A detailed analysis of all intestinal parasites from all seven continents (including protozoa, trematodes, tapeworms, and nematodes), Parasitology Center Inc.’s Comprehensive Stool Analysis provides a detailed summary of findings based on the collection of stool samples. Also included is an analysis of bio-indicators, such as red and white blood cells, mucus, fatty acid crystals, starch granules, undigested tissue, and beneficial bacteria.

To perform the test, carefully follow the detailed instructions for your Comprehensive Stool Analysis kit (link below). You’ll collect two samples of soft stool specimens passed two to three days apart, or when you are experiencing the most symptoms. If your symptoms are cyclical (sometimes they are worse and then better) it is more important to take your specimens when you are feeling worse than following the general 2-3 days apart guideline. You’ll then mail your samples to PCI’s lab, storing them in a cool space (refrigeration is not necessary) until dropping in your mailbox.

Common FAQ’s:

How do I know if I have a parasite?

It’s best to confirm the presence of a parasite through detailed stool testing. Parasites may cause the following symptoms, although these symptoms are nonspecific in nature and therefore not sufficient to make a diagnosis of parasitic infestation:

  • Abdominal pain
  • Diarrhea
  • Nausea or vomiting
  • Gas or bloating
  • Dysentery (loose stools containing blood and mucus)
  • Rash or itching around the rectum or genitals
  • Stomach pain or tenderness
  • Fatigue


What causes parasites:

Parasites may be caused by the following factors:

  • Contaminated drinking water
  • Skin contact with contaminated water
  • Contaminated food
  • Insects
  • People and pets
  • Soil containing parasite larvae


I thought parasites were more common in developing countries. Can I get a parasitic infection in the US?

Yes, because of modern trade, foreign travel, poor farming practices and other reasons, those residing in the US are still at risk of parasitic infections.

I’m concerned about my pet having parasites. Can I test them, as well?

Yes! You can use the same tests for your pets as you do for humans.

How long does it take to receive the results?

Your results will be available approximately 2 weeks after sending in the test.
