DDC UK strictly follows the chain of custody documentation process for every DNA test we perform. This process helps ensure that our test results will be legally defensible in courts and other government departments, should our clients ever need their results for legal purposes (such as obtaining child support).
The chain of custody process satisfies legal requirements by proving the following:
- The DNA samples were collected by a neutral third party - someone who has no personal interest in the outcome of the test. For many of our clients, the neutral third party is a GP or nurse. Clients may also visit our London office to have their samples collected by a DDC UK representative.
- The tested parties were positively identified at the time of sample collection. To be positively identified, a tested individual must present a government-issued photo ID and be thumbprinted.
- The collected DNA samples were made tamper-resistant. The samples are tamper-taped at the collection site and are posted to our laboratory in secure packaging. Upon arrival at the laboratory, the samples are carefully inspected for any evidence of tampering.
When you attend your DNA sample collection appointment, you will be asked to:
- Present government-issued photo identification for yourself.
- Present identification (such as a birth certificate) for any tested minors for whom you have parental responsibility.
- Be thumbprinted and/or photographed.
- Complete a Client Identification and Consent Form for yourself. If you have parental responsibility for a tested minor, you will be asked to complete a consent form for the child as well.
