| ==Overview==
| |
| Diagnosis is often made clinically by observing the female worm (or many worms) in the peri-anal region, but can also be made using the [["scotch-tape" test]], in which the sticky side of a strip of [[cellophane]] tape is pressed against the peri-anal skin, then examined under a microscope for pinworm eggs.

| ===Scotch-tape Test===
| |
| Sticky side of a strip of [[cellophane]] tape is pressed against the peri-anal skin, then examined under a microscope for pinworm eggs. The actual worms may be seen in the host's feces; however the eggs are invisible to the naked eye. The diagnostic characteristics of egg are: size 50-60 µm by 20-32 µm; typical elongated shape, with one convex side and one flattened side and colorless shell.<ref>{{cite web | url = http://pathmicro.med.sc.edu/parasitology/nematodes.htm| title =PARASITOLOGY - CHAPTER FOUR NEMATODES (Round Worms) | accessdate = 2007-10-18| publisher = The Board of Trustees of the University of South Carolina}}</ref> On [[histology|histologic]] cross-section, alae or wings (running the length of the worm) are identifying features of the pinworm (see micrograph).<ref>Diagnostic Findings Enterobiasis.
