How to do a dna test at home. Looking for a dad: how is a DNA paternity test carried out and how much will it cost? Is it possible to trust the results of a DNA paternity test and how the study is carried out
After genetic technologies became available, many were puzzled - how to do a DNA test at home and what is required for such an event? DNA analysis is a rather complicated procedure, which is carried out in specialized laboratories using high-precision equipment. At the same time, the institution must be accredited, have licenses for the right to engage in this type of activity. The most common standard version of the material that is needed for research is buccal epithelial cells, which are taken by smear on the buccal mucosa. And such a procedure can be done both in the laboratory and independently at home.
How to do a DNA test at home
If a person does not have the opportunity to visit the laboratory, then the question arises - is it possible to do a DNA test at home? Testing itself, as above, carried out exclusively in the laboratory. And it is quite possible to take a smear at home, exactly following the instructions. To do this, you will need a postal envelope, a new pack of cotton swabs and scissors. The best option is to use a special kit, which is available free of charge from Ralzo. Such a standard procedure as DNA paternity test is carried out as follows:- Envelopes and sticks are prepared separately for each person who will participate in testing.
- The envelope is pre-signed with personal information - full name, date, month, year of birth, relationship, date when the smear is performed. In anonymous research, an individual number is put instead of the listed information.
- To take a cell sample from one person, two sticks must be used.
- The fence is made on the mucous membrane oral cavity. To do this, the wand makes at least 20 up and down movements. In this case, the cotton head should be pressed tightly and slightly rotated.
- After taking a smear, the stick should be held in air for about one minute to remove excess moisture.
- Next, the end that the hands touched is carefully cut off with scissors, and the part with the cotton head is placed in an envelope. Here you need to be very careful, try not to touch the inner surface with your hands and use adhesive tape for gluing, but do not moisten it with your tongue.
- All manipulations are repeated and the cells are taken from the other side of the cheek.
- The collected materials are sent for research, after which the client receives an official conclusion on letterhead.
Accuracy of DNA analysis at home
To take a DNA sample at home and not doubt the purity of the samples, you need to use the original set and strictly follow the instructions. Everything else depends on the technology of research and the qualifications of specialists.
We use the most advanced equipment and modern reagents, the study of one sample is carried out twice by experienced experts, which makes it possible to obtain an objective and accurate result that no one doubts. Errors and inaccuracies, even in such complex tests as establishing paternity by DNA during pregnancy, are completely excluded! How to get a DNA test kit at home
Order a free proprietary analysis kit you can directly on our website. If you need consulting assistance, we recommend that you call our specialists, who will tell you in an accessible way how to use the kit and provide any information of interest.
DNA paternity test at home
Even in the most prosperous families, it may be necessary to find out whether a child is really a blood relative of the person who considers him to be the father. In some situations, on the contrary, establishing the degree of relationship is required in order to prove to the man that the baby, whom he does not want to raise and provide for, is in fact his son or daughter.
The only way that allows you to confirm or deny the fact of the closest relationship with a high degree of probability is to conduct a high-tech DNA paternity test at home or in a specialized clinic. Carrying out this procedure requires a sufficient amount of time and an impressive amount of money, so not all families have the opportunity to apply to it.
Meanwhile, there are other, much less reliable methods by which you can determine who is the father of the baby without resorting to complex and expensive research. In this article, we will tell you how to establish paternity without doing a DNA test, and how accurate the result can be obtained in this way.
How to determine paternity without a DNA test?
There are several methods that allow you to find out paternity without a DNA test, for example, such as:
Of course, all these methods are very approximate. If there really is a serious need in the family to determine who the baby is the real father, biological material should be collected and contacted by a specialized laboratory for its study.
Frequently Asked Questions About the DNA Test
How is a DNA test done?
Our laboratory uses the polymerase method chain reaction(PCR method), which replaced the previously used RFLP method because it is more accurate and can be used with small DNA fragments. For this reason, it is not necessary to use blood as genetic material, it is sufficient to use saliva.
The child inherits DNA from the mother (23 chromosomes) and from the father (also 23 chromosomes). Each parent is responsible for half of the child's DNA. Thus, a child (and every person) has 23 pairs of chromosomes. In each DNA section (locus) of a chromosome pair, there are certain DNA fragments (alleles) in each chromosome. A DNA test is done by identifying specific pieces of DNA (alleles) for a specific set of loci in the father, mother, and child. If the mother and father are the child's parents, then two pieces of DNA at each locus in the child's chromosomes must be inherited, one from each parent. Establishing paternity or motherhood is possible using these DNA fragments. More about technology...
