What is DNA paternity testing?


Paternity testing is the way to determine whether the father (mother) is the biological father (mother) of a child by examining the characteristics of the sequence of the base pairs in the DNA.
A child inherits the total of 46 DNA chromosomes, from the father's sperm (23 chromosomes) and the mother's egg (23 chromosomes).
A child (human) has 46 chromosomes, comprised of 23 pairs. There is a specific DNA sequence located in each area of each of the chromosome pairs. Investigating the specific DNA sequence in several places makes it possible to prove the biological relationship between father, or mother and the child.
If the tested father (or mother) is the biological father (mother), the pair of DNA sequences located in each of the chromosomes of the child should have been passed down from each parent.
It will be proved that you are biologically the child's father(mother) via the DNA analysis.

We use the ABI Company's Identifilar and check 13 locations which conform to CODIS (The Combined DNA Index System), the international standard of DNA. We investigate 16 locations in total, including two more locations and gender gene locations.
This test has been used internationally and has been adopted in many countries. In Japan, this standard has been used by the police, in court and at University Hospitals.

Our advanced technology has made it possible to proceed this test easily by collecting samples from oral mucosa. It is the same as the normal 16-marker test which is performed in many other companies.

When black squares appear for the mutations that occur rarely, the accuracy cannot be expected. In that case the result will be "uncertain".

However, we can give deliver stability and high precision, even for mutations that occur rarely.
