Genetic testing is a science and technology, so who needs genetic testing?

1. Minimally invasive DNA prenatal nondestructive testing technology in genetic testing of pregnant mothers is aimed at this group. Only by using the venous blood of pregnant mothers can we know the genetic material of the baby, and then we can detect whether the baby has three chromosomal diseases: Down syndrome (T2 1), Edward syndrome (T 18) and Tourette's syndrome (T 13). The diagnostic rate is above 90%. This examination method prevents the risk of abortion and infection caused by invasive diagnosis. The perfect characteristics of the new DNA sequencing technology ensure the accuracy of the technology, and pregnant mothers can test it in 10 weeks.

So far, there is no reasonable diagnosis and treatment of sex chromosome diseases. Therefore, a better way to reduce the risk of chromosomal diseases in pregnancy is to diagnose, find and solve difficulties according to prenatal genetic counseling and prenatal examination as soon as possible.

2. The gene diagnosis of patients with targeted therapy can help oncologists choose appropriate treatment schemes for patients with different types of molecular structure variation, and then promote targeted therapy drugs.

In the treatment of cancer, the chemotherapeutic drugs used in clinical medicine at this stage do not have the specific invasiveness of cancer somatic cells, so the destructive effect of universal chemotherapeutic drugs on all normal somatic cells (such as nocturnal somatic cells) is the same. ), and the adverse reactions are generally more serious. Targeted drugs are designed and produced for the mutated genes of cancer cells at the molecular structure level of somatic cells. Drugs can selectively act on this kind of cancer cell with mutant gene, making it die nonspecific without destroying all normal cells. Targeted drugs have become popular cancer drugs in clinical medicine because of their remarkable curative effect and few adverse reactions.

However, because targeted therapy drugs are usually only used for common genetic variation, the genetic variation of different cancers and different patients may be different. Therefore, for patients who have been diagnosed with cancer and are ready to apply targeted therapy in advance, it is very important to detect the corresponding genetic conditions before choosing targeted therapy drugs, otherwise the drugs are likely to fail. In targeted therapy, it is also necessary to detect the gene mutation appropriately according to the doctor's advice to see if the drug-resistant gene mutation will occur, which is beneficial for doctors to adjust the targeted therapy plan in time according to the specific situation of patients.

3. People who want to prevent cancer are not only targeted to treat cancer, but also genetic testing can find out the risk probability of an individual suffering from cancer, and then prevent it in advance. However, malignant tumor is a disease caused by a series of gene mutations. Mutations in congenital family genes and acquired susceptibility genes may increase the risk of tumor occurrence and eventually lead to malignant tumors. Therefore, in order to accurately evaluate the status of my gene mutation region and the risk of tumor occurrence, it is necessary to master the two-way screening criteria of heredity and susceptibility genes with both hands. Only in this way can we take preventive and intervention measures purposefully and better grasp the leading position of our physical and mental health.

4. People who have to take drugs for a long time, have a history of serious side effects of drugs, and receive multiple drugs to treat diseases at the same time are the main ways to treat diseases. However, the three toxic drugs, used well, are life-saving tools, and used badly are harmful substances to attack. The White Paper on 20 16 Children's Drug Safety Investigation Report shows that the incidence of drug side effects in children in China is 12.5%, which is twice that of adults and four times that of newborns. The drug harm caused by unsafe and incorrect drug use in children is more serious. Of the 2 1 performers of the famous Guanyin Bodhisattva in the Spring Festival Evening of 2008, 18 will be deaf due to drug abuse. At present, clinicians generally follow the guidelines when using drugs, but the compass is aimed at the crowd, and the individual differences of the body are very large.

Genetic testing can prevent this from happening. According to the interpretation of the content of gene information, we can deeply grasp the individual differences, combine these differences with the characteristics of different drugs for the same disease, and get the most suitable drug type and dosage for individuals. According to this basic principle, not only children, but also patients with cardiovascular and diffuse mental illness can take at least time to choose the most suitable drug from a wide range of drugs while taking drugs. Ji Yun Huikang explained that the evaluation criteria of drugs are divided into multiple levels, and the three-dimensional evaluation should focus on the aspects that I should pay attention to, give users of end products deeper medication guidance, and use drugs more accurately.

There are 6 billion people on the earth who want to know their own characteristics, but everyone is different. For example, he likes to eat coriander, but she is as afraid as poison; He is a fitness wizard, but you just can't run on the playground; She can lose ten pounds a day according to fitness exercise, but you can't lose one pound in ten days ... This is also the characteristic of everyone who makes decisions on the content of genetic information, but most people don't know what other characteristics besides their main characteristics until the last moment of their lives. Genetic testing can help you solve your doubts.

6. People with bad lifestyles, such as staying up late, smoking and drinking, are as sick as a mountain. However, this "mountain" cannot be achieved overnight. The bad habits of staying up late, smoking and drinking are accomplices to this mountain. But many people think they are in good health and never take these trivial things seriously until they get sick. In other words, as the old saying goes, you don't cry until you see a coffin.
