Helicobacter pylori IgA antibodies
Detects IgA antibodies to Helicobacter pylori — bacteria frequently causing chronic gastritis and peptic ulcer disease. IgA are mucosal immunoglobulins and may indicate active gastric mucosal inflammation.
Used for:
- initial examination of patients with stomach complaints;
- additional H. pylori diagnostics;
- in complex with other methods by physician prescription.
Note: antibody presence does not always confirm active infection as antibodies may persist. For accurate confirmation, physician may order breath test or H. pylori stool antigen.
Infection routes: contact-household (dishes, saliva); poor hygiene.
Recommended for:
- patients with gastritis symptoms;
- chronic gastritis/peptic ulcer patients;
- frequent NSAID users (by physician prescription).
Biomaterial: Venous blood
- Draw blood fasting (8-12 hours without food)
- Water is permitted
- Exclude fatty food and alcohol 24 hours before
- No smoking 30 minutes before
Medications: If taking antibiotics, bismuth preparations, proton pump inhibitors, hormonal drugs, or immunosuppressants — inform physician; dose adjustment usually not required unless directed by physician
- Epigastric pain and burning;
- heartburn, acid reflux;
- heaviness after eating, nausea;
- suspected gastritis/ulcer.
Note: Results evaluated by gastroenterologist together with symptoms.
Negative IgA — active process unlikely.
Positive IgA — possible active infection/inflammation.
At positive result: gastroenterologist consultation. Self-treatment not recommended.
