The CPT codes provided by GML are based on AMA guidelines and are for informational purposes only.

Test includes: 

Color, clarity, specific gravity, esterase, nitrite, pH, protein, glucose, ketone, urobilinogen, bilirubin, blood, and microscopic (if indicated by lab criteria: blood/esterase/nitrite positive. Protein >=30 mg/dL; Clarity - not clear).


Methodology: 
Colorimetric and microscopic examination
Synonyms: 

Urine chemistry with reflexive microscopic if indicated, UAC


Clinical significance: 

Routine dipstick urinalysis with microscopic examination of formed elements may be useful in assessing the renal and metabolic status of the patient.
