Test Includes

Reflex to comprehensive urine culture (equivalent to 008086). Specimen will reflex to a comprehensive urine culture if any one of the following criteria is present:

1. Positive nitrite on reagent strip

2. Positive leukocyte esterase on reagent strip

3. >5 WBC/hpf on urinalysis microscopic examination

4. ≥Moderate bacteria on urinalysis microscopic examination


Expected Turnaround Time

2 - 5 days

Specimen Requirements


Specimen

Urine (random)


Volume

Urinalysis: 3-9 mL (Vacutainer® red/yellow urine transport tube) (preferred) or 2 mL or greater (non-preserved urine); Culture: to fill line on Vacutainer® gray-top culture transport tube


Container

Vacutainer® red/yellow urine transport tube (preferred) or urine bottle/urine transport tube (non-preserved) and Vacutainer® gray-top urine culture transport tube with preservative or sterile cup for both assays


Collection

A voided specimen is usually suitable. If the specimen is likely to be contaminated, a clean-catch midstream specimen is desirable.


Storage Instructions

Vacutainer® red/yellow urine transport tube: room temperature for up to 72 hours

Urine bottle/urine transport tube (non-preserved): room temperature up to 2 hours and refrigerated up to 48 hours

Vacutainer® gray-top urine culture transport tube: maintain at room temperature


Causes for Rejection

Urinalysis ONLY: quantity not sufficient for analysis; improper labeling; tubes with boric acid or tartaric acid (e.g., BD gray-top C&S tube); Labcorp red-top C&S tube; Boricon, Bortiex, or Boricult yellow-top C&S tubes, urine transport tube with Triclosan; specimen received in Vacutainer® red/yellow urine transport tube more than 72 hours old; specimen received in urine cup stored at room temperature greater than 2 hours old; specimen received in urine cup refrigerated more than 48 hours old; frozen specimens; Vacutainer® red/yellow urine transport tube less than 3 mL or greater than 9 mL

Culture ONLY: quantity not sufficient for analysis; improper labeling; specimen received in urine cup stored at room temperature greater than 2 hours old; specimen received in urine cup refrigerated more than 48 hours old, frozen specimens


Test Details


Use

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.


Limitations

Insufficient volume may limit the extent of procedures performed. Metabolites of Pyridium® may interfere with the dipstick reactions by producing color interference. High vitamin C intake may cause an underestimate of glucosuria, or a false-negative nitrite test. Survival of WBCs is decreased by low osmolality, alkalinity, and lack of refrigeration.


Methodology

Reagent strip with light microscopy
