Urine may be a waste product, but it contains an enormous amount of information. Well-standardized procedures for collection, transport, sample preparation and analysis should become the basis of an effective diagnostic strategy for urinalysis. As reproducibility of urinalysis has been greatly improved due to recent technological progress, preanalytical requirements of urinalysis have gained im...

BackgroundUrinalysis and urine culture are two of the most commonly ordered tests. A positive test in asymptomatic patients often leads to overtreatment. Antimicrobials for bacteriuria is one common unnecessary treatments. We aimed explore current ordering patterns urinalysis cultures.MethodsThis a substudy multicentre RICAT-trial, successful quality improvement project reduce inappropriate use...

JOHN THOMSON, M.D., D.P.H., D.C.H. (From the Department of Child Life and Health, University of Edinburgh) Introduction In the course of carrying out a series of observations on renal output and the composition of the urine in the newborn period, two cases of dehydration fever were observed. The observations recorded in these two cases deviate so far from the normal, Thomson (1944), that their ...

A complete urinalysis includes physical, chemical, and microscopic examinations. Midstream clean collection is acceptable in most situations, but the specimen should be examined within two hours of collection. Cloudy urine often is a result of precipitated phosphate crystals in alkaline urine, but pyuria also can be the cause. A strong odor may be the result of a concentrated specimen rather th...

It is appropriate to commence this article on the history of urine examination with the words of Auguste Comte (1798-1857), who wrote in Positive Philosophy that "To understand a science it is necessary to know its history".' In this context and with special reference to urine, the most freely accessible of all biological fluids, it is not surprising to know that over the course of history it w...
