Answer 1

To ensure accurate results, refrigerate the urine sample immediately and analyze it within 6 to 12 hours to preserve the urine composition and prevent bacterial growth or chemical changes.

Step-by-step explanation:

To ensure accurate results from a urine sample that has been collected just before an emergency, the best practice is to refrigerate the sample. This should be done as soon as possible after collection, ideally within an hour. The urine should then be analyzed within a 6 to 12-hour window to maintain its integrity and prevent the breakdown of substances within the urine that could affect test results. It is important to note that urine composition can change over time due to bacterial growth or chemical changes, which is why timely refrigeration and analysis are critical for accurate laboratory findings.
