In which situation would additional urine testing be warranted?

Additional urine testing is warranted in situations where there are clear indications of recent substance use or when the urine sample shows abnormalities, such as temperature outside the expected range.

When a patient shows signs of recent substance use, urine testing can help verify or refute those suspicions and ensure safety and compliance in medication-assisted treatment. Significant discrepancies in the expected findings, such as a urine sample that is below body temperature, can indicate tampering or issue with sample integrity, which then necessitates further testing to ensure accurate results.

In this context, both the signs of recent substance use and temperature anomalies are critical indicators that call for further investigation through additional urine testing to uphold the integrity of the treatment process.
