Oyster IgE

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 managing oyster allergies effectively. The Oyster IgE test results are interpreted using a class score system, which helps determine the likelihood of an allergic reaction. Key points include:

- Class 0: Negative (<0.10 kU/L)
- Class 1: Low Positive (0.35-0.69 kU/L)
- Class 2: Moderate Positive (0.70-3.49 kU/L)
- Class 3-6: Increasingly High Positive (≥3.50 kU/L)

A higher class score indicates a stronger allergic response. Understanding these results aids in confirming sensitization and guiding treatment plans.
