Medical technology is constantly improving, and more and more high-tech is appearing in our lives, and genetic testing technology is one of them. The development of this technology plays a powerful role in the detection of genetic diseases in newborns and the diagnosis of genetic diseases. It can determine the condition of the disease in the first place and make treatment smoother. 1. Basic Concepts Genetic testing is a technology that detects DNA through blood, other body fluids or cells. It takes the oral mucosal cells or other tissue cells shed by the subject, amplifies their genetic information, and then uses specific equipment to detect the DNA molecular information in the cells of the subject. It predicts the risk of disease in the body and analyzes the various genes it contains, so that people can understand their own genetic information and avoid or delay the occurrence of disease by improving their living environment and living habits. 2. Detection function Genetic testing can diagnose diseases and can also be used to predict disease risks. Disease diagnosis is the use of genetic testing technology to detect mutated genes that cause genetic diseases. Currently, the most widely used genetic tests are the detection of genetic diseases in newborns, the diagnosis of genetic diseases and the auxiliary diagnosis of certain common diseases. Currently, there are more than 1,000 genetic diseases that can be diagnosed through genetic testing technology. Predictive genetic testing is the use of genetic testing technology to detect the risk of disease before it occurs, so as to prevent it early or take effective intervention measures. Currently, there are more than 20 diseases that can be predicted using genetic testing methods. During the test, the subject's genes are first extracted from the blood or other cells. Then, primers that can identify genes that may have mutations and PCR technology are used to replicate this part of the gene many times, and mutant gene probe methods with special markers, enzyme cutting methods, gene sequence detection methods, etc. are used to determine whether this part of the gene has mutations or sensitive genotypes. Genetic testing: refers to a technology that uses methods such as gene chips to detect DNA molecules in the cells of the subject and analyze the pathogenic genes, disease susceptibility genes, etc. contained in the subject. At present, the main methods of gene detection include: fluorescence quantitative PCR, gene chips, liquid biochips and microfluidics technology. 3. Accuracy Probability The genetic history of a disease in a family is caused by the inheritance of disease susceptibility genes, so genetic testing can detect these inherited susceptibility genotypes. In theory, the detection accuracy rate reaches 99.9999%. |
