2. Genetic testing can guide cancer treatment and individualized medication. Cancer is essentially a complex polygenic disease. After gene mutation, the growth and proliferation of normal cells will be out of control, and then turn into cancer cells, eventually leading to cancer. Through genetic testing, we can not only realize the molecular typing of cancer and clarify the mechanism of cancer occurrence and development, but also guide the formulation of individualized treatment plans, improve the efficacy of anti-tumor drugs and reduce the occurrence of adverse reactions. In addition, the side effects and dosage of antithrombotic drugs, lipid-lowering drugs, antihypertensive drugs and antiepileptic drugs can be evaluated by detecting the related sites of these drugs.
3. Genetic testing can also screen carriers and guide prenatal and postnatal care. Screening the genes related to common genetic diseases can find the carrying status of pathogenic genes as soon as possible and analyze the genetic risks of offspring. At the same time, for the indications related to gene diagnosis before embryo implantation, embryos with normal genes can be selected from in vitro fertilization for embryo transfer to give birth to healthy next generation.
