Storage and handling

  • analyze within 30 mins to an hour, refrigerate for up to 6-12 hours if cannot analyze right away

  • Refrigeration can affect specific gravity so ideal to do before

  • crystals form when urine cools

  • unrefrigerated can lead to bacteria growth, increased pH, breakdown of RBCs and casts
