For hours, walk-ins and appointments.Urinalysis, Complete With Microscopic Examination With Reflex to Urine Culture, Routine
CPT:
81001. If reflex testing is performed, concomitant CPT codes/charges will apply.
Test Includes
Reflex to routine urine culture (equivalent to test 008847). Specimen will reflex to a routine 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
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

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
