Special Info
Test includes microscopic examination for pinworm only. Specimen collection at improper times may reduce recovery. The sample should be obtained immediately upon arising in the morning prior to bathing or bowel movement. Hold the Swube paddle by the cap and remove it from the tube. Using gentle pressure, press the sticky side of the Swube paddle against the skin around the rectum 3-4 times. Return the Swube paddle to the tube; tighten lid. Transport to Microbiology at room temperature. Any specimens submitted using frosted tape will be rejected.
Clinical Info
Pinworm infection is caused by Enterobius vermicularis, a parasite commonly found in the environment. Transmission is generally via the fecal to oral route. Adult worms live in the intestine but migrate to the perianal area during the night to deposit their eggs causing a local pruritus. Rarely the organisms can cause vulvovaginitis and urinary tract infections. One negative result does not rule out the possibility of parasitic infection.
