CONTAINER TYPE:

Scotch® Tape slide MUST be submitted in a sealed, covered container or a SWUBE® tube.

COLLECTION:

The specimen is best obtained a few hours after the patient has retired (i.e. 2200 or 2300), or the first thing in the morning before a bowel movement or bath. The collection procedure is essential if valid results are expected. Clear Scotch® Tape MUST be used. The non-transparent type is unsatisfactory. Specimen of choice is a SWUBE® tube.

SPECIMEN REQUIREMENTS:

Scotch® Tape slide preparation of perianal region, SWUBE®  tube

REJECTION CRITERIA: Use of non-transparent Scotch® Tape, Scotch® Tape on BOTH sides of the microscope slide, use of a frosted microscope slide, Scotch® Tape submitted sticky side up. Stool specimens are NOT satisfactory for pinworm examination.
MINIMUM VOLUME: One slide
HANDLING INSTRUCTIONS: Specimen should be transported as soon as possible. When transportation is delayed, leave at room temperature. NOTE: Pinworm eggs are very infectious.
REFERENCE RANGE: No pinworm (Enterobius vermicularis) eggs identified.
LIMITATIONS OF TEST: A single negative result does not rule out the possibility of parasitic infection.
METHODOLOGY: Microscopic examination of preparation.
ADDITIONAL INFORMATION: The most satisfactory means of diagnosing pinworm infection is by the recovery of eggs or female worms from the perianal region, as only 5-10% of infected persons have demonstrable eggs in the stool. Click here for more information about Enterobiasis.
