A kinship testing, more often referred to as the paternity test, detects if a certain individual is the parent of a child.
The process includes the collection of biological material from the parent (father or mother) and the child: a smear of the inner surface of the cheek, blood or other biological sample.
Then DNA is extracted from it and genetic analysis is performed by detecting certain DNA sequences and matching them.
A DNA testing to determine kinship can confirm or deny if the studied individual is really the biological parent of the child. Our laboratory offers a service for detecting direct kinship — motherhood and fatherhood.
To take biomaterial for making a test, you should:
To perform the procedure, you should have:
— Sterile hygienic cotton swabs. The packaging of cotton swabs should be new and not opened earlier. 4 swabs per person.
— A new paper envelope. One envelope for each participant. It is not allowed to use plastic bags, plastic containers and other items.
Before the biomaterial collection write the following information on each paper envelopes:
participant’s full name
date of birth
kinship: father, child, mother
date of collecting biomaterial
Prior to the start of the biomaterial collection procedure, the examination participants (children and parents) must
— not eat anything for at least an hour (not smoke, chew gum, or drink anything except still water);
— rinse the mouth scrupulously with clean water.
Every test participant must take a cotton swab by the end and swipe with a gentle pressure 20-30 times with the other end of the swab on the inner surface of the cheek for scraping off the biomaterial.
In one envelope there must be collected 3-4 cotton tips from every test participant.
In order to prevent mutual transfer of biological material all the samples from different test participant should be kept in separate paper envelopes . Do not use plastic bags.
When the collection of samples is finished you need to cut off and throw away the end of the swab that the participant held with the hand. You should put the other half of the swab in the paper envelope.
You can seal the envelope with a tear-off adhesive strip on it or in some other way.
It`s prohibited to use saliva to seal the envelope.
When the biomaterial collection procedure is completed, call the carrier: +995 32 211 00 50. The envelopes with the biomaterial must be given to the carrier. The carrier will place all the envelopes in one package for transport.
In testing, the sections of the child’s DNA are compared with the sections of the alleged father’s DNA.
These areas are referred to as «markers», and by the presence or absence of coincidences, the blood kinship between the participants is confirmed or denied with an accuracy of 100%.
As a rule, from 15 to 30 DNA markers are examined, in our test there are 26 DNA markers.

DNA is in almost all cells of the organism, therefore, the most available biomaterial is often used — a smear of the inner surface of the cheek (buccal epithelium) or blood. If necessary, any biomaterial can be used, including an embryo biopsy obtained during the IVF cycle.
It is believed that DNA testing is the most precise of the accessible testing methods. The kinship test shows:
When matching particular sites in all individuals, several different options can be discovered — from 7 (for the marker «TPOX») to 39 (for the marker «SE33»). If there are no identical options for two people in certain areas, we can state for sure they are not relatives.
In such a situation, the laboratory guarantees 100% that the owner of the obtained biomaterial is not the parent of the child.
To estimate the chance of kinship, you need to know the frequency of variant occurrence in the population for each site. If you detect one «common» variant in two people, you need to take into consideration how rare each of these variants is among all people, and calculate the chance of kinship.
Thus, the column of the form called «the result interpretation» shows how individual the coincidence between the parent and the offspring is.
Why is the chance of kinship never rounded up to 100%?
Since the quantity of option combinations for all sectors is limited, there is always a chance that two persons who aren`t relatives will have the identical option in each sector. It is also impossible to exclude that a possible parent has a twin brother or sister. Monozygotic twins have the same DNA sequence, so the analysis would not be able to identify which of them is the parent.
The examination result will be ready in
5 days after shipping of the biological material to the laboratory
After the analysis is completed, you will get a form with the result. It will include the information about the test participants (the child and the potential parent) and the conclusion of the laboratory researchers.
In the case if the result is positive, the conclusion will be like this:
“the biological kinship of patient No. 1 (Full name) in relation to patient No. 2 (Full name) cannot be excluded”
The chance of kinship will be given below — with this result, the probability of kinship will be ~ 99.9%.
In the case if the result is negative, the conclusion will be like that:
“the biological kinnship of patient No. 1 (Full name) in relation to patient No. 2 (Full name) is excluded”
The chance of kinship with such a result will be — 0%.
