## Resource

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The mandatory temperature range (90-100°F) and 4-minute timeframe for urine drug screens. - Why an unbroken chain of custody is legally critical and what constitutes a "broken" chain. - The difference between the collector's role (temperature check) and the lab's role (creatinine/specific gravity check) in detecting adulteration. - The specific triggers, like an out-of-range temperature, that require a directly observed collection. - A simple mnemonic (T-C-C: Temperature, Chain of Custody, Creatinine) to remember the key validation steps.
