Identity Testing
Preparation & Expectations
What is involved in preparation for the test?
No preparation is needed for identity testing. It is important, however, to document the chain of custody of specimens and the identity of everyone being tested. Picture IDs, court orders, notarized statements, and fingerprinting may be required. Results will not be reliable if the person being tested has had a blood transfusion within several weeks of the testing.
