Helicobacter Pylori Antigen Detection

This test measures the presence of Helicobacter pylori antigens in your stool. Helicobacter pylori is a type of bacteria that infects the stomach lining, leading to conditions like gastritis and ulcers. Detecting these antigens helps diagnose and monitor Helicobacter pylori infection.

• To diagnose Helicobacter pylori infection in individuals with symptoms like chronic stomach pain, bloating, nausea, or loss of appetite.
• To monitor the effectiveness of treatment for Helicobacter pylori infection.
• To identify carriers of the infection who may be at risk for complications such as stomach ulcers or gastric cancer.

This test is recommended if you:

• Have symptoms suggestive of Helicobacter pylori infection, such as recurrent stomach pain, discomfort, or indigestion.
• Have a history of peptic ulcers or gastritis.
• Need to monitor the effectiveness of treatment for a known Helicobacter pylori infection.

• Normal results indicate the absence of Helicobacter pylori antigens in your stool.
• Abnormal results suggest the presence of Helicobacter pylori infection.
• It is important to discuss your test results with your doctor, who will interpret them based on your clinical history and other diagnostic tests.

During this test:

• You will be asked to provide a 5gm stool sample in a sterile container.
• The sample should be refrigerated and delivered to the laboratory for testing.
• The laboratory will use the CLIA method to detect Helicobacter pylori antigens in your stool sample.

Before the test:

• Do not take antibiotics or bismuth preparations for 2 weeks before the test.
• Inform your doctor about any medications you are taking, as some may interfere with the test results.
• Follow any dietary restrictions or fasting instructions given by your healthcare provider.

Other tests that may be ordered alongside Helicobacter Pylori Antigen detection by CLIA (Stool) include:

• Urea breath test: This test detects the presence of Helicobacter pylori bacteria in your breath after consuming a specialised solution.
• Endoscopy: A procedure that allows direct visualisation and collection of tissue samples from the stomach for further testing.

This test is also known as the Helicobacter pylori stool antigen test or the H. pylori antigen detection test.

Helicobacter pylori infection is a bacterial infection that affects the stomach lining. It can lead to conditions such as gastritis, stomach ulcers, and even gastric cancer. Prompt diagnosis and treatment are important to manage this infection and prevent complications.
