What important detail should be recorded when collecting a random urine specimen?

Recording the actual time of voiding is crucial when collecting a random urine specimen because it provides essential context for interpreting the results. The time at which the urine is collected can greatly influence the concentration of various substances, hormonal levels, and the overall composition of the urine due to factors such as hydration status, food intake, and physical activity. Knowledge of when the sample was taken allows for a more accurate assessment of results, particularly in relation to the timing of any potential tests being conducted.

Other details, while valuable for certain analyses, do not offer the same level of insight into the timing effects on the urine's composition. For instance, the volume of urine, specific gravity, and pH level provide important information about the sample itself but do not relate directly to the timing of the collection in the way that the voiding time does. Therefore, recording the time of voiding is an essential practice that enhances the interpretation of urinary analyses.
