Test Description

Parasitology, Stool Exam (three specimens)

Parasites come in many shapes and forms. They may be found on the skin, in the hair, in the muscles, blood, liver, lungs, bladder, and in the intestinal tract. In some third world countries, it is a leading cause of sickness and death. In the U.S., there is a misconception that intestinal parasites are rare and therefore, parasitology tests are usually not ordered. Most intestinal infections come from contaminated food and water. In many immunocompromised patients, parasites are very common.

The specimen should be collected in special containers supplied and three specimens submitted. Most positive results are obtained from diarrhea specimens before any antidiarrheal or antiparasitic therapy. The specimens are examined for ova and parasites as well as IFA tests for Cryptosporidium and Giardia lamblia.

Ova and parasites are detected using iodine/saline and trichrome staining. The principle for Cryptosporidium and Giardia is antigen staining with specific antibodies and IFA.

Collect three separate stool specimens, placing each in its own plastic transport tube, with time & date noted on the vial. Collection days should be spread out to approximately every other day.

Profile Includes Stool exam (single specimen); Cryptosporidium Ag; Giardia Ag
