The Parasitology Stool Test Add-On - Genova Test Kit is an add-on to the GI Effects® Fundamentals profiles. This test includes a macroscopic and microscopic O & P stool test, and a PCR analysis to detect specific organisms.


Test Code:






Ship test kits to the lab Monday-Thursday only. No fasting is required for collection. However, before collecting a sample for fat absorption assessment, patients should consume their normal dietary fat intake. It is recommended to wait at least two weeks after completing medications such as PPIs, bismuth, antifungals, antibiotics, probiotics, and anti-parasitics. Patients should avoid taking digestive enzymes, laxatives (particularly mineral or castor oil), antacids, aspirin, and substances containing barium or bismuth for at least 48 hours before and during specimen collection. Consult with your physician before stopping any medications.

Test Results:

14 business days once the lab receives the specimen. May take longer based on weather, holiday, or lab delays.

What is the purpose of this test?

The Parasitology Stool Add-On - Genova Test Kit is a diagnostic test that examines microscopic fecal specimens for O&P and detects common protozoan parasites using PCR. This test can only be added to the GI Effects® Fundamentals Profile (GD2209) to provide a comprehensive analysis of gastrointestinal health.


What is included in the Parasitology Stool Test Add-On - Genova Test Kit?

The Parasitology Stool Add-On - Genova Test Kit is a comprehensive stool test that can be added to the GI Effects Fundamentals profiles to detect various types of intestinal parasites, including single-celled organisms (protozoa), which may cause gastrointestinal infections. 

This combination test includes the following assessments:

  • A macroscopic assessment and microscopic ova and parasite (O & P) stool test 
  • PCR analysis to assess for the presence of specific organisms, such as:
    • Entamoeba histolytica
    • Blastocystis spp.
    • Dientamoeba fragilis
    • Cyclospora cayetanensis
    • Giardia
    • Cryptosporidium parvum/hominis

The microscopic O & P test is the gold standard for parasite assessment. This test involves examining a stool sample under a microscope to identify the presence of parasite eggs (ova) or the parasites themselves. PCR analysis of stool for parasite testing offers greater sensitivity and specificity than microscopic tests alone. This advanced technique enables early diagnosis and precise identification of parasites, facilitating appropriate treatment strategies for patients.

The combination of microscopic and PCR analysis for parasites increases the diagnostic accuracy of parasitic infections. The Parasitology Stool Add-On - Genova Test Kit aims to detect various types of intestinal parasites, reducing the risk of missed infections and aiding in appropriate treatment and management strategies.


Who can benefit from a Parasitology Stool Test Add-On - Genova Test Kit?

This add-on test may be beneficial for the following groups of people:

  • Travelers to regions with poor sanitation or known endemic areas for parasitic infections.
  • Individuals experiencing persistent gastrointestinal symptoms such as diarrhea, abdominal pain, nausea, or vomiting.
  • People with a history of exposure to contaminated food, water, or soil.
  • Patients with compromised immune systems, including those with HIV/AIDS or undergoing immunosuppressive therapy.
  • Individuals with unexplained weight loss or nutritional deficiencies.
  • Healthcare workers or individuals in close contact with animals.
  • Those with a history of consuming raw or undercooked meats, fish, or shellfish.
  • Residents of or visitors to institutions such as nursing homes, daycare centers, or correctional facilities where outbreaks of parasitic infections are more common.
  • Individuals with a history of parasitic infections or a family history of parasitic diseases.
  • People with symptoms suggestive of specific parasitic infections, such as itching around the anus (suggestive of pinworm infection) or persistent skin rashes (suggestive of certain protozoan infections).


When should I order a Parasitology Stool Test Add-On - Genova Test Kit?

Individuals may order this add-on test kit if they have experienced symptoms related to an undiagnosed parasitic infection, including:

  • Abdominal pain or discomfort
  • Diarrhea
  • Constipation
  • Nausea and vomiting
  • Unexplained weight loss
  • Fatigue or weakness
  • Visible worms or eggs in stool
  • Itching or irritation around the anus or genital area
  • Disturbed sleep due to itching (especially in cases of pinworms)
  • Anemia (due to blood loss in cases of hookworm infection)
  • Allergic reactions (such as skin rashes or respiratory symptoms) in response to certain parasites
  • Digestive disturbances, including bloating and flatulence
  • Appetite changes, either increased or decreased
  • Fever or flu-like symptoms in severe cases of infection

It's important to note that symptoms can vary depending on the parasite type and the infection's severity. Additionally, some individuals may be asymptomatic carriers of certain parasites.
