Collection Method

Clean Catch Midstream Specimen

1. Instruct the patient how to perform a midstream Clean Catch Urine Collection using the collection kit and “Patient Instructions for Clean Catch Urine” info sheet (Attachment I). These instructions shall also be posted in all outpatient laboratory bathrooms where patient urine collections take place.

2. Provide the patient with a take-home collection kit and hard-copy instructions if collecting outside the laboratory.

Straight Catheter

1. Collect per nursing protocol.

2. Mark sample as a straight catheter collection.

Foley Catheter

1. Collect per nursing protocol.

2. Mark specimen as a Foley/Indwelling catheter collection.

Pedi Bag (High Risk Collection)

1. Cleanse the urethral area with the castile soap pad from the BD vacuum tube urinalysis kit, or another appropriate sterilizing cleanser. Rinse the skin with a water-damp sterile pad, and dry thoroughly with a sterile pad.

2. Apply the Pedi-bag to the skin around the urethra in such a way that it will catch the urine during urination.

3. Open a sterile specimen cup or conical Falcon tube. Carefully remove the Pedi-bag from the patient, and straighten the Pedi-bag with your fingers. Pour the urine from the Pedi-bag into the sterile cup or Falcon tube. DO NOT SUBMIT THE PEDI BAG FOR TESTING.

4. If there is insufficient urine to fill BD Vacutainers to the minimum fill lines, pour the entire urine into a sterile transport tube or cup. Close lid TIGHTLY. A sterile syringe with a black transport cap is acceptable, but not preferred.

5. Mark sample as a Pedi-bag collection.

Syringe/Aspirate (High Risk Collection)

1. Syringes of urine may be acceptable in certain circumstances. Remove any sharps, and cap syringes appropriately for transport.

2. Mark sample with the collection method and specific source (i.e. left nephrostomy, right ureter, etc.)

3. HAND-DELIVER SYRINGES TO THE LABORATORY. NEVER TRANSPORT SYRINGES THROUGH THE PNEUMATIC TUBE SYSTEM.

Reflex Testing

Urine performed with a Urine with Microscopic If Indicated will reflex if positive for the following results:

  • RBC: ≥ small/1+ 
  • Leukocytes: ≥small/1+
  • Protein: ≥30 mg/dL/1+
  • Nitrite: Positive
  • Clarity: Turbid
