Gastro Intestinal Testing

The Complete Digestive Stool Analysis (CDSA) is a functional test that provides an overview of the components of digestion, absorption, intestinal function and microbial flora, as well as identifying pathogenic bacteria, parasites and yeasts.
The CDSA is a non-invasive test providing invaluable information for the patient and practitioner in terms of understanding the role of poor digestive function in disease states.  Poor digestive function and imbalanced gut flora may play a crucial role in the underlying cause of a number of health conditions. Symptoms such as constipation, diarrhoea, flatulence, bloating, abdominal discomfort and bad breath are all indicative of poor gut function

CDSA Levels 1-5:

 

CDSA Tests

Bacteriology

Mycology
(Yeasts)

Parasitology

3 Day

Parasitology

 

Short Chain Fatty Acids

Biochemical Markers (Pancreatic Elastase, Valerate/ IsoButyrate)

Sensitivities (Bacteria/ Yeasts)

CDSA Level 1

 

 

 

 

CDSA Level 2

 

 

CDSA Level 3

 

CDSA Level 4

CDSA Level 5

 

 

Specimen Requirements

CDSA Levels 1-3 require one stool collection.
CDSA Level 4 and Level 5 require stool collections on three consecutive days.
The test kits provided contain everything required to complete this test.

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

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)
• Secretory IgA (slgA)
• IgG Food Sensitivity Profile

The Intestinal Permeability (IP) test may also be a useful adjunct to the CDSA. A “leaky gut” may contribute to or be caused by poor digestive function. These tests are commonly requested together. Combining the CDSA and the IP tests will provide a comprehensive overview of gut function and alert the practitioner to the additional need for gut repair.

The Secretory IgA (sIgA) saliva test is also recommended in conjunction with the CDSA as a deficiency of sIgA can increase gut permeability and patient susceptibility to food sensitivities and/or allergies and pathogenic invasion.

Food sensitivities will also contribute to poor digestion and gut inflammation. The IgG Food Sensitivity Profile is a blood test which screens for IgG antibodies to a panel of foods. This test is recommended with the CDSA when food sensitivity is suspected as an underlying cause of digestive dysfunction.
