3 Day Parasitology (3DP)

This test is designed to help identify parasitic infection in the human gastrointestinal tract. Symptoms of parasitic infection include acute watery diarrhoea, nausea, abdominal pain and cramps, fatigue and weight loss.
Recent reports indicate that the examination of more than one stool specimen is necessary to detect parasites in symptomatic patients. The literature clearly states that the most appropriate test for diagnosis and treatment of parasites requires the examination of three stool specimens, collected over consecutive days.
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.

Specimen Requirements

This test requires the collection of a stool specimen on three consecutive days. The test kit provided contains everything required to complete this test.

Patient Preparation

• Patients must follow their usual diet prior to collecting the stool specimen
• The stool specimen collected, should be the from the first bowel movement of the day. Care taken to ensure it is not contaminated with urine

Children

This test is suitable for children over the age of 4.

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

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

The results of the 3 Day Parasitology may be further supported by additional Clinical Labs Functional Pathology 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 information on 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 a 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 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.
