  Method and collection

  Method

  Real-Time Polymerase Chain Reaction

  Preparation

  Patient should not use antacids, barium, bismuth, antibiotics, anti-malarial agents, antidiarrheal medication or oily laxatives prior to specimen collection. After administration of any of these compounds, specimen collection should be delayed for 5 to 10 days or at least two weeks after barium or antibiotics.

  Collection

  Avoid contamination of stool specimen with urine or water. Specimens are best collected in a bedpan or a clean dry container. A suitable area (i.e., bloody, slimy, watery) from the sides, ends and middle of the stool should be selected using the collection spoon provided. Fill with sufficient stool to bring the liquid level up to the "Fill" line. This will result in approximately 5 mL of sample. Stir each specimen with the spoon provided, tighten the cap and shake firmly until the specimen is adequately mixed. When mixing is complete, the specimen should appear uniform. Complete the label on the vial and place the vial in the plastic bag. Transport the specimen to the laboratory.
