3 Day Parasitology

Product Details

The 3 Day Parasitology test can assist in identifying parasitic infection in a patient. Symptoms of parasitic infection include acute watery diarrhoea, nausea, abdominal pain and cramps, fatigue and weight loss. Testing over 3 consecutive days increases rates of parasitic detection by 95%. A 3 day parasitology can help to identify infection of parasites such as: Blastocystis hominis, Dientamoeba fragilis, Giardia lamblia, Endomilax nana and Entamoeba histolytica. All parasites that are detected during tested are reported in the patient’s lab results.

The parasites commonly detected include Blastocystis hominis, Dientamoeba fragilis, Giardia lamblia, Endomilax nana, Entamoeba histolytica and Cryptosporidium parvum. If any other parasites are detected, they will also be reported.

This test is specifically indicated for patients suspected of parasitic infection. A 3 day parasitology increases the likelihood of parasitic detection.

Patient Preparation:

  • Patients must follow their usual diet prior to collecting a stool specimen
  • The stool specimen must be collected in the morning, where possible or the first bowel motion of the day
  • If the patient is currently taking antibiotics, only proceed with this collection two weeks after the patient can completed the course of probiotic therapy
  • Natural laxatives can be used if constipation is a problem. This includes herbal and nutritional supplements. Do not use pharmaceutical laxatives as these medications can alter test results.

Turnaround Time:

The standard turnaround time for this test is 10-14 working days from the date the patient’s specimen/s are received at our laboratory.

Companion Tests:

  • Intestinal Permeability (IP)
  • Complete Digestive Stool Analysis (CDSA)
  • Secretory IgA (sIgA)

The 3 Day Parasitology may be further supported by additional BeFunctional tests. The most relevant test here is the Complete Digestive Stool Analysis (CDSA) which will provide a comprehensive assessment of the microbiology of the gut, including important biochemical markers, mycology (yeasts), parasitology, bacteriology and levels of beneficial bacteria. When a parasitic infection is present, it is often found that the levels of beneficial bacteria are significantly lowered, which may mean the parasite is using the bacteria as a nutrient source.

The Intestinal Permeability (IP) test may also be useful adjunct to the 3 Day Parasitology test. A "leaky gut" may be a predisposing factor to, or be caused by parasitic infection. Combining the 3 Day Parasitology with the CDSA and IP tests will provide a comprehensive overview of gut function and alert the practitioner to the additional need for gut repair.

Also worth considering as a companion test is the Secretory IgA (sIgA) which may be particularly indicated when the patient is fatigued and depleted as a result of parasitic infection. Secretory IgA levels in saliva are thought to be representative of the functional status of the entire mucosal system. Maintaining a high daily production of sIgA is essential for an adaptive immune response and may be significantly affected by the prolonged stress of parasitic infection on the body.
