question 5: what is the use of genetic testing? What are the main contents to be detected? 1. Find the susceptible genes in our body in time and take preventive measures as soon as possible. 2. Genetic testing is a technology to detect DNA through blood, other body fluids or cells. It is to take oral mucosa cells or other tissue cells that have fallen off by the examinee, amplify their genetic information, and then detect the DNA molecular information in the examinee's cells through special equipment to analyze the various genes it contains, so that people can know their own genetic information and predict the risk of diseases, so as to avoid or delay the occurrence of diseases by improving their living environment and habits.
3. Zhongyuan Xiehe genetic testing suggests that you use genetic testing technology to find the risk of diseases before they occur, prevent them in advance, or take effective intervention measures.
question 6: the significance of gene testing. which genes are the code of life, the manipulators and regulators of life? Genes can not only transmit genetic information to the next generation through replication, but also express genetic information. The genetic differences between people determine the differences in birth, growth, old age, illness, death, appearance, personality, habits, hobbies and so on. More importantly, genes are closely related to diseases. Except trauma, almost all diseases can be detected by genetic testing, that is, the adverse factors can be avoided in a targeted manner, so that the disease can not be expressed and the disease can be truly prevented. So,? First, let's understand what genetic testing is. 1. What is genetic testing? Genetic testing is called "disease susceptibility gene testing". It is to extract DNA substance from exfoliated cells in human oral mucosa for specific detection, judge whether it is susceptible to diseases from the genetic point of view, predict the risk of future diseases, give early warning to the risks of common diseases, and provide targeted health intervention guidance. So as to actively improve their living environment and habits, and prevent and avoid the occurrence of major diseases. Second, what is the difference between genetic testing and routine physical examination in hospitals? Routine medical check-ups are usually conducted once every six months or once a year to check whether you are sick now, so as to gain time for clinical treatment. Genetic testing only needs to be tested once for the same project in human life, which is to predict the inherent disease risk of the subjects. Through the guidance of professional doctors, the subjects can pay attention to their usual living and eating habits, prevent the expression of pathogenic genes, and gain time for preventing major diseases. Genetic testing and sampling can be done by scraping the oral mucosa of the subject by the international general method, which is painless, harmless, non-infectious, safe and reliable. It takes 15 working days from sampling to issuing the Genetic Physical Examination/Personalized Health Guidance Report. Third, what is the significance of genetic testing: all diseases are related to genes, which are functional fragments carrying genetic information on DNA molecules and substances that convey genetic information by organisms. Genes dominate life and are the root of life. 1. Predictive medicine: The risk of diseases can be accurately predicted in healthy and sub-healthy periods. 2. Disease prevention: disease = internal cause+external cause. Through the understanding of internal causes, the influence of external causes can be effectively avoided, thus reducing the risk of illness. 3. Health management: If you know that you have a certain disease susceptibility gene through genetic testing, you can actively improve the environment and living habits and do your own health management. 4. Personalized medical service: Through genetic testing, we are reminded which drugs should be used with caution, which not only greatly reduces unnecessary medical expenses, improves the curative effect, but also avoids causing greater harm to the human body. Iv. Significance of genetic testing for people who have already suffered from the disease, genetic testing can help the clinical diagnosis, and can make up for the functional defects caused by susceptible genes according to the carrying situation of susceptible risk genes, so as to carry out corresponding treatment and prevent the further deterioration of the disease. V. Significance of breast cancer risk genetic testing 1. Understand the risk of breast cancer as early as possible: Genetic testing can evaluate the genetic risk of breast cancer by detecting the loci related to breast cancer. Genetic testing shows that those with high genetic risk of breast cancer can avoid the risk factors that induce breast cancer as early as possible and delay or prevent the occurrence of breast cancer. 2. Guide personalized life: Unhealthy lifestyle is also a risk factor for breast cancer, and it is necessary to avoid related unhealthy lifestyle for those whose genetic test results show high risk of breast cancer. Maintain peace of mind, maintain relative endocrine balance, balance diet, avoid adverse environment, and actively treat benign breast lesions. 3. Auxiliary diagnosis of breast diseases: Genetic testing (risk level) can be used as an auxiliary diagnosis method of breast diseases, and the results can provide doctors with a basis for one-dimensional judgment. 4. Guidance on rational drug use: Genetic testing can indicate the sensitivity of individuals to certain drugs and the metabolic ability of poisons, and guide rational drug use, especially the safe use of estrogen-related drugs and the use of drugs related to detoxification and metabolism of human body. 5, help predict the risk of future generations: about 15%-2% of breast cancer patients have a family genetic history.

. What are the main contents to be detected? 1. Purpose:
1. Auxiliary clinical diagnosis: Many diseases have similar symptoms, so it is difficult to make differential diagnosis in clinic and easy to be confused. If the cause of disease is found at the genetic level through genetic testing, it can assist clinicians in differential diagnosis and even correct clinical diagnosis.
For example, Huada Gene conducted a genetic test for a family suspected of "congenital cataract-keratoconus syndrome", and finally found that their family was actually suffering from "vitreoretinopathy" rather than "congenital cataract-keratoconus syndrome" at the genetic level, which helped them correct their clinical diagnosis.
Another example is: There is a special type of diabetes called "monogenic diabetes" (caused by a single gene mutation, it is a Mendel hereditary disease. ) Because of its gene defect, patients are obviously different from patients with type 1 or type 2 diabetes in metabolic characteristics, clinical manifestations and treatment schemes. However, due to the lack of understanding, monogenic diabetes is often mistaken for type 1 or type 2 diabetes. An epidemiological survey in the UK shows that 8% of patients with late adolescence diabetes (MODY) have not been correctly diagnosed. In the study of monogenic diabetes in European and American countries, it is found that 1% of type 1 diabetes and 2-5% of type 2 diabetes are actually monogenic diabetes. Therefore, by screening the pathogenic genes of monogenic diabetes in normal people, especially those with family history of diabetes, gene defects can be found as soon as possible, so as to distinguish monogenic diabetes patients from type 1 or type 2 diabetes patients.
2) Guiding treatment: The effect of treatment is related to many factors. Investigating the external reasons, the differences between people are mainly influenced by genetic factors. Genetic testing can help to realize individualized treatment, improve curative effect and reduce the occurrence of adverse reactions.
3) Carrier screening: Down syndrome is the most common screening. The traditional screening for Down syndrome is carried out by serological screening, and the detection rate is 65%-75%.
