As a general test, urinalysis is frequently assigned to the less experienced personnel. Each of these factors enhances the need for standardized procedures and methods to assure accuracy and consistency of results. Factors that contribute to variance include:

• Sample collection.
• Centrifugation.
• Dilution and resuspension of urine sediment.
• Microscopic examination.

Nancy Brunzel recently discussed these and other factors in her article, “Is Your Routine Urinalysis Test Standardized”, published in the August 2002 issue of Advance for Administrator’s of the Laboratory. Ms. Brunzel argues that the only mechanism to assure accuracy in your urinalysis program requires established protocols for all phases of urinalysis testing. To support your efforts, Hycor Biomedical offers the only complete set of control and disposable products that makes standardization of routine urinalysis possible.
