Oyster IgE
The Oyster IgG test is a specialized laboratory examination that measures immunoglobulin G (IgG) antibodies specific to oyster proteins in a patient's serum. IgG antibodies play a crucial role in the immune system, providing long-term defense against infections. The presence of these antibodies indicates exposure to oyster proteins, either through consumption or other means. This test is particularly useful in diagnosing and managing food-related complaints, especially when symptoms may be linked to oyster consumption. However, it is important to note that the presence of IgG antibodies does not confirm a food allergy, which is typically associated with IgE antibodies. The test involves collecting a blood sample, separating the serum, and analyzing it using a Fluorescence Enzyme Immunoassay (FEIA). Results are expressed in micrograms per milliliter, with higher values indicating increased levels of oyster-specific IgG. While the test provides valuable insights, it should be used alongside other diagnostic methods for accurate diagnosis and management.

The Oyster IgG test measures IgG antibodies specific to oysters, aiding in diagnosing food-related complaints. Key points include:
- Clinical Utility: Helps identify potential immunologic sensitization to oyster proteins.
- Specimen Collection: Requires a blood sample, processed to obtain serum.
- Methodology: Uses Fluorescence Enzyme Immunoassay (FEIA) for analysis.
- Result Interpretation: Values under 2.0 mcg/mL indicate undetectable IgG levels.
- Limitations: IgG presence doesn't confirm food allergy; further tests may be needed.
- Storage: Serum should be refrigerated or frozen for stability.
- Turnaround: Results typically available in 3-7 business days.
The Oyster IgE test is essential for diagnosing oyster allergies by detecting specific IgE antibodies. It is particularly useful for patients showing symptoms like hives, itching, and anaphylaxis after consuming oysters. The test uses a Fluorescence Enzyme Immunoassay method, requiring a serum sample. Key points include:
- Specimen Requirements: Serum gel tube preferred; minimum 0.3 mL for one allergen.
- Stability: Refrigerate at 2-8°C for 14 days or freeze at -20°C for 90 days.
- Interpretation: Class scores range from 0 (negative) to 6 (strongly positive).
This test aids in confirming sensitization and guiding treatment.
Understanding test results is crucial for interpreting the Oyster IgG test. This test measures IgG antibodies specific to oysters, indicating exposure to oyster proteins. Key points include:
- IgG vs. IgE: IgG indicates a delayed immune response, not an immediate allergy.
- Result Interpretation: Values under 2.0 mcg/mL suggest absent IgG; higher values indicate exposure.
- Clinical Context: Use results alongside other tests for accurate diagnosis.
- Limitations: IgG presence alone doesn't confirm an allergy; further testing may be needed.
Understanding these aspects helps in managing food-related symptoms effectively.
