Test time for genetic diseases of test tube babies
IVF is an embryo that is fertilized in vitro and transferred to the mother through assisted reproductive technology, which is popular among many couples. However, due to the existence of genetic diseases, some potential parents may worry about whether their children will inherit certain diseases. In the process of IVF, the detection of genetic diseases is very important. So, how long can IVF detect genetic diseases? This problem will be described in detail from several aspects below.
Pre trip genetic counseling
Before IVF treatment, couples usually receive pre departure genetic counseling. This stage is mainly to understand the risk of family genetic diseases through consultation and testing. This process involves a comprehensive assessment of the couple's personal medical history, family medical history and possible potential risk factors. Through this consultation process, doctors can better understand the situation of patients and provide them with corresponding genetic advice.
In the process of pre trip genetic counseling, the doctor will conduct preliminary screening for possible genetic diseases by combining the personal medical history and family medical history of both spouses. If a patient is at risk of genetic disease, the doctor may recommend further genetic testing. This process usually takes place a few months before IVF treatment begins.
Embryonic genetic screening
Embryonic genetic screening is an important part of IVF treatment. By genetic testing of embryos before transplantation, embryos with serious genetic diseases can be excluded, and the health of infants can be improved. Common embryonic genetic screening includes chromosome abnormality detection and single gene genetic disease screening.
Chromosome abnormality detection is usually carried out by means of embryo biopsy, which can detect chromosome number abnormalities, structural abnormalities, etc. This test can exclude embryos with chromosome diseases, improve the health quality of transferred embryos, and reduce the incidence of adverse pregnancy outcomes.
Single gene genetic disease screening is mainly aimed at those genetic diseases caused by single gene mutations. Through gene testing of embryos, we can screen whether there are embryos carrying these mutations. This technology can help couples screen for genetic diseases, select healthy embryo transfers, and reduce the birth probability of babies at risk of genetic diseases.
Neonatal genetic disease screening
Even after pre trip genetic counseling and embryonic genetic screening, there is still a certain risk that the baby born by the patient may carry genetic diseases. Therefore, after the birth of test tube babies, the screening of neonatal genetic diseases is also very important. This screening is usually carried out within a few months after birth.
Neonatal genetic disease screening generally involves genetic testing of blood or saliva samples of infants. This test can screen common genetic diseases, such as phenylketonuria, congenital hypothyroidism, and other possible low-frequency genetic diseases. Through early screening and diagnosis, appropriate treatment measures can be taken as soon as possible to improve the survival and quality of life of children.
Summary
The detection of genetic diseases in IVF is a complex and important process. Pre trip genetic counseling, embryonic genetic screening and neonatal genetic disease screening all play a key role in different stages. These detection methods can greatly reduce the risk of IVF suffering from genetic diseases and improve the health level of children.
It should be noted that the specific operation process of each hospital may be different, and the above only gives an approximate time range. At the same time, for some specific genetic diseases, more special detection methods may also be required. In any case, in the process of IVF, it is very important to fully communicate with professional doctors and test according to doctor's orders.
