CA19-9

The Cabbage IgE test is essential for diagnosing cabbage allergies by measuring IgE antibodies in the serum. It identifies allergens causing symptoms like rash, hives, and nausea. Key points include:

- Purpose: Diagnose cabbage allergy, confirm sensitization before immunotherapy.
- Specimen: Serum sample, 0.3 mL minimum.
- Stability: Refrigerate at 2-8°C for 14 days or freeze at -20°C for 90 days.
- Methodology: Fluorescence Enzyme Immunoassay (FEIA).
- Results Interpretation: IgE levels indicate allergy likelihood, classified from Class 0 (negative) to Class 6 (very high positive).

This test aids in effective allergy management.

Understanding test results is crucial for managing allergies effectively. The Cabbage IgE test measures specific IgE antibodies to assess allergic reactions to cabbage. Here's how to interpret the results:

- Class 0: <0.10 kU/L - Negative
- Class 0/1: 0.10-0.34 kU/L - Equivocal
- Class 1: 0.35-0.69 kU/L - Low Positive
- Class 2: 0.70-3.49 kU/L - Moderate Positive
- Class 3: 3.50-17.49 kU/L - High Positive
- Class 4-6: >17.50 kU/L - Very High Positive

Higher classes indicate a stronger likelihood of an allergic reaction. Always consider clinical context when interpreting results.
