Urine Tests for Chronic Hypokalemia: When in Doubt, Check Urine-Sodium-to-Chloride Ratio

Cclxx. Clinical Tests for Bilirubin in Urine

THE usual tests for bilirubinuria in routine clinical work are relatively insensitive; that this has long been recognised is shown by the various attempts to introduce more sensitive tests from time to time, but none of these has been widely employed. The object of this paper is to review once more the available methods, and to describe a simple yet very sensitive test which, in the opinion of ...

Overnight urine collections to estimate sodium intake.

This study was undertaken to formulate reliable confidence limits for the relationship between nocturnal and 24-hour urine sodium (Na) excretion for use in population compliance studies. Urine excretions were measured in 12 white and 12 black men at three levels of sodium (Na) intake (10, 200, and 400 mEq/day) for 7 days. Nocturnal Na, chloride (Cl), and Cl determined by titrator stick were all...

Urine albumin to creatinine ratio-response to exercise in diabetes.

Albuminuria was studied in 40 diabetic children before and after a standardised exercise test, and also in 21 normal children; the results are expressed as geometric mean (95% range) of urine albumin:urine creatinine ratio (mg/mg). There was no significant difference between the mean resting albumin:creatinine ratio in the two groups, or between these ratios before and after exercise in the nor...
