Urinalysis, Routine With Microscopic Examination on Positives

CPT: 81003
Print Share

Test Details

Test Includes

Color, appearance, specific gravity, pH, protein, glucose, ketones, occult blood, leukocyte esterase, nitrite, bilirubin, and urobilinogen. These tests are done on all routine urinalysis ordered and if protein, leukocyte, occult blood, and nitrites are all negative, microscopic examination is not performed; just the above parameters are reported.

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. Sperm is not reported in routine urinalysis exams. Spermatozoa may be seen in male urine related to recent or retrograde ejaculation. For sperm reporting in males only, order Postejaculatory Urine Microscopic Examination for Sperm [133116].

Methodology

Reagent strip

Specimen Requirements

Specimen

Urine (random)

Volume

10 mL

Minimum Volume

2 mL

Container

Routine urinalysis tube or container, BD urine transport tube, or sterile urine cup

Collection

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

Storage Instructions

Refrigerate

Causes for Rejection

Quantity not sufficient for analysis; improper labeling; tubes with boric acid or tartaric acid (eg, BD gray-top C&S tube); LabCorp red-top C&S tube; Boricon, Bortiex, or Boricult yellow-top C&S tubes; specimen not refrigerated or preserved; specimen more than 48 hours old if unpreserved/nonrefrigerated or more than 72 hours old for BD transport tubes; frozen specimens
