Helicobacter Pylori Stool Antigen
HPSA
Description
"Helicobacter Pylori Stool Antigen" test detects H. pylori in your digestive tract by analyzing a stool sample. Doctors often order it when symptoms like stomach pain, bloating, or indigestion suggest infection. A positive result confirms active H. pylori, which may increase ulcer or stomach cancer risk. This test also helps monitor treatment success after antibiotics. It’s non-invasive, accurate, and supports early detection. Results guide care plans that may include acid reducers, antibiotics, or follow-up testing.

Test Group Description
Microbial Assessment Group: Tests in this group analyze microbial presence and activity in various samples, offering insights into microbial populations and their impact on health. They help identify specific microorganisms, assess microbial diversity, and evaluate microbial functions in different environments. Infection Group: Tests within this group detect markers indicative of various infections, aiding in the diagnosis and management of infectious diseases.
Optimal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Normal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Autoimmune gastritis (Immune-mediated inflammation of the stomach lining)
Functional dyspepsia (Chronic indigestion without apparent cause)
Gastritis (Inflammation of the stomach lining)
Gastroesophageal reflux disease (Chronic acid reflux)
Gastrointestinal bleeding
Helicobacter pylori infection (Bacterial infection of the stomach)
Iron deficiency anemia (Anemia due to insufficient iron levels)
Mucosa-associated lymphoid tissue lymphoma (Rare lymphoma originating from mucosal tissue)
Peptic ulcers (Open sores in the lining of the stomach or duodenum)
Key Reasons For Testing
H. Pylori Diagnosis: Stool antigen testing detects H. pylori antigens in stool, offering a non-invasive diagnostic method.
Treatment Monitoring: Confirms eradication success post-therapy by showing the absence of H. pylori antigens.
Follow-Up Testing: Monitors recurrence or reinfection after treatment using stool antigen detection.
Non-invasive Option: Provides a safer alternative to endoscopy for diagnosing H. pylori infection.
Cancer Risk Screening: Identifies H. pylori infection, a key risk factor for gastric cancer.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
