How is the DNA testing process done?

According to experts, DNA testing is a method of identifying blood lines with an accuracy of nearly 100%.

At the center of DNA analysis and genetic engineering, the testing process will start from sample collection.In it, DNA can be extracted from different samples such as fresh blood, dry blood, cells behind cheeks, mouthwash, umbilical cord, nails - feet, hair root, beard root, amniotic fluid or remains.Samples can be taken on the spot or mailed by post.

Samples after collection will be transferred to the extraction room to carry out DNA extraction.The steps must be ensured in a sterile room with strict temperature and humidity conditions to avoid the impact of the environment on the end result.According to genetics, a body's DNA inherits half from the father and half from the mother, specifying the individual characteristics of each individual.

After the DNA is extracted, the technicians will perform a specific DNA replication PCR (used to amplify a short piece of DNA).DNA testing is to determine if the right child receives the DNA of the father or mother.

After that, DNA will be introduced into the capillary electrophoresis system to analyze and solve DNA sequences automatically.

At the results analysis room, the DNA data generated from the explanation machine in the form of diagrams will be read on the specialized software to produce the final result.Professor, Dr. Le Dinh Luong, Chairman of Vietnam Genetics Association, said that DNA testing and analysis not only identifies father-son relations, but also identifies all other blood relations such as you - me, uncle - grandchild, grandfather - grandchild, grandmother - grandchildren, pedigree.These analytical results are nearly 100% accurate with 100% positive and negative cases.

The end result is only delivered to the person directly signing the application, depending on the analysis.With the blood relation analysis model of normal father-son, mother-child system up to 4 days, the minimum can have results after 4 hours, equivalent to 4-7 million VND.
