What is a Legal Special Paternity DNA Test?

"Legal Special Paternity DNA Testing" is a special paternity DNA test that can be used as proof of parentage in mediations, courts, etc., even in cases such as mutations that other companies cannot test.
Unlike private tests where you collect the sample yourself, legal tests submitted to courts or immigration bureaus require a professional staff member to be present during sample collection from the test subjects and to keep a record.

How to Read the Report
Report with Sample Photos and DNA Profiles
Our reports, containing the subject's DNA profile and photos of the tested samples, are highly reputed as easy to understand and trustworthy.
Without showing the subject's DNA profile, you cannot truly trust that the test was conducted properly.
Furthermore, without photos of the actual samples used, you might worry whether the results are truly from the samples you sent.
With seeDNA Genetic Medical Laboratory, you can verify that the results are correct and from the samples you sent through photos and specific numerical data.
Sample Collection Method
A video explains the sample collection method.

"Private Test" vs. "Legal Test"
A "Private Test" is a DNA test where you collect the samples yourself for the purpose of personally confirming biological relationships.
A "Legal Test" is a DNA test for submitting the paternity test results to courts, mediations, or government agencies. It requires ID presentation and sample collection under the presence of a legal professional.
Our legal tests also support the issuance of Ministry of Foreign Affairs certificates (Apostille) and reports in English/Korean, required for submission to mediations, courts, or foreign government agencies.
