HelpTest Code URFLX Urinalysis with Microscopic if Indicated
Additional Codes
| EPIC | LAB4898 |
Purpose
Urinalysis is a rapid method of semi-quantitatively examining a urine specimen for the most common chemicals excreted by the kidney. Urinalysis is used for diagnosis and management of renal and urinary tract disease, and for detection of certain metabolic or systemic diseases not directly related to the kidney.
