How to do genetic testing, what are the benefits?

Simply put, genetic testing is to draw a tube of blood or simply use saliva and hand it over to the genetic testing company; To put it bluntly, it's a long story. The detection purposes are different and the methods are different. After DNA (gene) in blood or saliva is extracted by reagents and instruments, follow-up experiments, sequencing, PCR or gene analysis are carried out according to the user's purpose. Each method can produce a book, which suggests understanding molecular biology. \ x0d \ x0d \ What are the benefits of genetic testing? \x0d\ At present, genetic testing is confusing, including health prediction, talent prediction, tumor detection, prenatal detection and even paired detection. At present, \x0d\ 1) is used to assist clinical diagnosis: if Y chromosome deletion, fragile X syndrome, irregular life or pathological changes may lead to infertility, gene detection can assist diagnosis. \x0d\2) Guided treatment: Genetic testing is helpful to realize individualized treatment, improve curative effect and reduce the occurrence of adverse reactions. For example, the genetic test results of colorectal cancer can guide doctors to use drugs, whether chemotherapy or not. \x0d\3) Carrier screening: Down syndrome is the most common screening. The accuracy of previous serum tests was low (70% accuracy), and the risk of amniocentesis was too high. Non-invasive DNA detection makes up for the shortcomings of these two tests, which is accurate and safe. \x0d\4) Guided fertility: The results of genetic testing can be combined with different genetic patterns of diseases to guide fertility through genetic counseling. Help to give birth to a healthy baby through prenatal diagnosis (after natural pregnancy) or IVF combined with pre-implantation screening or diagnosis. \x0d\\x0d\5) Provide accurate matching information for hematopoietic stem cell transplantation \x0d\6) Guide life: Genetic testing of susceptible diseases can infer the risk of a certain disease in the future by detecting genes, and know the prevention in advance, such as genetic testing of breast cancer.
