|Test||URINALYSIS REFLEX SEDIMENT + CULTURE|
|Methodology||Chemstrip 9® or 10® / Refractometry / Microscopic Examination, if applicable|
|Description||Includes "Urine Screen, Random Urine". If leukocytes or protein are present in clinically significant amounts or if nitrite or occult blood are positive, or if appearance is not normal, the Urine Screen will be replaced by a "Urinalysis, With Sediment" at an additional charge. In addition, if leukocytes are present in clinically significant amounts or if nitrites are positive, or if sediment shows > 10-20 WBC/hpf or >= 2+ bacteria/hpf, a "Culture, Bacteria, Urine" will automatically be performed at an additional charge. Significant isolates reflex to organism identification and antibiotic susceptibility testing at an additional charge.
NOTE: In some infected patients, microorganisms and WBCs are present in low concentrations and will not be detected by this test. When this occurs, the test will not reflex to culture.
NOTE: Additional testing, Reducing Substances Random Urine, will be performed for patients with a negative glucose who are 2 yrs of age or under at an additional charge.
NOTE: This test, when ordered on Medicare patients, is subject to the National Coverage Determination (NCD) policy "Urine Culture, Bacterial". Please verify that the diagnosis code (ICD-9) you have chosen demonstrates medical necessity for the test as documented in the physician's patient record. The CMS web site or the NorDx Limited Coverage Documentation Guide are available to assist you with this verification. A properly executed Advance Beneficiary Notice (ABN) must be submitted with the specimen if medical necessity is not demonstrated by the ICD-9 code chosen.

The BD Vacutainer® Urine C&S Preservative Plus Plastic Tube available in 13x75mm, 4mL draw (gray top culture & sensitivity tube) is not acceptable for urinalysis.
