Opinions vary regarding the proper urinalysis method and the effect of alterations in urine composition on the urine sediment (1-4). In an effort to improve the diagnostic value of routine urinalysis, we studied the effects of urine pH, osmolality, and centrifugation time on the number of casts. The results showed a highly significant inverse correlation between the urine pH and the number of casts seen. Variation of urinary osmolality or centrifugation time was without significant effect.The effects of urine pH, osmolality,...References1.
