Instructions
Collection Instructions: The patient should not use powders or creams during the collection period. If the patient washes or uses the bathroom before the specimen is collected, it will decrease the chances of finding pinworm eggs. ?A series of three specimen collections are recommended.??The best time to collect a specimen is first thing in the morning, before the patient gets out of bed. Inside each collection tube is a paddle with a sticky side. Wearing gloves, press the sticky side of the paddle against the anal opening. Put the paddle inside the collection tube, remove gloves, and thoroughly wash your hands. Repeat this process each morning using one Pinworm paddle per morning.

Limitations
If a Pinworm infection is suspected, a Pinworm test is recommended, rather than an Ova & Parasite test. Only 5 – 10% of people infected with pinworm have the worm or its eggs in their stool and seeing these on an Ova & Parasite test is incidental.
Reference Range
Negative
Clinical Significance
Pinworm is one of the most common intestinal parasitic infections in children causing rectal itching, abdominal cramps and diarrhea.
