Is genetic testing reliable for diseases?

The genetic history of disease families is caused by the inheritance of disease susceptibility genes, so genetic testing can detect these genetic susceptibility genotypes. Theoretically, the detection accuracy is 99.9999%.

First of all, the concept of genetic testing

Gene is a functional fragment of DNA molecule, the basic unit of genetic information and the most basic factor that determines all biological species. Genes determine people's life and death, are the reasons for health, beauty and longevity, and are the manipulators and adjusters of life. So, where there is life, there are genes. All life forms and decline are determined by genes, including your appearance, height, weight, skin color and personality.

Genetic testing is a technique to detect DNA through blood, other body fluids or cells.

Second, gene detection and diagnosis.

Genetic testing can be used to diagnose diseases and predict the risk of diseases. Disease diagnosis is the use of gene detection technology to detect mutant genes that cause hereditary diseases. At present, the most widely used genetic testing is the detection of neonatal hereditary diseases, the diagnosis of hereditary diseases and the auxiliary diagnosis of some common diseases. At present, there are more than 1000 kinds of genetic diseases that can be diagnosed by gene detection technology.