What is the accuracy of DNA tests?
A DNA test is the most accurate method of establishing paternity. The accuracy in case of a negative answer is 100%.
The accuracy in case of a positive answer is 99.9+% - 99.99999%. Expert opinion confirming paternity - FATHER- cannot be made with 100% certainty, as there is always a theoretical possibility that there will be a twin brother of the tested father with the same genetic profile. The accuracy of the tests offered by our laboratory is the highest available in the world today.
Can paternity be established by blood type?
This method is not a method of establishing paternity, blood types may coincide by chance. Only DNA testing can confirm or disprove paternity. Calculate the blood type and Rh factor of the child
What standards are used to ensure the accuracy of DNA tests?
Our laboratory strictly adheres to the standards of international accreditations AABB, ISO, CLIA and others. Since we use at least 16 genetic markers, the results are usually quite definite - either 0% or 99.9+%. In difficult cases, when 16 markers cannot provide such high accuracy, the laboratory uses up to 33 markers
What is a buccal swab and is it as accurate as blood?
A buccal swab is taken from the mouth with sterile cotton swabs.
How to do a DNA paternity test at home
To take a smear, you need to rub the stick on the inside of the cheek for 10-20 seconds in a circular motion. The result of a DNA test will be as accurate as a blood test, since the DNA in all cells is the same.
Can regular ear swabs be used for swabs?
For smears it is desirable to use sterile sticks, it is most convenient to purchase a kit for taking smears from our DNA center. However, you can also use ordinary cotton swabs - open a new package before taking the material and remove the cotton wrap from one side of the stick. Use 2-4 sticks for each participant and put in paper envelopes. See instructions for details.
How long can a smear be stored if I take it at home and bring it to you not immediately?
The set with the taken genetic material can be stored for a long time - several months, however, we recommend that you do not delay its transfer for analysis, transfer it within 7-10 days, since the probability of successful DNA extraction decreases over time.
Is it possible to send me a smear kit and results without anyone knowing about it?
We understand the sensitivity of the issue of establishing paternity. The set and results will be transferred to you in the most convenient way for you.
Can a paternity test be done without the mother?
Yes, usually the test is done only for the father and the child. Mother's consent is not required. However, if the mother is also involved in the test, the test may be more accurate in some cases.
What if I want to do a DNA test on another child or another father?
Additional family members can be included in the test - another father, child, for an additional fee, the cost of such a test will be cheaper than performing two separate tests.
At what age can a child be tested for paternity?
Even a newborn can be a participant in a DNA test. Taking a saliva swab with a cotton swab is a painless and non-traumatic procedure. If the child is on breastfeeding, it is necessary that at least an hour has passed since the last feeding.
What happens to the samples after the test?
We destroy samples as soon as the test is done and the results are in. Test participants' data is archived.
How will I receive the test results?
The results can be obtained at DNA centers, or they can be sent by Russian post or any courier service, by e-mail and by phone. You choose the method of issuing results when ordering a test.
How to interpret test results?
In the vast majority of cases, the conclusion contains an unambiguous result. The alleged father is either "excluded" or "not excluded" as the biological father. Each of the 15 identifying loci is analyzed separately, a paternity index is calculated from it, then the individual indices are combined to calculate a "combined paternity index". The higher the combined index, the higher the likelihood of paternity. Read more…
What does the result of a DNA paternity test look like?
The result of a DNA paternity test is a letterhead document with a laboratory seal that contains a conclusion about the likelihood of paternity. When negative result paternity is excluded, its probability is 0%. In the case of a positive result, paternity is not excluded, its probability is 99.9+%. In addition to the conclusion, the document contains the genetic passports of the test persons, that is, information about the DNA structure that is unique for each person.
What is the combined paternity index?
The combined paternity index is a number that represents the likelihood of paternity. The number is calculated based on how common the genetic information found in test subjects is in your race population. The combined paternity index can generate a 99.999% probability of paternity, and even higher. For example, a KPI of 9,999,987 means that the chances of the alleged father being the biological father are 9,999,987 to one.
Is it possible to use the conclusion in court instances?
The conclusion you receive from performing the analysis for your personal use can be used as a basis for filing a claim. Such analysis is done without identifying individuals. Analysis for the court is done with the identification of the participants, only it will have legal force.
Are the results confidential?
Your results are strictly confidential and are issued only to you personally, to the postal or email address you specified. Any information on the analysis is reported only to the customer's telephone number indicated in the order form.
