Test Name Alias

UA | UA with micro | UA with microscopic | 8715

Interface Order Alias

10067

Clinical Information

Refrigeration of urine inhibits bacteria growth but does not prevent the lytic effects of low specific gravity or alkaline pH. Urine crystal formation may be induced by refrigeration.

Ordering Instructions

Please indicate source, i.e. CCMS (Clean Catch Mid-Stream), nephrostomy, straight catheter.

 

Effective 11/17/2021: When an order for Urine Culture [LAB239] and Urinalysis, do Culture if indicated [LAB348] is placed in the same encounter, these labs will update at the time of collection to an order for Urine Culture [LAB239] and Urinalysis [LAB2111180] to decrease duplicate urine cultures. 

Collection Instructions

Specimen Collection: Urine (Clean Catch Mid-Stream/CCMS or Straight Catheter)

  • Request a repeat specimen when there is no evidence of refrigeration for a sterile cup collection and the specimen is greater than 2 hours old.
  • Foley catheter tips/bags
  • Catheter bags
  • Leaky containers
  • Non-sterile container (example: pill bottles or household containers)
