Test Code UMACRS Urinalysis with Reflex Testing LAB3914

Important Note

Microscopic exam of urine sediment is performed under the following criteria:

  • Clarity is cloudy or turbid
  • Positive for blood
  • Protein >=30 mg/dL
  • Nitrite positive
  • Leukocyte esterase positive

A Urine Culture is performed under the following criteria:

  • WBC >5/hpf
  • Moderate bacteria
  • Nitrite positive
  • Leukocyte esterase positive

Test Method

Reagent Impregnated Strips; N-Multistix 10 SG, Siemens
Healthcare Diagnostic

 Wet Prep Microscopy

Specimen Requirement

10 mL of urine is required. First morning void is
recommended.

Additional Specimen Collection Information
