Only 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.

seeDNA Genetic Testing Laboratory Logo IconPeace of mind with full refund guarantee

Since 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.

seeDNA Genetic Testing Laboratory Logo IconFree re-testing if sample is damaged

If 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.

seeDNA Genetic Testing Laboratory Logo IconTest with privacy

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.

seeDNA Genetic Testing Laboratory Logo IconHighest level of testing success rate

Basically, 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.

Success rate of Paternity DNA Testing

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.

seeDNA Genetic Testing Laboratory Logo IconHow to collect a sample (Video Guide)

* 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."

seeDNA Genetic Testing Laboratory Logo IconTesting OK even with damaged/degraded samples

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.

What is Paternity (Maternity) Probability?
What is Paternity (Maternity) Probability?
It is a genetics term indicating the reliability of a DNA test, not the probability of a parent-child relationship.
A probability of 99.9999999% means "it is almost 100% certain that there is a biological parent-child relationship."
It is theoretically impossible to produce a value of 100%, and there is no way to deny a result obtained with a probability of 99.9%.
Note that the international standard for recognizing a blood relationship is set at 99.9%, and if a biological relationship is not recognized, the probability is 0%.

seeDNA Genetic Testing Laboratory Logo IconWhat is Private Testing?

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.
