Urinalysis, Routine

Detect abnormalities of urine; diagnose and manage renal diseases, urinary tract infection, urinary tract neoplasms, systemic diseases, and inflammatory or neoplastic diseases adjacent to the urinary tract.

Insufficient volume may limit the extent of procedures performed. Metabolites of Pyridium(R) may interfere with the dipstick reactions by producing color interference. High vitamin C intake may cause an underestimate of glucosuria, or a false-negative nitrite test. Survival of WBCs is decreased by low osmolality, alkalinity, and lack of refrigeration.
