The Brewer's Yeast IgE test is crucial for diagnosing allergies to brewer's yeast. It identifies allergen-specific IgE antibodies in the blood, aiding in allergy management. Key points include:

- Purpose: Confirms brewer's yeast allergy, crucial for treatment planning.
- Procedure: Serum sample collection, stored at 4°C or -20°C.
- Methodology: Enzyme immunoassay detects IgE levels.
- Results Interpretation: Class scores from 0 to 5 indicate allergy severity.
- Clinical Utility: Guides immunotherapy and reduces allergic reaction risks.
- Limitations: May not reflect sensitivity post-immunotherapy; false positives possible.

This test is vital for effective allergy diagnosis and management.

Understanding test results is crucial for managing allergies effectively. The Brewer's Yeast IgE test results are expressed as class scores or kU/L, indicating the level of allergen-specific IgE antibodies:

- Class 0: Below detection (<0.35 kU/L)
- Class 1: Low positive (0.35-0.69 kU/L)
- Class 2: Moderate positive (0.70-3.49 kU/L)
- Class 3: Positive (3.50-17.49 kU/L)
- Class 4: Strong positive (17.50-49.99 kU/L)
- Class 5: Very strong positive (>99.99 kU/L)

These results guide healthcare providers in diagnosing allergies and tailoring treatment plans, ensuring patient safety and effective allergy management.
