Test Method

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

Wet Prep Microscopy

Performance

Testing is performed Monday through Sunday.

Routine orders: Typically completed within 2 hours upon receipt in the laboratory.

STAT orders: Typically completed within 20 minutes upon receipt in the laboratory.

Specimen Requirement

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

Collect the first morning void into a clean specimen container with a tight fitting lid. Label the specimen appropriately with two identifiers, patient name and another identifier, (patient ID number, DOB, etc.) include date and time of collection. Protect the urine from strong light prior to transport. Transport urine collections to laboratory as soon as possible. Urine, protected from strong light, may be stored at room temperature for up to 2 hours. If a delay in transport may exceed 2 hours, refrigerate the specimen for up to 4 hours. Specimens not meeting the above storage criteria may be rejected.

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

  • Positive for blood (Trace or greater)
  • Protein ≥30 mg/dL
  • Nitrite positive
  • Leukocyte esterase positive (Trace or greater)

A Urine Culture is performed under the following criteria:

  • WBC >10/HPF
