Gene detection technology is a technology to detect DNA through blood, other body fluids or cells. It is to do molecular level detection on the basis of cell level inspection. Gene detection is a method to take the peripheral venous blood or other tissue cells of the tested person, amplify their gene information, detect the DNA molecular information in the tested person's cells through specific equipment, and analyze the gene types, gene defects and normal expression function, so that people can understand their own gene information, Identify the cause or predict the risk of a disease.
