What is the proper storage condition for a 24-hour urine specimen?

• A. At room temperature
• B. Exposed to light
• C. In a refrigerator
• D. At body temperature

Answer: (C)

The proper storage condition for a 24-hour urine specimen is in a refrigerator. Keeping the specimen refrigerated is crucial because it helps preserve the integrity of the urine for accurate analysis. Room temperature can lead to the breakdown of certain components and possible growth of bacteria, which can alter the results of the tests conducted on the sample. Exposure to light can also be detrimental, as some substances in urine may degrade when exposed to light. Storing the specimen at body temperature is inappropriate because it can promote bacterial growth and could compromise the analysis. Therefore, refrigeration is essential to minimize changes in the composition of the urine and to ensure reliable test results.
