Which step ensures specimen integrity for urine drug testing?

Prepare for the CAMLPR Specimen Collection Competency Test. Practice with diverse question sets including multiple-choice and flashcards. Each question includes hints and explanations to help you become proficient before the exam.

Maintaining specimen integrity means preventing tampering, ensuring the right person provided the sample, and keeping the sample in a verifiable state from collection to analysis. Using proper collection procedures ensures the sample is collected correctly and representatively. A tamper-evident container makes tampering or substitution detectable. Verifying the donor’s identity prevents mix-ups. Sealing with temperature checks and documenting chain-of-custody (when required) creates a traceable record and helps confirm the sample hasn’t been altered during transport. Together, these steps uphold the sample’s authenticity and admissibility. Labeling alone doesn’t prevent tampering or misidentification, storing at room temperature doesn’t address these risks, and using any container without verification risks contamination or substitution.
