More info

These discreet samples can be used for our complete range of DNA tests, including our standard home paternity test, however they are not normally applicable for legal DNA tests due to the chain of custody requirements.

Situations where forensic tests may be used include cases where the alleged father is deceased, but biological samples such as hair or fingernails are available. Hair DNA testing is one of the more commonly requested service. We recommend that you contact our technical team to discuss your case and quote you accordingly.

The list below highlights our complete range of discreet samples that may be submitted for testing, the additional cost per test as well as the expected DNA extraction success rate per sample. Discreet samples terms and conditions should also be reviewed prior to sending the samples.

• Chemicals to which the sample has been subject
• Temperature
• Storage
