1. An assessment was made of the extent sodium (Na) and potassium (K) intake can be estimated from Na, K and creatinine (Cr) content of a second morning voiding urine (SMU) specimen collected within 4 h after the first voiding upon awakening but before breakfast in 159 clinically healthy, free-living individuals (20-79 years). The SMU and the rest of 24 h urine specimens for a 3-5 day period were collected.2. The following equations for estimating 24 h urinary Na (24HU(Na)V) and K (24HU(K)V) excretions were developed, and the accuracy and the reliability of these equations were evaluated. Estimated value of 24HU(Na)V (mEq/day) = 16.3 square-root X(Na); estimated value of 24HU(K)V (mEq/day) = 7.2 square-root X(K), where X(Na) (or X(K)) = SMU(Na) (or SMU(K))/ SMU(Cr) X predicted 24 h urinary Cr excretion.3. Highly statistically significant correlations were detected between the values estimated and measured for both Na (r = 0.728, P
