If a worm is visible in the patient sample, submit worm in alcohol in a leak-proof container for test code 3950 Parasite Identification, Worm. Do NOT order an O&P exam or submit in Total-Fix or other stool preservative.
The pinworm exam (test code 4496) is the recommended test for detection of Enterobius vermicularis (pinworm). A special collection device called a pinworm paddle can be obtained from Client Supplies and is used to collect perianal material. Alternatively, clear cellulose tape applied to a clear glass slide can be submitted. E vermicularis most often infects children and is associated with perineal pruritus.
