The U-AQS dip-and-read test strip is designed to test for protein, blood, leukocytes, nitrate, glucose, ketone, pH, specific gravity, bilirubin, urobilinogen and ascorbic acid (vitamin C) in urine, and can be read visually as well as by using urine chemistry analyzers. It is measured by comparison of test paper attached to a plastic strip with the color chart blocks printed on the vial label and offers results within 1-2 minutes after dipping.
