What is seeDNA's genetic testing and DNA analysis?

seeDNA's genetic testing and DNA analysis is a testing service that scientifically analyzes human DNA to reveal disease risks, constitution, talents, ancestral roots, and blood relationships such as paternity. We use the latest DNA analysis technology equivalent to forensic science laboratories to analyze 700 DNA regions. For paternity testing, we achieve a probability of paternity of 99.9999999% or higher.

How long does it take to get the results of a DNA test?

seeDNA's paternity DNA test notifies you of the results in as little as 2 days. We employ a fully automated testing system and double-check system at our in-house laboratory in Japan. If an order is confirmed by 18:00, the test kit is shipped by express delivery on the same day. We are also open on weekends.

What makes seeDNA different from other DNA testing institutions?

There are 6 main reasons why seeDNA is chosen: 1) Testing system based on ISO9001 certification, 2) Japan's only double-check system with zero misjudgments, 3) 10 times the global standard testing accuracy with our own patented technology, 4) Personal information protection with the Privacy Mark, 5) Free retesting and full refund guarantee, 6) Social contribution activities such as identifying unidentified persons and providing free tests for victims of sexual violence.

Can I take a DNA test from home?

Yes, it is possible. At seeDNA, the test is completed simply by delivering the test kit to your home, collecting a sample such as oral epithelium, and returning it. We use privacy-conscious packaging and anonymous shipping, so you can proceed with the test without anyone knowing. Round-trip shipping is free.

What types of tests does seeDNA offer?

We handle over 40 types of tests in 4 major categories: 1) Health/Constitution/Talent tests (disease risk, DNA roots, children's talent tests, etc.), 2) Prenatal genetic tests (NIPT, fetal paternity tests, gender tests, etc.), 3) Blood relationship DNA tests (paternity, sibling, grandparent/grandchild, twin tests, etc.), 4) Forensic science tests (infidelity tests, semen analysis, bloodstain analysis, DNA profiling, etc.).

Private and Legal Testing

There are two types of prenatal and paternity DNA testing methods: "Private Testing" and "Legal Testing".

Private Testing

"Private Testing" is performed for the purpose of personal confirmation.
Customers perform the sample collection themselves.
Everything needed for the test is included in the sample collection kit sent from our company.
No identification documents are required, and there is nothing you need to prepare.
Since we cannot contact test subjects other than the applicant, please confirm the consent of all test subjects yourself.

* If the test subject is a minor, a parent or guardian must sign on their behalf.

- Results can be checked in the test report uploaded to the "Member Page", which will be notified by email.
We can also mail the test report upon request.

Legal Testing

"Legal Testing" is performed for the purpose of proving a biological relationship in mediation, trials, etc.
Please visit our company or affiliated legal offices nationwide in person to collect samples in the presence of specialized staff.
Sample collection by business trip is also available.
Free witness services are available at over 200 affiliated legal offices nationwide.
When collecting samples, we will ask for identification documents and take a photograph of the test subject for identity verification.
One written test report issued by our company is included.
In addition, international certification of the report is also possible.
