DNA Profile
We analyze DNA from evidence left at crime scenes using the same methods employed by police and forensic medicine to identify culprits.
Specifically, we extract human DNA from evidence and identify the DNA profile used by forensic science laboratories.
Our world-class patented technology enables accurate analysis even from trace amounts of DNA obtained not only from human tissues like bones, bloodstains, and hair but also from items touched by people such as clothing and cigarette butts.
This makes it possible to scientifically prove evidence of cheating or nuisance behavior.
Full Refund Guarantee
If we report a result that differs from the actual DNA markers in the identified DNA profile, we will fully refund the testing fee.
This is our unique "Peace of Mind Guarantee" system, made possible because seeDNA Medical Research Institute is an ISO-certified international organization.
Even if it's your first time, please use our services with confidence.
Secretly Investigate Cheating/Crimes without Being Noticed
In general DNA testing, buccal epithelial cells are collected by rubbing the inside of the subject's mouth with a special cotton swab.
At seeDNA Medical Research Institute, we can perform testing with top-level accuracy in Japan even on samples that are difficult for other companies to test, such as toothbrushes, cigarette butts, hair, and nails.
We are also a PrivacyMark-certified organization for privacy protection, so those who do not want others to know about the test can use our services with peace of mind.
World-Class Testing Success Rate
seeDNA Medical Research Institute clearly states the testing success rate* for various types of evidence.
To avoid wasting precious evidence, it is important to request testing from a reliable institution that discloses its testing success rate.
At seeDNA Medical Research Institute, we can accurately analyze DNA profiles capable of personal identification even from trace amounts of DNA as small as 1 billionth of a gram.
We have a track record of confirming accurate DNA profiles from umbilical cords stored at room temperature for 115 years.
Please refer to the data below for the actual testing success rate for each sample.
Please feel safe leaving it to seeDNA Medical Research Institute with our solid technology and proven track record.
*The main reason the testing success rate does not reach 100% is due to the mixing of DNA from multiple people in the sample, not because the test itself failed.
Free Retesting
If you are worried about damage to the sample, please don't worry. If the sample is damaged during transportation or storage and no test results can be obtained, we will perform a retest for free and cover the round-trip shipping costs.
As a member testing institution of the Association of Genetic Information (AGI), seeDNA Medical Research Institute provides a secure and reliable testing system.
True, Scary Stories of DNA Testing
Case 1
I asked a detective to investigate an affair, but I was charged three times the amount I was initially told, and in the end, no evidence was obtained.
Case 2
I sent the one and only precious sample, but the results never arrived, and there was no refund at all.
Actually, such troubles are not uncommon.
For those who feel anxious about the test results from other companies, seeDNA Medical Research Institute offers a campaign to provide a DNA retest as a second opinion at a special price.
Even if forensic DNA testing is faked, does it really affect the court ruling?

Social Contribution Activities
Free DNA Testing Support for Victims of Sexual Violence
Since 2021, seeDNA Medical Research Institute has been offering free prenatal DNA testing to women who have become pregnant due to sexual violence to confirm whether the child belongs to their partner.
This initiative aims to alleviate the anxiety of victims and support the creation of an environment where they can face themselves with peace of mind.
Clear and Reliable Reports
In some other companies, test results often arrive as just a single piece of paper.
We have received many voices saying they felt anxious, thinking "Is this all?"
At seeDNA Medical Research Institute, in addition to DNA profile information, photos of the actual samples used are also included in the report.
We also explain specialized information clearly and carefully so that even first-time users can understand the contents with peace of mind.
A QR code is issued for all evidence, and the process from analysis to the creation of reports with photos of the evidence is automated. This makes it possible to minimize the risk of human error.

Frequently Asked Questions
Q.What is DNA profile testing?
A.
DNA profile testing is a test that scientifically identifies DNA marker information to identify an individual by extracting human DNA from evidence. Using the same technology adopted by forensic science laboratories, personal identification is possible even from trace amounts of DNA attached to items touched by people, such as bloodstains, hair, cigarette butts, and clothing(1).
Q.How trace an amount of DNA can be tested?
A.
At seeDNA Medical Research Institute, accurate DNA profiles can be analyzed from trace amounts of DNA as small as 1 billionth of a gram (1 nanogram). With our unique patented technology developed with JETRO support (Patent No. 2022-521759), we have a track record of confirming DNA profiles from umbilical cords stored at room temperature for 115 years(2).
Q.What is the cost and period for DNA profile testing?
A.
The cost is 19,800 yen (tax included) per buccal epithelial (cotton swab) sample, and an additional 33,000 yen (tax included) for samples other than buccal epithelium. The testing period is normally 6 business days (excluding weekends and holidays) to report results. There are no additional costs as round-trip shipping for the test kit is included.
Q.Is there a guarantee if there is an error in the test results?
A.
At seeDNA Medical Research Institute, if the identified DNA profile differs from the actual DNA markers, we will fully refund the testing fee. In addition, if test results cannot be obtained due to damage during transportation or storage, we offer free retesting (round-trip shipping also covered by us). As an ISO9001 certified organization, we thoroughly manage quality(3).
Q.Is DNA profile testing effective as evidence of cheating or crimes?
A.
It is effective. Through DNA profile testing, it can be scientifically proven whether the DNA attached to the evidence belongs to a specific person. seeDNA Medical Research Institute has a track record of requests from the police and courts, and examiners with an average of over 10 years of research experience conduct double checks with two analyses. As a PrivacyMark certified organization, those who do not want the test to be known by others can use it with peace of mind(4).
