Sample

Blood draw or sample collection at a local center

An oregano-specific IgE blood test detects antibodies the immune system may produce against proteins in oregano, a culinary herb. It is a screening tool for suspected herb or food allergy rather than a standalone diagnosis. A clinician may order it after a reaction to oregano-containing food, as part of a broader spice and herb panel, or when a person's history points to sensitivity among aromatic herbs.

• Oregano-specific IgE Antibodies produced in response to oregano proteins, used to assess sensitization.

• Hives, itching, or swelling after eating oregano or herb-seasoned food
• Digestive symptoms following meals that contain oregano
• Respiratory or nasal symptoms around certain dried herbs
• Testing as part of a spice, herb, or food allergy panel
• Reactions to related herbs such as basil, thyme, or sage

• No fasting is required for most IgE allergy tests
• Report antihistamines and other medications to the collector
• Stay hydrated before the blood draw
• No special diet is needed before an oregano-specific IgE test

An elevated oregano-specific IgE level may indicate that the immune system has been sensitized to oregano proteins and can be associated with allergy-like symptoms, but a positive result alone does not confirm a clinical allergy. A low or undetectable level makes allergy less likely without excluding it. A healthcare provider should interpret the result together with your symptoms and history.
