H. Pylori Antigen
Rapid Test (Feces)
Gold-standard non-invasive rapid chromatographic immunoassay for the direct qualitative detection of active Helicobacter pylori antigens in human stool specimens. Essential for initial gastric ulcer diagnosis and definitive post-treatment eradication confirmation in 10 minutes.
Why Stool Antigen Testing is the Non-Invasive Gold Standard
Helicobacter pylori colonizes the gastric epithelial lining, inducing chronic gastritis, peptic ulcer disease, and increasing gastric adenocarcinoma risk. Direct stool antigen detection provides active infection confirmation without invasive endoscopy.
Active vs. Historical Infection
Unlike serological antibody tests that remain positive for years following bacterial eradication, the QuRapid fecal antigen assay identifies only shedding, viable bacteria.
- Eliminates false-positive past exposure readings
- Recommended by Maastricht VI Consensus
- Accurate test of cure 4–6 weeks post-therapy
Non-Invasive Patient Comfort
Avoids invasive gastroscopy, anesthesia risks, and expensive hospital endoscopy suites for routine dyspepsia workup and pediatric screening.
- Screw-cap sampling stick minimizes stool handling
- Homogenized pre-filled buffer extraction
- Zero dietary restrictions or fasting required
Rapid 10-Minute Triage
Allows outpatient clinics and gastroenterology practices across the UAE to initiate first-line triple or quadruple eradication therapy on the same day.
- Immediate visual results in 10 minutes
- Reduces empirical PPI over-prescription
- Same-day dispatch across Dubai & Abu Dhabi

4-Step Rapid Diagnostic Protocol
Perform rapid fecal antigen testing with pre-dispensed extraction buffer tubes. No specialized laboratory centrifuge or equipment required.
Stool Sampling
Unscrew the collection tube cap. Insert the grooved applicator stick into the fecal specimen at 3 different sites to collect ~50 mg of feces (1/4 pea size). For watery diarrhea, aspirate 50 µL.
Buffer Mixing
Re-insert the applicator stick into the collection tube containing extraction buffer. Tighten cap firmly and shake vigorously for 15 seconds to ensure complete fecal dissolution.
Cassette Loading
Break off the dropper tip of the collection tube. Invert vertically and dispense exactly 2 drops (approx. 80 µL) of the sample extract into the sample well (S) of the test cassette.
10-Min Readout
Start timer. Read visual results at 10 minutes. Do not interpret after 15 minutes as late chromatographic background clearing may affect faint line verification.
Clear Colorimetric Result Windows
Visual interpretation criteria for point-of-care clinicians and laboratory personnel.
Diagnostic Result Interpretation
Evaluate lines appearing in the Control (C) and Test (T) regions.
Recommended Clinical Pathways

Contact Clinical SpecialistWhy is Stool Antigen preferred over Blood Antibody testing?
Antibody tests detect past exposure and remain positive for months or years after eradication. Stool antigen directly detects living, shedding bacteria, making it the non-invasive gold standard for active infection and post-treatment verification.
Should patients discontinue PPIs before testing?
Yes. Proton pump inhibitors (PPIs) and antibiotics should ideally be discontinued 2 weeks and 4 weeks prior to testing, respectively, to prevent false-negative results from bacterial suppression.
Does dietary intake affect the test results?
No. The monoclonal antibody immunoassay is completely unaffected by food, beverages, dietary fibers, or alcohol intake.
What is the turnaround time and reading window for the test?
Clear visual bands appear within 10 minutes. Results should not be interpreted beyond 15 minutes to prevent chromatographic background interference.
How can UAE medical centers procure this test?
