Cellulose Tape or Swube Tube Procedure for Demonstration of Pinworm Eggs
The most reliable and widely used technique for demonstrating pinworm eggs (Enterobius vermicularis) is the cellulose tape or swube tube procedure. The adhesive part of the swube tube or tape is applied to the perianal area first thing in the morning. Specimens should be collected on three consecutive mornings prior to bathing. If an infection is present, eggs and sometimes adult worms of Enterobius vermicularis will be present on the tape and can be seen under the microscope.
