Is the person you think is the father (or mother) the biological parent?
Resolve the lifelong anxiety about parent-child blood relations in as little as 2 days with High-Precision Paternity DNA Testing, delivering accuracy of 99.99% or higher, which is 10 times the international standard.
Resolve unspoken worries about paternity from 24,800 yen (including round-trip shipping and tax).
Leave it to seeDNA Genetic Testing Laboratory, an internationally accredited DNA testing institution.

No mistakes with double-checkingOnly seeDNA has two inspectors analyze the samples twice!
Reporting results after only a single analysis carries a high risk of misjudgment due to human error, which requires caution.
Peace of mind with full refund guaranteeSince 2016, we have had "zero" testing errors or troubles at our Tokyo lab. While our results have overturned those of other companies, there has never been a case where our result was wrong.
In the unlikely event that a DNA test result is incorrect, we will provide a full refund.
Accurate with 10x international standard precisionMinimum guaranteed positive accuracy of 99.99% or higher!*1
Many companies boast about their "maximum" accuracy, but only seeDNA can guarantee a minimum accuracy.
*1: Paternity (Maternity) Probability: An index necessary to confirm biological relationships
Free re-testing if sample is damagedIf a sample is damaged due to an accident during shipping, we will perform a free re-test. seeDNA Genetic Testing Laboratory also covers the round-trip shipping costs, so no additional fees are required.
We can ship under an individual name instead of the company name, or use Poste Restante to receive the kit at your local post office, allowing you to take the test without worrying about others finding out.
If using the dedicated swabs is difficult, various samples like toothbrushes, cigarette butts, chopsticks, or diapers can be tested with the same accuracy as swabs.
We never disclose any testing information to anyone other than the client. We are a Privacy Mark certified genetic testing institution where you can test with peace of mind.
Highest level of testing success rateBasically, we ask you to submit buccal epithelial cells (swabbed from the inside of the cheek) as a sample.
If submitting a swab is difficult, samples other than swabs such as "toothbrushes", "hair", or "cigarette butts" can also be tested. The accuracy of the test does not change depending on the type of sample.
For details on non-swab samples, please refer to here.

This is the success rate for each type of sample that can be used for paternity DNA testing.
The DNA amount required for a single analysis is 1 nanogram, so testing can be performed without any issues as long as a trace amount of DNA remains in the sample.
The main reasons the success rate is not 100% are cases where DNA from multiple people is mixed in the sample or the DNA has completely degraded.

* The video "1. How to collect buccal epithelial cells" mentions "4 dedicated swabs per subject," but the correct number is "2 dedicated swabs per subject."


Even with mutated or damaged samples that cannot yield accurate results at other companies, you can obtain the most accurate results with a minimum guaranteed paternity probability of 99.9999999%. This genetic test uses a patented technology unique to seeDNA Genetic Testing Laboratory capable of analyzing trace and damaged DNA, which is difficult to test with general DNA testing methods used by forensic labs.
For DNA testing using special samples, such as an umbilical cord stored at room temperature since the Meiji era 130 years ago, leave it to seeDNA Genetic Testing Laboratory.
*1: Even High-Precision Paternity DNA Testing provides sufficient accuracy, more than 10 times the international standard.
If clear results are shown in a High-Precision Paternity DNA Test, the results will not be overturned by a Special Paternity DNA Test.

There are two types of High-Precision DNA Testing: "Private Testing" and "Legal Testing".
"Private Testing" is a test performed for the purpose of personal confirmation. We will send you a testing kit, and you will collect the sample yourself.

The requester will fill out an application form, and the test subject will sign a consent form*. Submission of identification documents is not required.

The seeDNA Genetic Testing Laboratory's report, which includes the subject's DNA profile and photos of the tested samples, has a very good reputation for being easy to understand and reliable.
If the subject's DNA profile is not shown, you cannot truly trust whether the test was conducted properly.
Also, without a photo of the sample actually used for the test, you may feel anxious about whether the result is truly from the sample you sent.
With seeDNA Genetic Testing Laboratory, you can confirm with photos and specific numbers that the correct result is derived from the sample you sent yourself.

We explain how to read the result report in a video.
