当验证完整性时，从重复的24小时尿液采集中获得的24小时尿氮为膳食评估的有效性、漏报行为和与不同方法相关的测量误差结构提供了有用的见解。当氮与24小时尿样中的另一种标志物钾结合时，情况尤其如此。虽然收集24小时尿液是一个繁琐的程序，该方法是容易获得和相对便宜。饮食摄入的其他标志物和中等风险标志物也可以在获得的24小时尿液中测量。
When validated for completeness, 24-h urine nitrogen obtained from repeated 24-h urine collections has provided useful insights into the validity of dietary assessments, underreporting behaviors and the structure of measurement errors that are associated with different methods. This is particularly so when nitrogen is combined with another marker in 24-h urine samples, potassium. Although the collection of 24-h urine is a tedious procedure, the method is readily accessible and comparatively inexpensive. Other markers of dietary intake and intermediate risk markers may also be measured in the 24-h urine that is obtained.
