Important Note

*This test is orderable in Cerner as Urinalysis Reflex Microscopic, Culture if

Methodology

Colorimetric Reflectance/Microscopic Evaluation/Culture

Includes pH, specific gravity, leukocyte esterase, protein, glucose, nitrite, ketones, urobilinogen, bilirubin, and blood.

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

Culture will be performed when any 1 of the following criteria is met:

1. Leukocyte esterase is positive

2. Nitrite is positive

3. Blood is positive on dipstick and >3 WBC/hpf

4. Protein is positive on dipstick and >3 WBC/hpf

Performing Laboratory
