Specimen:  1 ml serum from a SST tube plus 24-hour urine specimen.  Refrigerate urine specimen during collection, no preservative.
Comment:
  1. A single 24-hour urine collection may be used for Creatinine Clearance and Urea Nitrogen
    Clearance and Total Protein.
  2. Outpatients and Inpatients, Mercy Laboratory will order the appropriate serum BUN (BUNM) if a serum BUN has not been completed within 48 hours.  This will be done at no additional charge.  The patient needs to have blood drawn when the container is picked up or delivered.  In order to avoid possible duplication, the serum BUN is not to be ordered by the physician office, the hospital floor or admitting.
  3. Regional Lab Clients send 0.5ml serum for the BUN at the same time that the urine specimen is sent.  This enables analysis of both specimens by the same method for accuracy.  Mercy Laboratory will order the serum BUN at no charge.  Do not order a single BUN on the requisition.
Processing:  Aliquot 20 ml urine and indicate total 24 hour volume.  Send refrigerated.
Performed: Within 8 hours of receipt.

Order:

Specify collection type when ordering.

Specimen:

Midstream, catheterized, suprapubic, or nephrostomy.
0.5 ML urine minimum.
FOLEY CATHETER TIPS WILL NOT BE CULTURED.

Midstream:
Instruct patient of the proper collection technique. Collect in a sterile plastic container with a tight fitting lid. Provide the patient with 3 antiseptic towelettes. Use the following collection procedure:

  • The patient should thoroughly wash their hands.
  • Remove the lid from the container.Do not touch the inside surfaces.
  • Remove all clothing from the waist down.
  • Assume the appropriate position:
    Female-Sit on the toilet with legs spread apart.
    Male-Stand facing the toilet, or sit on the toilet with legs spread apart.
  • Open the towelettes and cleanse perineal area.
    Female: Separate the labia with the thumb and forefinger. Using downward strokes,cleanse one labium with a towelette and discard. Cleanse the other labium and meatu sin the same fashion, using a separate towelette for each stroke, and discard. Keep the labia separated.
    Male: If uncircumcised, retract the foreskin before proceeding. Cleanse the head of the penis with a towelette, using a circular motion from the urethral opening to the outer diameter of the penis. Discard towelette. Repeat using all the towelettes.
  • Hold container by the outside surface. Begin urinating into the toilet.
  • Place container under the stream of urine after a good flow has started.
  • Fill container half full and void remainder of the urine into the toilet.
  • Screw on the sterile cover.Do not touch the inner surface.

In-dwelling catheter:
Obtain the specimen with a needle and syringe. Select a puncture site 1-2 inches distal to the meatus. Clean the area to be punctured with 70% alcohol. Aspirate 10 ml of urine with a sterile needle and syringe.
NOTE: Specimens obtained from the collection bag are NOT clinically useful. FOLEY TIPS WILL NOT BE ACCEPTED.

Comments:

  • Results will be quantitated in colony forming units/ml.
  • Specimens containing more than 3 organisms will NOT routinely have organism identifications or susceptibility testing reported.This is generally indicative of an improperly collected specimen.A repeat specimen at an additional charge will be requested.
  • Foley catheter tips will NOT be cultured.
  • Urine culture transport tubes are not acceptable for a urinalysis.
  • Susceptibility testing will be routinely performed on all significant isolates.

RL Client Comments:

ALL OUTSIDE CLIENTS (INCLUDING NURSING HOMES)

  • If specimen is a Suprapubic or Nephrostomy specimen, write this on the SOURCE line
  • Refrigerate urine immediately after collection and during transport.
  • Deliver to Mercy Lab within 1 hour of collection. (DO NOT LEAVE URINE AT ROOM TEMPERATURE AFTER COLLECTION).
  • If delivery will exceed 1 hour from collect time:  Specimen must be transferred to a urine transport tube. (Available from the Mercy Lab.):

        Fill the urine transport tube with the urine specimen (approximately 4 ml).
        .  If there is <4 ml of urine, remove the rubber stopper from the tube and fill it to the minimum mark with
           urine.
        .  If the specimen was collected from an in-dwelling catheter using a syringe, inject the needle through
           rubber stopper and allow the vacuum inside of the tube to draw the correct volume into the tube.
        .  Transport at room temperature.  Specimen must be received by Microbiology Lab with 48 hours of
           collection.
