Specimen Collection Manual: Urine for Culture

Instructions

Collection Preparation

  1. A first morning specimen is optimal.
  2. The patient must wash his/her hands.
  3. Open the collection system and remove the blue-top sterile collection-transfer container and towelettes, as seen below.
    NOTE: The blue collection cup used ONLY for collection and transfer of the urine specimen. It should NOT be used to transport the specimen to the Laboratory as it may leak when in transit.
    SAFETY WARNING: Avoid contact with the recessed needle beneath the yellow sticker on the blue-cap.
  4. Prior to genital cleansing, unscrew the cap of the urine specimen container. Place cap on the counter with the attached blue aspiration nozzle facing upward. To avoid contamination, do not touch the inside of the cup, cap, or aspiration nozzle.

Specimen Collection Criteria

Clean Catch Instructions

  1. The patient should cleanse themself with the towelettes as follows:
    • Males:
      • Wipe the head of the penis in a single motion with the first towelette. Repeat with the second towelette. (Uncircumcised patients should hold the foreskin back before cleansing.)
      • Urinate a small amount into the toilet. This flushes most contaminants from the urethra.
      • After a single stream is achieved, pass the specimen cup into the stream and obtain urine sample.
    • Females:
      • Sit comfortably on the toilet and swing one knee to the side as far as possible.
      • With the forefingers of one hand, spread the outer folds of the labia and keep them apart during the rest of the collection procedure.
      • With the other hand, wipe the inner labial folds front to back in a single motion with the first towelette.
      • Wipe down through the center of the labial folds with the second towelette.
      • Keep the labia separated and urinate a small amount into the toilet. This flushes most contaminants from the urethra.
      • After a single stream is achieved, pass the specimen cup into the stream and obtain sample.
  2. The cup should be at least 1/4 to 1/2 full.
  3. To prevent contamination of specimen with skin flora, the patient should remove the cup before the flow of urine stops and before releasing the labia or penis.
  4. The patient should then completely empty their bladder of urine into the toilet.
  5. Wipe off the outside of the container after replacing the cap.
  6. The patient must wash their hands.
  7. Label the specimen and immediately proceed to the urine transfer steps listed below.

  2. Obtain a minimum of 10 mL of urine.
  3. Unscrew the blue cap of the sterile cup and place the cap on the counter with the attached blue aspiration nozzle facing upward. Do not touch the inside of the cup, the cap, or the straw.
