Pinworm slide

This test detects a parasite called Enterobius vermicularis (pinworm) by collecting the worm or its eggs in stool or directly from the anus (rear end). This test is used to help diagnose suspected enterobiasis, which is an infection with this parasite.

Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:
