As Japan's only testing institution for special DNA testing, we can analyze even damaged DNA.
Feel free to consult us even if testing was not possible at other companies.

OK even if other companies failed to test
Standard testing methods have limitations in confirming accurate results when there are mutations or DNA damage.
While using buccal swabs is not a problem,
for special samples, special paternity DNA testing using a Next-Generation Sequencer is highly effective.
If you need accurate results, trust seeDNA Genetic Medical Laboratories, which guarantees a minimum paternity probability of '99.9999999%'.
With Next-Generation Sequencing,
- ✓1.Samples stored at room temperature for 120 years
- ✓2.Samples exposed to sunlight (UV rays)
- ✓3.Samples treated with chemicals like formalin
- ✓4.Cases with DNA mutations
Accurate results with a guaranteed minimum paternity probability of 99.9999999% or higher.
☑Guaranteed Minimum Paternity Probability of 99.9999999%!
This is not the maximum value, but the minimum guaranteed value of paternity probability.
You can receive testing with world-class accuracy.
☑Cheaper than standard paternity DNA tests from other companies
There are no hidden costs not listed on our website.
Free round-trip shipping, zero installment/deferred payment fees.
☑Peace of mind with full money-back guarantee
In the unlikely event of a testing error, we will fully refund the testing fee.
☑Reliable support with free re-testing
If the sample is damaged due to its condition or transport issues, we will re-test for free※1.
※1: Re-testing will use our designated buccal swabs.
☑Double analysis to prevent errors
Double analysis minimizes human error. seeDNA Genetic Medical Laboratories is the only domestic institution that can report such accurate results.※2
※2: No additional costs, testing period, or extra samples are required.
Test without worrying about surroundings
We can ship using a personal name or utilize post office pickup so you can receive the kit without worrying about others.
If taking samples with designated swabs is difficult, we can test various samples such as toothbrushes, cigarette butts, chopsticks, diapers, etc., with the same accuracy.
We never share testing information with anyone other than the applicant. We are a specialized testing institution certified with the P-Mark for privacy protection.
Comparison with standard paternity DNA tests
Special paternity DNA testing can test samples that are considered difficult to analyze with standard tests due to reasons like DNA damage or mutations.
If using buccal swabs or objects containing human cells, a high-accuracy paternity DNA test is sufficient.

5 Reasons to Choose Us
OK even if third-party DNA is mixed
With 20 times the testing sensitivity of standard paternity DNA tests, even if other DNA is mixed, an accurate paternity relationship can be confirmed if at least 1% of the subject's DNA is detected.
OK even with mutated DNA
This is the only paternity test in Japan using the same testing methods as prenatal DNA testing.
Using this technology, we guarantee accurate paternity testing even for DNA with mutations.
Leave trace DNA testing to us with confidence
We use buccal cells collected by rubbing the inside of the cheek with our designated swabs.
If swabs are difficult to use, any object containing the test subject's DNA, such as a toothbrush, hair, or cigarette butt, can be used for testing.
Testing is conducted by technicians with an average of 10+ years of research experience.
