Answer:
Is a tape that you place on your anus to see weather or not you have any parasitic. This should be done in the early morning. this is when the eggs (what you are trying to collect) will be.
HOW:
You lift one side of your buttock up (to show the anus) and you place a clear cellophane tape with the sticky side towards the client anus on the skin. then you remove it and put it on the slide.
Hope this helps...
