4、Record intake and output of fluids. The normal day output (8:00 a. m. to 8:00 p. m ) is 23 times the normal night output.This ratio is changed in renal disease, in some cases of heart failure, and in hyperaldosteronism .,Proteinuria:The presence of protein in the urine indicates increased glomerular
5、 permeability and some degree of diminution of tubular reabsorption of protein. It appears in many types of renal disease. Slight proteinuria is seen in congestive heart failure, infectious diseases, and after a heavy meal，and in some cases is associated with prolonged standing (orthostatic(直立的) pro
6、teinuria) or with vigorous exercise.,Lesson Four Urinalysis in Testing Renal Function,Casts:Casts result from precipitation of protein in the tubules. Waxy and fatty casts are suggestive of nephrosis. Pus cells:These are seen in large numbers in any genitourinary infections. (Women should cleanse th

9、n Four Urinalysis in Testing Renal Function,Bacteria:Bacteria in the urine may be specific for infection, as in renal tuberculosis, pyelonephritis , cystitis.,Lesson Four Urinalysis in Testing Renal Function,Collection and preservation of urine for analytical testing must follow a carefully prescrib
10、ed procedure to insure valid results. Laboratory testing of urine generally falls under three categories, i. e. chemical, bacteriologic, and microscopic examination. There are three kinds of collection for urine specimens: (1) random; (2) timed , and (3) 24-hour total volume.,Collection of Urine for
11、 Screening Purpose,Random specimens are collected at any time. Test results for a random collection are expressed per unit volume if the result is a quantitative analysis. Much reporting of testing on a random collection is expressed as “positive” or “negative”, indicating the presence or absence of
12、 a particular constituent, such as glucose. A randomly collected urine specimen is often more convenient for the patient and will be suitable for most screening purpose.,Collection of Urine for Screening Purpose,Probably the best specimen for routine examination is the first morning voiding, fresh,
13、concentrated, with an acid PH. If the urine is dilute, small but pathologic increases in content of protein, sugar, red blood cells, white cells, and casts may be missed. Alkalinity and hypoosmolality hasten dissolution of casts and red cells. If specimens cannot be examined immediately, those with specific gravity less than 1.010 should probably be recollected if possible, especially if they are alkaline.,
