Dipstick test. Urinalysis with microscopy has proven to be an invaluable tool for the clinician. Although transient proteinuria typically is a benign condition, persistent proteinuria requires further work-up. Patients with dipstick results of 3+ or greater may have significant proteinuria; further work-up is indicated. A high sugar content is a marker for. Proteinuria can be classified as transient or persistent (Table 5).21 In transient proteinuria, a temporary change in glomerular hemodynamics causes the protein excess; these conditions follow a benign, self-limited course.34,35 Orthostatic (postural) proteinuria is a benign condition that can result from prolonged standing; it is confirmed by obtaining a negative urinalysis result after eight hours of recumbency. A patient is taking a nephrotoxic drug. Results of her urinalysis with microscopy are shown in Table 4. Verywell Health's content is for informational and educational purposes only.

The presence of a ureteral stent causes mucosal irritation and inflammation; thus, findings of leukocyte esterase with white and red blood cells are not diagnostic for urinary tract infection, and a urine culture is required.
