Completion of a recognized Chain of Custody Form (CCF) ensures the sample's integrity from collection through laboratory analysis, legally supporting the test results.
4. Temperature & Validity Checks
Immediately post-collection, the sample's temperature and appearance are verified. The laboratory conducts additional validity checks, including creatinine levels, pH, specific gravity, and adulterant screening.
