Test Code 8646 Urinalysis (Reflex to Microscopic & Culture)

Important Note

Chemical Includes: pH, Specific Gravity, Leukocyte Esterase, Protein, Glucose, Nitrite, Ketones, Urobilinogen, Bilirubin, and Blood.

Microscopic evaluation is performed if leukocytes, nitrites, blood or protein is positive.

A culture is performed if the sample is positive for leukocyte esterase or Nitrite, or has a white blood cell count of 5 or more per high-powered field.The culture will be cancelled if greater than 10 epithelial cells per high-powered field are observed.

First morning clean-catch voided urine is preferred. 

Purpose

Detect abnormalities of urine; diagnose and manage renal diseases, urinary tract infection, urinary tract neoplasms, systemic diseases, and inflammatory or neoplastic diseases adjacent to the urinary tract.
