What are the methods of IQ gene detection?

Gene detection methods: biochemical detection, chromosome analysis and DNA analysis.

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.

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.

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.
