DNA Testing and Privacy

We do not disclose any information regarding the test or results with anyone besides the original applicant for the test. Your privacy is our priority.

Protecting Personal Information with a Consent Form

For a legal DNA test, an unbiased third-party staff specialist oversees the sample collection and preparation of the paperwork, including the application and consent forms. For personal DNA tests, a consent form is required with the names of all the tested parties (following the guidelines of the Ministry of Economy, Trade and Industry).

This means that there are no legal issues with a father ordering a DNA test to confirm the biological relationship between himself and his child.

DNA tests are now 80% cheaper than they were 10 years ago, and every year the number of requests for DNS tests goes up. Even so, 50% of DNA tests are paternity tests done at the request of the father.

DNA testing and Privacy Protection

If a mother were to send in samples of the man she thought was the father of her baby without his knowing, it would be in violation of the guidelines set by the Ministry of Trade, Economy and Industry.

However, in the case of personal DNA tests intended for private use, it seems it can be difficult to get consent from the husband and get him to provide a cheek swab sample.

As simply asking for a DNA test could be a factor contributing to divorce, in reality there are many cases of a wife having a DNA test done without the husband`s knowledge, providing his toothbrush or cigarette butts for his DNA sample.

For a personal DNA test, it is difficult to confirm the identity and contact information of all test participants. We ask that correct information be submitted on the consent form when requesting a DNA test.

Security Measures

We take several precautionary measures to ensure that our clients feel safe entrusting their DNA testing with our laboratory. Not even the fact that the client has ordered a DNA test is shared.
In order to protect our clients` privacy, no information concerning the test is shared with anyone except the original requester of the test. Even if a test participant contacts our office, case information cannot be disclosed without the express consent of the original requester of the test.

It is possible to have the DNA sample kit and test results sent to a designated post office with signature and ID required pick-up to ensure the client`s privacy.

It is possible to test non-standard samples such as a toothbrush, hair or fingernails

While the standard sample used for testing is a buccal (inner cheek) swab, it is also possible to test a variety of other non-standard sample types such as cigarette butts, semen, a razor, etc.
You can see our (What Can be Used as a Sample?) page to learn more details about sample types. If there is a sample type you do not see listed you can contact us to find out if it can be used.

DNA testing 35 times more accurate than the international guidelines set by the FBI

At seeDNA our DNA testing technology is so sensitive that we can differentiate between 21,000 trillion (2,100,000,000,000,000 or 2.1 quadrillion) individuals. This degree of accuracy is 35 times higher than the international standard set by the Federal Bureau of Investigation, which recognizes DNA testing methods that can accurately distinguish between 600 trillion individuals.

Affordable, Accurate and Timely Results

At seeDNA we use the same methods employed by the FBI and CSI. We do not extract the DNA from the samples before testing, but rather use a direct testing method for DNA analysis by testing the samples themselves directly. This allows for highly accurate results while cutting down processing time and costs.

Direct DNA testing has the same level of accuracy as methods that have extraction first, so rest assured that you are getting the same quality results.

Probability of Re-testing

In the case of non-invasive prenatal paternity testing, if the mother`s blood sample is taken from the 12th week of pregnancy and later, the chance of an unsuccessful test requiring a re-test are quite low. However, for blood samples taken between the 8th-10th week of pregnancy there is about a 10% chance of needing of a re-test.

If 174 SNPs (single nucleotide polymorphisms) are analyzed and even 1 spot is not able to be analyzed clearly then a re-test will be necessary.

Please understand that in order to provide results of the highest accuracy, we require a re-test even in cases where the DNA obtained from all of the alleged father`s and the mother`s blood has been analyzed, and there is 1 spot in the fetus`s DNA that cannot be analyzed.

Costs of re-tests are covered

A sample kit for the re-test sample collection is sent with paid postage for return as well, and all testing fees are covered by seeDNA. Also, rest assured that you will receive your results as soon as possible as all free re-tests are treated as express tests. * Please note that blood sample collection fees are the responsibility of the client.

Since the testing method varies depending on the length of pregnancy, accurate information regarding the length of pregnancy is needed in order to avoid delays in the results of a re-test.