Can the test be done anonymously?
You can, you can specify any names when ordering a test.
Do I need a referral from a doctor or court to order a DNA test?
No, you don't need any referrals, it's your right to know the truth.
Is it possible to do a DNA test if for some reason it is not possible to take a buccal swab?
You can do a DNA test on alternative non-standard DNA samples.
Why are you offering such a low price for a DNA paternity test?
Our laboratory is the largest in the world and thanks to the latest automated equipment, we do more tests per unit of time. So, our goal is to attract as many customers as possible, and not to earn a lot on one. At the same time, the quality of the test is at the level of world standards.
Can a paternity test be done before the baby is born?
Yes, we can do a prenatal paternity test. The analysis that we offer is completely safe for the fetus, paternity is determined by venous blood mother and alleged father. Such an analysis is possible if the gestational age is at least 9 complete obstetric weeks.
Does DNA change after a blood transfusion?
DNA does not change after a blood transfusion. In the case of blood sampling within 2-3 weeks after a blood transfusion, there is a small chance that a mixed DNA profile will be obtained (an undesirable situation). But this is not a problem when taking material from the oral cavity (oral swab - as in our case), or if more time has passed since the transfusion. All donated blood is cleared by this time.
Is it possible to be sure about the result of a DNA paternity test if the closest relative of the alleged father (father, son, brother) can also be the biological father of the child?
In this case, you must inform us that there is such a situation. If it is not possible to test both putative fathers, we will run an extended analysis and calculate the chances that the next of kin may be the biological father. In any case, you can be sure of the result of the analysis.
What happens if I take the material incorrectly myself? Will I need to pay for the analysis again?
In this case, you will have to resubmit the material. You don't need to pay anything.
Why such a fast DNA analysis? In other clinics, it is done for about a month.
Since we do a large number of analyses, material is sent to the laboratory several times a week. Delivery of samples - 2 working days. The analysis itself takes 2-5 working days. If the analysis is urgent, it is sent immediately and runs with the highest priority.
The alleged father does not want to do a DNA test, how do I determine paternity?
For analysis, you can use the material of the father's relatives - parents, children, brothers and sisters. An analysis of grandparents and grandchildren is as accurate as a paternity test.
The alleged father is far away, in another country. How can I do a DNA test?
You can take the material yourself anywhere in the world and send it to us for analysis. It is stored for a long time, several months. You can also use the collection services of any doctors, including representative offices of our laboratory in 168 countries.
DNA paternity testing at home
"Not like you, not like me..?" - as you do not throw out the words from the song, it is unlikely that you will be able to close your eyes to the sad statistics. As studies in the UK show, every 25 man brings up a genetically non-native child, without even knowing it. Of course, I would like to believe that in our country the situation is more rosy, although the sharply increased number of couples who wish to establish paternity and undergo a DNA examination is not very encouraging.
Today, all doubting men can get information about paternity, thanks to an ingenious invention - a home DNA test. What kind of analysis is this, what is needed for its implementation and what is the reliability of the result obtained, we will tell you in this article.
Paternity test at home
When first hearing about a DNA paternity test at home, many imagine something like a mini-laboratory or a device like a pregnancy test. But no, in fact, a home DNA paternity test is called only because biomaterial is taken at home, which is then sent to the laboratory. In fact, this is a special set consisting of sterile sticks, multi-colored envelopes and video instructions with detailed description how to properly carry out the procedure for collecting cells (buccal epithelium) from the inner surface of the cheek. The sampling of biological material is necessarily carried out from the intended father and child, the mother's cells simplify the study, but are not considered mandatory. Having received the buccal epithelium, it is placed in a special envelope and sent to the laboratory, where the DNA of the father and the child is directly compared.
The analysis takes several (2-5) days. The results are reported directly to the customer, as they are confidential information that is not subject to disclosure to third parties and government organizations. The accuracy of this study is almost 100%. It is also worth clarifying that in order to conduct a DNA paternity test at home, the written consent of the mother, father and child (after 16 years) is required.
Undoubtedly, such availability of paternity examination caused a flurry of conflicting reviews. On the one hand, this is an opportunity for every doubting man to establish a relationship with a child, on the other hand, distrust of such a plan can cause a divorce. That is why the decision to take a paternity test should be balanced and mutual.
DNA testing for paternity
Sometimes people need to determine whether they are related to each other by blood. Most often, this examination is carried out in order to prove paternity.
