Testing documentation

To help reduce court costs and assist in ensuring the admissibility of testing records in disputed proceedings, Quest Diagnostics offers several test document options.

Business record affidavit

Designed specifically to reduce court costs and simplify the admissibility of test results as authenticated business records, an affidavit is typically available within two to three business days of request. This documentation is compliant with federal rules of evidence and includes the external custody and control form and the final lab report.

Comprehensive documentation package

Available within three to four weeks of request, a comprehensive documentation package demonstrates the laboratory’s strict adherence to chain of custody procedures and provides all testing and quality control data, including both screening and confirmation testing.
