Don’t diagnose microhematuria solely on the results of a urine dipstick (macroscopic urinalysis).
|Rationale and Comments:||Microhematuria is defined only on urine microscopy: three or more red blood cells per high-powered field on microscopy of a properly collected urinary specimen. Urine dipsticks positive for hemoglobin should be confirmed with urine microscopy, as false positive dipsticks are common. Performing radiographic and cystoscopic evaluation is unnecessary in the absence of microscopically confirmed microhematuria.|
