Inquiring about children's genetic testing on Taobao and other platforms found that the prices also vary greatly, ranging from less than 100 yuan to as high as 5,000 yuan, making it difficult for consumers to choose. Some institutions also said that due to technological progress, the price of genetic testing is changing with each passing day, and it is difficult to distinguish the price moisture.

Methods of gene detection:
1. Biochemical detection: detect blood, urine, amniotic fluid or amniotic cell samples by chemical means, check the existence of related protein or substances, and determine whether there are genetic defects. 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: directly detect the abnormality of chromosome number and structure, instead of checking the mutation or abnormality of a gene on a chromosome. Usually used to diagnose fetal abnormalities. The common chromosomal abnormality is an extra chromosome, and the cells used for detection are from blood samples. If it is a fetus, cells are obtained by amniocentesis or villus sampling. Dye to make chromosomes stand out, and then observe whether there is any abnormality with a high-power microscope.
