Sample

Blood draw or sample collection at a local center

A sage-specific IgE blood test detects antibodies the immune system may produce against proteins in sage, also known as salvia, a culinary and aromatic herb. It is a screening tool for suspected herb allergy, not a diagnosis on its own. A clinician may order it after a reaction to sage or sage-containing products, as part of a broader herb panel, or when symptoms suggest sensitivity among aromatic herbs.

• Sage (Salvia)-specific IgE Antibodies produced in response to sage proteins, used to assess sensitization.

• Hives, itching, or swelling after eating sage or sage-seasoned food
• Digestive symptoms following meals that contain sage
• Oral tingling or irritation after sage or herbal blends
• Testing as part of a herb or food allergy panel
• Reactions to related herbs such as oregano, thyme, or rosemary

• No fasting is required for most IgE allergy tests
• Inform the collector about antihistamines or other medications you take
• Stay hydrated before the blood draw
• No dietary preparation is needed before testing

An elevated sage-specific IgE level may indicate sensitization to sage 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 ruling it out. A healthcare provider should interpret the result together with your symptoms and history.
