The help of genetic testing in the diagnosis and treatment of diseases is mainly reflected in the following aspects:
Diagnosing diseases: Genetic testing can be used to diagnose diseases or risk of disease by detecting DNA through blood, body fluids, or cells. For example, genetic diagnosis can be used to detect Mycobacterium tuberculosis, the new coronavirus, etc.
Risk: Genetic testing can help** an individual's risk of developing a certain disease. By detecting the status of genes, it is possible to detect the risk of various cancers and prevent them in advance.
Pertinence**: Some diseases have a familial genetic predisposition, and genetic testing can find out the causative genes, which can help to target**, such as hypertension, diabetes, etc. Through genetic diagnosis, we can select the ** drug suitable for the patient and avoid drug toxicity
Drug selection: Genetic testing can help doctors choose the right regimen for patients with different types of molecular variants, so as to implement targeted drugs.
Genetic testing has other applications in disease diagnosis and treatment, such as in polygenic genetic diseases, which can find out the causative genes, adjust the lifestyle in a targeted manner, and prevent or delay the occurrence of the diseaseClinically, it can be used to evaluate fetuses that may have a genetic disorder that has not been diagnosed by specific genetic tests for the phenotype in question.
It is important to note that genetic testing is not a panacea, it can only provide risk of disease and possible targeted solutions, and cannot replace other medical diagnosis and methods. At the same time, genetic testing results also need to be interpreted and applied according to the specific situation.
