Urinalysis

Message
A urine microscopic examination will be performed as reflex testing if color is abnormal; protein is  >=10 mg/dL; positive blood, leukocyte esterase, or nitrite.


Test Code
URINALYSIS(BHS)


Alias/See Also
Urinalysis


Includes
A urinalysis includes: specific gravity, ph, glucose, bilirubin, ketones, blood, protein, urobilinogen, nitrite, leukocyte esterase, color, appearance.
A microscopic exam will be performed on urine specimens that yield >=10 mg/dL of protein, positive nitrite, positive leukocytes or positive blood.

Specimens that are grossly bloody, turbid, or viscous will not have chemistry portion of urinalysis reported. They will have color, clarity and microscopic examination performed.


Preferred Specimen
Random urine


Minimum Volume
12 mL


Transport Temperature
Refrigerate


Specimen Stability
Room temperature: 1 hour
Refrigerated (2-8°C): 48 hours

Urines that are allowed to sit at room temperature may undergo pH change and in turn interfere with protein determination.


Methodology
Contact the Hematology Supervisor for method information or chemical principles of each test performed.

Setup Schedule
Daily


Report Available
TAT 1 day

Clinical Significance
Dipstick urinalysis measures chemical constituents of urine. Microscopic examination helps to detect the presence of cells, bacteria, yeast and other formed elements.
