Definition

Stool ova and parasites exam is a lab test to look for parasites or eggs (ova) in a stool sample. The parasites are associated with intestinal infections.

How the Test is Performed

A stool sample is needed.

There are many ways to collect the sample. You can collect the sample:

  • On plastic wrap. Place the wrap loosely over the toilet bowl so that it is held in place by the toilet seat. Put the sample in a clean container given to you by your health care provider.
  • In a test kit that supplies a special toilet tissue. Put it in a clean container given to you by your provider.

Do not mix urine, water, or toilet tissue with the sample.

For children wearing diapers:

  • Line the diaper with plastic wrap.
  • Position the plastic wrap so that it will prevent urine and stool from mixing. This will provide a better sample.

Return the sample to your provider's office or lab as directed. At the lab, a small smear of stool is placed on a microscope slide and examined.
