Aspergillus-specific IgG Test
The Aspergillus IgG test measures IgG antibodies against Aspergillus species, a type of fungus. Unlike IgE, which indicates allergic reactions, IgG reflects chronic or past exposure to Aspergillus.
🧬 Why the Test Is Done
Doctors order Aspergillus IgG to:
Diagnose Chronic Pulmonary Aspergillosis (CPA)
Detect aspergilloma (fungal ball in lungs)
Monitor treatment response in chronic Aspergillus infections
Investigate long-term respiratory symptoms like cough, hemoptysis, or fatigue
📊 Interpretation of Results
Result | Meaning |
|---|---|
Negative / Low | No significant past exposure or chronic infection |
Elevated IgG against Aspergillus | Suggests chronic or past infection, or ongoing colonization in lungs |
Interpretation should be combined with:
Symptoms (cough, shortness of breath, hemoptysis)
Imaging (chest X-ray, CT scan)
Other lab markers (Aspergillus IgE, total IgE, eosinophil count)
🩺 Symptoms of Chronic Aspergillus Infection
Persistent cough
Coughing up blood (hemoptysis)
Fatigue and weakness
Weight loss
Shortness of breath
Recurrent lung infiltrates or cavities on imaging
