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.

Gene detection method:
1. Biochemical detection.
Biochemical detection is to detect blood, urine, amniotic fluid or amniotic cell samples by chemical means to check the existence of related protein or substances to determine whether there is genetic defect. Used to diagnose a genetic defect, which is caused by protein imbalance that maintains the normal function of the body. Protein content is usually detected. It can also be used to diagnose phenylketonuria.
2. Chromosome analysis.
Chromosome analysis is to directly detect the abnormality of chromosome number and structure, rather than to check the mutation or abnormality of a gene on the chromosome. Usually used to diagnose fetal abnormalities.
3.DNA analysis
DNA analysis is mainly used to identify genetic diseases caused by single gene abnormality, such as Huntington's disease. The cells used for DNA analysis come from blood or fetal cells.
