Subtopic 2 Summary

Results of the chemical examination of urine can give a physician a more complete picture about the underlying disease or condition of a patient. Variations in the normal parameters of pH, glucose, protein, ketones, bilirubin, blood, leukocyte esterease, nitirites, specific gravity, and urobilinogen can often assist in giving directionto the physician on how to proceed with a patient's diagnosis or therapy. For best results of chemical examination of urine, the specimen should be evaluated by closely following the manufacturer's directions.
