Abstract: Results of this study indicated that a protein-negative, blood-negative dipstick result may be used to rule out the necessity for performing a microscopic examination in "routine urinalysis" only if one is willing to accept 13% false-negative results. On the other hand, a protein-, blood-, and leukocyte esterase-negative dipstick result was associated with 1.4% to 3.3% false-negative results. The high sensitivity of the leukocyte esterase— measuring dipstick for microscopically abnormal urine samples was dependent on its ability to detect small numbers of leukocytes only when interpreted<i>five minutes after immersing it in the sample</i>. Various approaches may be used by which these findings could be applied to produce cost savings and also protect the small number of patients who may have dipstick-negative, microscopically positive urine.
