diseases is mainly to check the risk of metabolic diseases, such as phenylketonuria, congenital hypothyroidism, etc.
Reproductive system examination
Before IVF, women need to carry out a series of reproductive system tests to ensure that their reproductive system functions normally. These examinations include the examination of uterine morphology, endometrial thickness, ovarian function and prolactin level. The size and shape of the uterus can be observed through B ultrasound and other techniques to determine whether it is suitable for embryo implantation. Endometrial thickness examination can evaluate the development and preparation of endometrium. Ovarian function test is mainly used to judge whether the ovary ovulates normally and produces healthy eggs. It is usually measured by blood test and ultrasonic technology. The examination of prolactin level can exclude abnormal ovulation caused by the increase of prolactin.
Pre pregnancy screening
Pre pregnancy screening is to assess whether there are chromosomal abnormalities in embryos, such as Down's syndrome, trisomy syndrome, etc. Common prenatal screening items include non-invasive prenatal gene testing, amniocentesis and chorionic biopsy. Noninvasive prenatal gene testing can accurately detect the presence of chromosomal abnormalities by extracting fetal genetic material from maternal blood for analysis. Amniocentesis and chorionic villus biopsy are to obtain tissues from the fetus through puncture sampling for examination, which can confirm chromosomal abnormalities and other hereditary diseases.
Fetal development monitoring
Once IVF is successfully pregnant, regular fetal development monitoring is required during pregnancy. These monitoring items include ultrasound examination, fetal heart monitoring and prenatal blood testing. Ultrasonic examination can observe the size, shape and development of the fetus, evaluate the function of the placenta and the amount of amniotic fluid. Fetal heart monitoring is mainly used to assess the health status of the fetus through the electrical activity of the fetal heart. Prenatal blood test can detect biochemical indicators in the blood of pregnant women, such as Down's syndrome and neural tube defects. These monitoring projects can detect fetal abnormalities in time to ensure the safety of pregnant women and fetuses.
To sum up, IVF needs genetic examination, reproductive system examination, pre pregnancy screening and fetal development monitoring in the whole process. These tests can reduce the risk of the baby before birth and ensure the health and development of the baby.
