Final answer:
Authorized personnel must follow specific procedures for urine sample collection, including 24 hour collection and proper labeling. Tests like Mosenthal and routine urinalysis provide valuable health information. Stringent practices ensure accurate measurements and prevent contamination.
Step-by-step explanation:
The requirements for authorized medical or custodial personnel to collect a urine sample typically include several steps to ensure accuracy and contamination prevention. Medical exams often include urine tests due to the valuable health information urine can reveal. For instance, the Mosenthal test is used to evaluate renal concentrating ability by measuring the density of urine every two hours with a minimum total volume and specific gravity requirements for healthy individuals.
A 24 hour urine collection may be performed to measure various substances in the urine, like magnesium and calcium, which can indicate various health conditions. Correct labeling, including the patient's name, is crucial for all samples. Furthermore, a routine urinalysis may involve simple tests like visual and olfactory analysis, or more comprehensive methods such as microscopic examination and bacterial culturing, depending on the suspected disorder.
