Allergen, Food, Oregano IgE

Also known as: OREGANO

Clinical Use

Order Test

Use

This test measures the concentration of IgE antibodies specific to oregano allergens in the blood, which can help identify potential food allergies. The presence of IgE antibodies suggests a sensitization to oregano, which could indicate a risk of allergic reactions upon ingestion. However, these concentrations may not always correlate with the severity of clinical symptoms or skin testing results. The results should be correlated with the patient's clinical history and in vivo reactions to specific allergens for an accurate diagnosis.

Special Instructions

Multiple patient encounters should be avoided to ensure accurate results. Serum must be separated from cells as soon as possible or within 2 hours of collection.

Limitations

There are inherent limitations in the IgE test for oregano, as increasing concentrations of allergen-specific IgE antibodies may not directly correspond to the intensity of clinical reactions or skin test outcomes when challenged with oregano. Additionally, a negative result does not rule out the possibility of clinical allergy or even anaphylaxis. The correlation of laboratory findings with clinical history and in vivo reactivity is crucial for a comprehensive assessment.
