Oral Parasite Stool Microscopy (Microscopic Examination of Stool for Parasites)

Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, abdominal pain, unexplained weight loss, or if you’ve traveled to areas with higher parasite risks. It’s also used to check for parasites in people with weakened immune systems or those with chronic digestive problems.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to collect a fresh stool sample in a container provided. If you’re using a stool softener or laxative, let your provider know, as it could affect the sample.

During the Test

The collected stool sample is mixed with a special solution and examined under a microscope by a trained lab technician. They look for signs of parasites, their eggs, or other microscopic organisms that may indicate an infection.

What the Results Mean

Positive results indicate the presence of parasites or their eggs, which can confirm a parasitic infection. Negative results mean no parasites were found in the sample, but this doesn’t rule out infection if parasites were present earlier or in other parts of your digestive system.
