H. pylori IgG
An H. pylori IgG test detects IgG antibodies against Helicobacter pylori, a bacterium that can infect the stomach lining. A positive result may indicate a current or past H. pylori infection, as IgG antibodies can persist even after successful treatment.
What It Measures
This test detects the presence of IgG antibodies directed against Helicobacter pylori in your blood. H. pylori is a common bacterium that infects the stomach lining and can cause gastritis, peptic ulcers, and is associated with an increased risk of gastric cancer. The test provides a qualitative result indicating whether antibodies are present.
Why It Matters
H. pylori infection is one of the most common bacterial infections worldwide and can lead to chronic gastritis and peptic ulcers if untreated. Long-standing infection may also be associated with an increased risk of gastric cancer. Identifying the infection allows healthcare professionals to recommend appropriate treatment, typically a combination of antibiotics and acid-suppressing medication.
When to Test
Testing may be recommended if you experience persistent digestive symptoms such as upper abdominal pain, bloating, nausea, or unexplained weight loss. It may also be relevant if you have a family history of gastric cancer or peptic ulcer disease. Consult a healthcare professional for guidance.
Lifestyle Tips
Maintain good hand hygiene and food safety practices. Eat a balanced diet rich in fruits, vegetables, and whole grains. Limit consumption of processed foods, excessive salt, and alcohol. If you are diagnosed with H. pylori, complete the full course of prescribed treatment. Manage stress and avoid smoking, as these factors can aggravate gastric symptoms.
Frequently Asked Questions
Can H. pylori IgG antibodies remain positive after treatment?
Yes, H. pylori IgG antibodies may remain detectable for months or even years after successful eradication of the bacterium. Therefore, a positive IgG result does not necessarily indicate an active infection. Your healthcare professional may recommend other tests, such as a breath test or stool antigen test, to confirm active infection or successful treatment.
How common is H. pylori infection?
H. pylori infects a significant proportion of the global population, with higher prevalence in developing countries. Many infected individuals remain asymptomatic throughout their lives. If symptoms develop, effective treatment is available. Consult a healthcare professional for personalised assessment and guidance.
