Instantly post-collection, the sample's temperature and appearance are assessed. Comprehensive validity examinations check creatinine levels, pH, specific gravity, and foreign substances.
DOT tests are distinguished by splitting samples into two vials for possible future retesting. For non-DOT samples, a single vial suffices.
