Court-admissible testing differs from retail kits in three critical ways:
1. Identity Verification
Every individual must present valid identification.
2. Chain of Custody
Specimens are documented from collection to lab.
3. Certified Collection
Handled by trained professionals.
Without those safeguards, results can be legally challenged.
Accuracy matters. Documentation matters more.