DNA paternity test: no doubt once and for all
Modern technologies allow you to test for paternity by blood, saliva, hair and other so-called biological material. This is an ordinary analysis, which, nevertheless, can greatly affect our lives. DNA paternity testing is done to confirm parental rights, inheritance rights, and sometimes even to check for susceptibility to serious hereditary diseases.
How to do a DNA paternity test?
Obtaining proof of paternity is fairly easy these days. To do this, you need to contact a clinic that provides such services, and take tests of the biological material of the alleged father of the child and the baby himself. The easiest way is to take a smear from the mouth (from the inside of the cheek), while the DNA material is obtained from saliva. Alternatively, you can donate hair (necessarily uprooted), teeth, nails, earwax for examination. A blood test is also suitable for paternity testing, but it is easier for doctors to work with saliva, since a blood test can be uninformative after a transfusion, bone marrow transplant, etc. You will know the result of the DNA paternity test in just a few days. In this case, the test can be negative, when the man is not 100% the father of the child, or positive. The probability of the latter is usually between 70 and 99%. It should be noted that DNA evidence has weight as evidence in court only when the probability of paternity is 97-99.9%.
Paternity test during pregnancy
Sometimes it becomes necessary to do a DNA test even before the birth of a child. This technology appeared relatively recently - before, genetic analysis for paternity was possible only after childbirth.
The test is carried out as follows: the alleged father takes a blood test from a vein, and fetal DNA samples are taken from the mother's blood, where by the 9-10th week of pregnancy, an amount of this material accumulates, sufficient for an examination. There are other methods of sampling the biological material of the fetus, for example, amniotic puncture (taking fluid from the fetal bladder). This method of determining paternity by DNA has the same accuracy, but it is much more dangerous due to the threat of complications and even termination of pregnancy, so doctors usually recommend refraining from such an intervention.

How to choose a DNA test?
Depending on the purpose, there are several different DNA tests: sibling, twin, X-chromosomal, Y-chromosomal, avancular, and so on. Which test is suitable can only be determined by a specialist. To do this, it is necessary to take into account the gender and degree of relationship of the intended test participants, to choose the best option for taking the material provided for research, and many other nuances.
By contacting our center, you will ensure high accuracy of DNA analysis, absolute reliability of research and information confidentiality, convenience, comfort, safety and comprehensive care of professional specialists at any stage of cooperation.
DNA testing is an advanced technique that allows for high accuracy do a DNA test find out the relationship, predisposition to various diseases belonging to a certain ethnic group. This type of research carried out in a certified laboratory "DTL", you can take biomaterial samples both at the Moscow Laboratory itself and at its official representative offices.
At the same time, clients often ask the question: how to do a DNA test at home and what is needed for this? Since samples of buccal epithelium are most often used for analysis, such material can be collected independently. The only condition is to use the recommended materials and strictly follow the instructions.
How to do a DNA test at home
So, Can you do a DNA test at home?? Direct genetic research is carried out in the laboratory by experienced experts. And the sampling of biomaterial is quite possible to carry out independently.
Detailed instructions will help do it quickly and correctly:
- It is necessary to prepare materials - cotton buds and clean paper envelopes for each person who participates in the study. The best way - order a special kit in the DTL laboratory.
- The envelope contains personal information - last name, first name, patronymic, date of birth, degree of relationship and date of sampling of the biomaterial; if the procedure is anonymous, then instead of full name. number is indicated.
- To take a smear from the inner surface of the cheek, one person will need two sticks, from which one cotton head should be cut off.
- IMPORTANT! The cotton head must not be touched by hand.!
- The stick should be carefully taken by the cut end and the biomaterial should be taken from the inner surface of the cheek. To do this, make at least ten up and down movements, trying to firmly press the cotton head against the mucous membrane.
- After a smear, the wand must hold outdoors for about 60 seconds to evaporate excess moisture.
- After that, the sample is placed in a clean envelope, the inner surface of which should also not be touched by hands.
- The procedure is completely repeated, but the smear is already taken from the other side of the cheek.
- When biomaterial samples of one person are collected, the envelope is sealed exclusively with adhesive tape.
Thus, samples of the buccal epithelium are taken for genetic examination. The procedure takes an average of 4-5 minutes., is painless and absolutely safe for adults and children, the collected samples are quite enough for a full-fledged DNA paternity test in Moscow and many other tests.
It should be noted that if it is necessary to paternity test during pregnancy, then this requires not only a sample of the buccal epithelium, but also the mother's blood. You can learn more about this ask our consultants.
