Helicobacter Test (13c-Urea)

Helicobacter Test is employed as a non‑invasive diagnostic tool for detecting active Helicobacter pylori infection.

• Screening of adults presenting with dyspeptic or upper‑GI symptoms to identify active H. pylori infection.
• Confirmation of bacterial eradication after a prescribed course of antibiotics, typically performed 4‑6 weeks post‑treatment.
• Evaluation of population prevalence in epidemiological surveys, providing a reliable, non‑invasive measure of infection rates.
• Assessment of H. pylori status before endoscopic procedures or gastric surgery to guide peri‑operative management.
• Use in cases where serologic testing is ambiguous or where patients have received recent antibiotics or proton‑pump inhibitors.

Helicobacter Test is generally well tolerated, but as with any diagnostic agent, some individuals may experience mild or, rarely, more serious reactions. These events are usually self‑limiting and do not require specific treatment.

Common

• Mild nausea or stomach upset after ingesting the urea solution.
• Temporary abdominal bloating or mild cramping.
• Brief metallic or unusual taste sensation during the test.
• Light‑headedness or mild headache that resolves quickly.
• Mild transient dizziness or feeling of warmth.

Serious

• Allergic reaction such as rash, itching, swelling of the face or throat.
• Severe vomiting or persistent gastrointestinal distress.
• Anaphylactic shock, though extremely rare, requiring immediate medical attention.
• Severe abdominal pain with signs of intestinal obstruction (very rare).

When using Helicobacter Test, certain precautions should be observed to ensure accurate results and patient safety.

• Patients should fast for at least one hour before ingesting the 13C‑Urea solution to avoid dilution of the breath sample.
• Recent use of antibiotics, bismuth compounds, or proton‑pump inhibitors may suppress bacterial urease activity and lead to false‑negative results; a washout period is recommended.
• Individuals with known hypersensitivity to urea or related compounds should avoid the test.
• Pregnant or lactating women should discuss the test with their healthcare provider, as safety data are limited.
• Children under the age of six may require alternative diagnostic methods due to limited data on test performance.

Helicobacter Test may interact with certain medications or substances that affect gastric environment or urease activity, potentially altering test accuracy.

Avoid

• Antibiotics (e.g., clarithromycin, amoxicillin, metronidazole) taken within the previous 2‑4 weeks.
• Bismuth‑containing compounds used within the past 2 weeks.
• Proton‑pump inhibitors (omeprazole, esomeprazole, lansoprazole) taken within the previous 2 weeks.

Use with caution

• H2‑receptor antagonists (cimetidine, ranitidine) – may require a longer washout period.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – can cause gastric irritation that may affect results.
• Herbal supplements that influence gastric acidity (e.g., antacids, ginger) – advise temporary discontinuation.
• Alcohol consumption on the day of testing – may affect breath sample composition.
