Report Time: Next Day Evening | Sample: Blood (Serum) | Days: Except Sunday
H. pylori IgA is a specialized blood test that checks for an active mucosal immune response in the stomach. Unlike the IgG antibody (which indicates a past or chronic infection) or the Stool Antigen (which detects live bacteria), the IgA antibody specifically indicates that the body's mucous membranes are currently fighting an invasion.
This test is particularly useful for distinguishing between a past, cured infection and an ongoing, active inflammation of the stomach lining (Gastritis).
IgA vs. IgG: What's the Difference?
Your immune system produces different soldiers (antibodies) at different stages of an infection:
-
✔IgA (The Frontline Defense): These are found in the mucous membranes of the stomach. High IgA levels typically suggest an Active or Recent Infection where the stomach lining is currently irritated. IgA levels drop relatively quickly after successful treatment.
-
✔IgG (The Memory): These are scar antibodies. Once you have had H. pylori, IgG can stay positive for years, even after you are cured. Therefore, IgG alone cannot tell if you are currently sick.
When is this Test Used?
Doctors order the IgA test in specific scenarios:
-
➤When Stool/Breath Tests are Difficult: Some patients (like young children or those on certain medications) cannot perform the breath test or provide a stool sample easily.
-
➤To Check for Acute Inflammation: Combined with IgG, it helps paint a fuller picture of the immune system's activity.
-
➤Monitoring Treatment (Sometimes): Since IgA levels fall faster than IgG after antibiotics, a significant drop in IgA can suggest the treatment is working (though Stool Antigen is still preferred for this).
Interpreting Your Results
| Result | Interpretation |
|---|---|
| Positive (High) | Indicates Active or Recent Infection. The immune system is currently reacting to H. pylori in the stomach lining. |
| Negative (Low) | No active mucosal response detected. |
| Borderline | Inconclusive. Repeat testing or correlation with clinical symptoms is advised. |
Frequently Asked Questions (FAQs)
No, fasting is not required for the H. pylori IgA blood test. You can eat and drink normally.
Antibiotics can reduce the bacterial load, which might lower antibody production over time, but blood antibodies (IgA) do not disappear immediately. However, for the most accurate diagnosis, consult your doctor about timing.
No, the H. pylori IgA test is processed on all days Except Sunday at Sanovra Lab.
