Aspergillus Antibody IgG Serum Test
Short Name: Aspergillus IgG Serum Test
Also known as: Aspergillus IgG Antibody Test, Aspergillus Serology Test, Anti-Aspergillus IgG Test
Aspergillus Antibody IgG Serum Test test available at DNA Labs India for ₹1,989. Uses Enzyme Immunoassay on Serum samples. Results in Same-day reports available if sample collected on Mon/Wed/Fri by 9 am.. Free home collection in 300+ cities across India.
Overview
The primary purpose of the Aspergillus Antibody IgG Serum Test is to detect the presence of IgG antibodies against Aspergillus species in the bloodstream. This helps in diagnosing Aspergillus-related conditions, including allergic bronchopulmonary aspergillosis (ABPA), aspergilloma, and invasive aspergillosis, especially in immunocompromised individuals. It aids in monitoring treatment response and assessing exposure history.

How to Prepare
- Sample type: 2 mL serum from SST tube
- Ship refrigerated or frozen for stability
- Label the sample correctly with patient details
Doctor's Notes
"The Aspergillus Antibody IgG test is crucial for diagnosing fungal sensitization in patients with respiratory symptoms. Positive results indicate exposure, but clinical correlation is essential to distinguish infection from allergy."
Test Parameters & Specifications
Sample Stability
- Hemolyzed or severely lipemic samples
- Insufficient sample volume
- Improper labeling or missing patient information
- Samples stored beyond stability periods
Understanding Your Results
Negative (< 20 U/mL)
No significant IgG antibodies detected. Low likelihood of current or past Aspergillus infection.
Equivocal (20-30 U/mL)
Borderline results; consider repeat testing or additional diagnostics.
Positive (> 30 U/mL)
Elevated IgG antibodies indicate exposure to Aspergillus. May suggest allergy, infection, or past infection. Consult a specialist for further evaluation.
If you experience persistent respiratory symptoms, have a weakened immune system, or receive positive test results, consult a healthcare provider for comprehensive assessment and management.
Limitations
- ⚠Presence of IgG antibodies alone does not confirm an active infection, as antibodies can persist after clearance
- ⚠False negatives possible in early stages of infection or in immunocompromised patients
- ⚠Results must be correlated with clinical findings and other tests for accurate diagnosis
- ⚠Cannot differentiate between different Aspergillus species
Risks & Considerations
- ●Minor pain or bruising at the puncture site
- ●Rare risk of infection or excessive bleeding
- ●Fainting in sensitive individuals
Interfering Factors
- ●Use of immunosuppressive medications may affect antibody levels
- ●Cross-reactivity with other fungal infections
- ●Timing of exposure; early infections may not show elevated IgG
- ●Hemolyzed or lipemic samples can interfere with assay
