Types of Relationship DNA Testing

Relationship DNA testing can verify genetic relationships such as parent-child, sibling, grandparent, and other relatives.
There are two types of relationship DNA testing: 'Private Testing' and 'Legal Testing'.

'Private Testing' is a DNA test where you collect the sample yourself, intended to confirm blood relationships personally.
'Legal Testing' is a DNA test intended for submitting relationship test results to courts, mediation, or government agencies.
It requires identity verification and sample collection witnessed by professional staff. Legal testing is conducted at seeDNA offices or over 200 affiliated legal offices nationwide.
