## Indications for use
The cobas u 601 urinalysis test system is comprised of the cobas u 601 urine analyzer and the cobas u pack. The cobas u 601 urine analyzer when used with the cobas u pack is a fully automated urinalysis system intended for the in vitro qualitative or semi- quantitative determination of urine analytes, including pH, leukocytes, nitrite, protein, glucose, ketones, urobilinogen, bilirubin, color and erythrocytes, as well as clarity. These measurements are useful in the evaluation of renal, urinary, hepatic and metabolic disorders. This system is intended to be used by trained operators in clinical laboratories. The cobas u pack is a cassette loaded with cobas u 601 test strips for the in vitro qualitative or semi-quantitative determination of pH, leukocytes, nitrite, protein, glucose, ketones, urobilinogen, bilirubin, color and erythrocytes in urine with the cobas u 601 urine analyzer. These measurements are useful in the evaluation of renal, urinary, hepatic and metabolic disorders.
