To date, no convenient method for its exists, as gold standard 24-hour urine collection cumbersome often incorrectly performed, methods that use spot or shorter collections are not accurate enough to replace standard. aim this study was evaluate correlation agreement between a new uses multiple-scheduled collection. Methods: creatinine ratios were determined four scheduled samples. mean samples each single corrected estimated excretion compared Results: A significant linear demonstrated urinary solute excretions evaluated by any spots better than spots. Bland-Altman plots showed differences these measurements within limits agreement. Conclusion: Four can be used estimation excretion.
