• Digestive discomfort: bloating, gas, abdominal pain or irregular bowel habits.
• Chronic or acute diarrhoea: loose stools, urgency or diarrhoea following illness or travel.
• IBS or IBD: ongoing digestive symptoms where microbiome patterns may be relevant.
• Food sensitivities: digestive or systemic reactions suspected to relate to microbial imbalance.
• Unexplained fatigue: tiredness potentially linked with gut-related factors under review.
• Joint discomfort: intermittent stiffness or pain sometimes observed alongside gut symptoms.
• Recurrent infections: individuals with frequent immune challenges where gut health is being explored.
• Nutritional deficiencies: suboptimal nutrient status possibly associated with malabsorption patterns.
• Mucosal barrier concerns: practitioners assessing potential disruption of gut lining integrity.
• Fever, nausea or vomiting of unclear origin: when gastrointestinal pathogens are a consideration.

The GI360 Essentials (1-day) test combines multiplex PCR, culture, MALDI-TOF identification, microscopy and biochemical assays to evaluate a single stool sample for pathogenic organisms, parasites, viral targets and core microbiome indicators. The profile includes analysis of microbial abundance and diversity across key bacterial phyla.

This assessment may be clinically useful when exploring persistent digestive concerns, suspected infections, microbiome imbalance or digestive symptoms that appear to relate to microbial factors. Although a single-day sample provides a snapshot rather than a multi-day view, it still offers detailed insight into microbial composition, dysbiosis patterns and potential pathogenic organisms.

Practitioners typically interpret GI360 Essentials findings alongside clinical history, diet, symptom patterns and lifestyle influences. When used in this way, the test can support discussions about gut ecology, digestive function, potential triggers and practical next steps.

Practical

Specimen requirements:

Stool

1 day collection 

No Call / Inhibited
In certain circumstances, stool samples may not yield results for a limited section of viruses, pathogenic bacteria and parasites [known as : No Call / Inhibited]. Statistically this can affect approximately 6% of tests.
Many factors contribute to this issue including diet, medication, supplements, and competing DNA. Excessive calcium, tannic acid, bile salts, haemoglobin, melanin, collagen, urea, degradation products, complex polysaccharides and polyphenolic substances have also been found to cause inhibition.Test reports affected are not considered to be defective and thus are not eligible for cancellation or refunds.
Resubmission of the a supplementary sample to attempt analysis can be accommodated with billable costs limited to supply and return shipping.
By ordering this test, you accept the conditions and risks explained here.

Also available as 2 and 3 day collection.

Average processing time:

21 days

Available add-ons:

Zonulin

Age Considerations:

The PCR Microbiome section (only) may best be served for those ages 2 and above due to variations in the microbiome in ages 0-2.
