A fresh stool specimen is used for microscopic examination.
Normally, no ova or parasites are seen. When seen, they can often be visually identified.
Stool passed into a toilet bowl is not ideal for culture as it may contain contamination from others. It is better to pass the stool directly into a collection jar, or a bedpan. A sample of the stool can be separated with a tongue blade and placed into a specimen container for deliver to the lab.

Stool for O&P
None seen
