GI-MAP: Your Complete Gut Health Map
Your guide to GI-MAP: what molecular qPCR testing measures, how results are interpreted and when it may be useful. Home collection is available across Saudi Arabia.
GI-MAP Testing: What Does It Measure and How Are Results Interpreted?
GI-MAP stands for Gastrointestinal Microbial Assay Plus, an advanced molecular test that uses quantitative PCR (qPCR) to analyse the DNA of microorganisms in the digestive tract.
Using a single stool sample, this test assesses a range of markers beyond those included in standard stool tests, helping your doctor build a broader picture of gut and microbiome health.
💡 GI-MAP Detects and quantifies selected microorganisms rather than reporting only a positive or negative finding.
Molecular PCR technology measures microbial DNA and can detect organisms that routine culture may miss.
Markers assessed by GI-MAP
GI-MAP assesses six main areas of digestive health.
Bacterial pathogens
Tests for disease-causing bacteria such as H. pylori , Salmonella, pathogenic E. coli and others
Parasites and fungi
Tests for intestinal parasites and fungi, including Candida.
Microbiome balance
Assesses selected beneficial and potentially harmful bacteria to help evaluate the intestinal environment.
Intestinal immunity
Assesses secretory IgA and inflammatory markers such as calprotectin and lactoferrin.
Digestion and absorption
Assesses markers related to digestive enzyme function and fat absorption.
Antibiotic resistance
Looks for selected antibiotic resistance genes to support medical treatment decisions.
What do GI-MAP results look like?
Markers are presented with reference ranges and flags such as normal, high or low, alongside clinical interpretation in Arabic.

GI-MAP FAQs
What is GI-MAP?
GI-MAP is a molecular stool test using quantitative PCR to assess selected microbial DNA and gut health markers, including bacteria, parasites, fungi and inflammation-related markers.
Is GI-MAP available in Saudi Arabia?
Yes. GI-MAP is available across Saudi Arabia through Trust Medical Labs. The service can be arranged remotely, with home delivery of the collection kit and return of the sample to the laboratory.
How long do GI-MAP results take?
Results usually take two to three weeks from sample receipt by the laboratory. You receive a digital report with a detailed Arabic explanation.
How does GI-MAP differ from a standard stool test?
Standard stool testing may use microscopy, culture or other methods to assess selected organisms. GI-MAP uses molecular PCR to quantify a broader panel of selected microbes and other gut health markers. If bloating after meals is your main symptom, your doctor may also consider a SIBO breath test.
