Individual Test Information Including Methodology & Reference Ranges

Reflex to UTI Criteria

Specimen Collection and Preparation

Serum or plasma sample in the following tubes:

  • Serum separator tube (gold or tiger top)

  • EDTA (lavender top) and Lithium/sodium Heparin (green top)

Specimen Storage and Stability

Specimens should be centrifuged and separated within 2 hours of collection.


Store serum or plasma at the following temperatures:

  • Room temperature: Up to 8 hours

  • Refrigerated: 2°C to 8°C for up to 48 hours
