For a standard test (testing one possible father with one child), a highly qualified laboratory should return DNA paternity test results within 1-2 business days of receiving all samples. While the best DNA labs can produce results in 1-2 days, others can take 3-12 weeks (or even more) to complete the test, and at a higher cost!
Waiting for results for this potentially life-changing test is stressful, and everyone, of course, wants a paternity test result sooner rather than later. Therefore, DDC provides ultra-fast service without sacrificing accuracy; Our testing fees for both at-home paternity tests and legal paternity tests include sample processing and result availability within two (2) business days, with the test report immediately posted on our website so our clients can immediately see the result. Our clients also have the option to choose, for an additional fee, tests with results available within one day or even on the same day the samples are delivered to the laboratory. For non-invasive prenatal paternity tests, results can be available to the customer in as little as three (3) business days.

- Is it possible to speed up a DNA test?
Anyone planning to undergo genetic testing is wondering how long it takes to do a DNA test?
There is no clear answer to this question. The timing of DNA analysis depends on the type of study and the number of markers analyzed (tandem repeats). It also matters where exactly the test is performed - on site or sent to another laboratory. In the second case, part of the time is spent on delivering biological material. For example, if we are talking about the study of ethnic origin on the mother’s side, DNA analysis can take more than a month; establishing paternity takes from 4 to 9 days.
But, as a rule, most DNA tests are completed in 7-9 business days.
What determines the accuracy of the analysis?
Our company conducts testing using the polymerase chain reaction method, in which the desired gene regions are isolated and copied many times. The technique allows the use of any suitable biological sample: blood, nails, hair, clothing and personal hygiene items. PCR allows you to determine with high accuracy all the biocomponents contained in the sample.
Due to the fact that genetic testing is very sensitive, it is necessary to maintain the purity of the sample from the moment of collection until the moment of analysis in the laboratory. In order to be confident in the accuracy of the DNA paternity test, you need to contact already proven professionals. Our company guarantees the quality of testing results and offers:
- Services of the newest laboratory, opened in 2021.
- Testing and research are carried out using the most modern equipment.
- We employ some of the best professionals with extensive practical experience.
- When testing, special primers and reagents are used.
Dependence of the speed of obtaining results on DNA analysis methods
Since DNA testing is a very promising industry, genetic analysis methods are constantly being improved. But despite scientific progress, it still remains a very complex procedure.
In order to “read” a deoxyribonucleic acid molecule, it:
- isolated from the obtained biological material;
- divided into parts, which are painted with fluorescent dyes with different luminescence intensities;
- amplify (repeatedly copy areas that are taken for analysis).
After this, the selected genome regions are analyzed.
The speed of performing these procedures depends on the chosen technique. Currently, sequencing (building DNA structure) is carried out in several ways. The most promising and fastest is automated sequencing using the Sanger method, as well as the new nanopore sequencing technique, somewhat reminiscent of computed tomography.
Instructions for non-standard DNA samples
In case you wish to maintain confidentiality or are unable to take a standard saliva sample from DNA test participants. We can extract DNA from unusual samples such as hair follicles, fingernails, blood stains and handkerchiefs, as well as other items that retain traces of DNA. Note! The probability of extracting DNA from a non-standard sample is not always 100%. If DNA extraction is successful, the accuracy of the analysis will be above 99%.
It is necessary to understand that in some cases the DNA profile may be mixed, because the sample may contain biological traces of several people (this is especially true for household utensils and combs) YOU can provide a slightly non-standard one. samples, so one is not always enough to compile a complete DNA profile.

Is it possible to speed up a DNA test?
As we have already mentioned, how much a DNA test is done depends on the type of research being carried out. But the equipment of the laboratory and the methodology used also play an important role in this process. Therefore, the deadlines indicated by different companies offering genetic research can sometimes differ significantly.
When choosing a laboratory for genetic research, it is better to focus not on the speed of obtaining results, but on the reputation of the company offering such a service. After all, the most important thing is the reliability of DNA analysis.
Our team compiles genetic passports and guarantees high accuracy of the results obtained. Sign up for a DNA test with us to find out everything about the characteristics of your body.
Purpose of genetic testing
Contents (click to open)
In most cases, to establish paternity, written evidence, testimony and photographs confirming the cohabitation of a man and woman during the alleged period of conception of the child are sufficient. If there are not enough of them, at the request of the party, a genetic DNA paternity examination is ordered, the purpose of which is to establish the fact of the relationship between the father and the child.
If DNA testing shows that the man is the biological father, the court will decide to establish paternity, even if he denies it. A woman gets the opportunity:
- Collect child support;
- Collect alimony for your maintenance when the mother is on leave to care for a child under 3 years old;
- Determine the place of residence of the son or daughter, establish the procedure for communication with the father;
- Based on proven paternity, the child will be able to claim the father's inheritance in the event of death.
Important! If a child was born not in an official marriage, but while living together, the father is established only when the mother and father submit an application to the registry office. Otherwise, the documents indicate the patronymic name named by the mother, and a dash is placed in the “father” column. In the absence of a confirmed relationship, the woman will not collect child support, because
officially his biological father is no one
In the absence of a confirmed relationship, the woman will not seek child support, because officially his biological father is no one.
The results of the DNA examination fundamentally confirm the relationship between the man and the child; on their basis, the court makes a decision and appropriate entries are made in the registration documents of the minor.
Features of forensic examination
Not every DNA test result can be included in the case. To do this, you must follow the existing requirements:
- when contacting the diagnostic center, it is mandatory to present the parents’ passports and the child’s birth certificate to establish identity;
- all documents are copied and must be certified by a seal;
- Before collecting materials, all test participants are photographed;
- information about the DNA paternity test is entered into a special protocol, which specifies the time and place of taking biological samples, passport data, the protocol must be signed by an expert and 2 witnesses, certified by a seal.
Failure to comply with any of these points will not allow the results to be accepted for consideration in court. Moreover, the judge himself chooses the diagnostic center to conduct the study, which is where the parties will have to contact.
If, based on the results of the examination, it turns out that the man is the father of the child, then he continues to bear his parental responsibilities. Otherwise, he is exempt from having to pay alimony. Other rights, including inheritance rights, will also be terminated.
