Final answer:
Storing a urine sample at room temperature can lead to changes in specific gravity, color, odor, pH, and the breakdown of cells or other substances within the sample.
Step-by-step explanation:
If a urine sample is stored at room temperature, several changes can be expected as time passes. The specific gravity, color, odor, pH, and the breakdown of cells or other substances within the sample. of urine may be altere d due to the evaporation of water, which would concentrate the solutes. Microbial growth could lead to changes in the color and odor of the urine, potentially making it darker and producing a stronger smell. The pH of the urine may also change, becoming more acidic or alkaline depending on the microbial activity. Furthermore, chemical breakdown of certain substances within the urine can occur, such as the breakdown of urea into ammonia, which can also change the odor. Finally, any cells or casts present in the urine may degrade over time, which can influence diagnostic testing or analysis.
