Quick answer
The Sage (Salvia) Allergy Test is a blood test that measures IgE antibodies against proteins from the sage plant. It is ordered when a person reports symptoms such as itching, hives, or respiratory irritation after handling or eating sage. The test shows whether sensitization is present and is interpreted with the person's exposure and symptom history.
What this test measures
Sage is an herb in the mint family, used in cooking, teas, and some personal care products. Its leaves contain proteins and aromatic compounds that can act as allergens in sensitized people. The test measures specific IgE against sage proteins in the blood, which indicates whether the immune system has been primed to respond.
Only a blood sample is required, and results are reported as a concentration in kilounits per liter with a graded class. Sage belongs to a family that includes other culinary herbs, so a broader panel may include basil, oregano, mint, and thyme to check for related reactions. This helps show whether sensitivity is specific to sage or extends to other herbs.
People may seek testing after oral itching, skin reactions, or respiratory symptoms following contact with sage. It can also be included when a food or herbal allergy panel is assembled. A qualified healthcare provider interprets the result with the person's symptoms, timing, and other allergy findings.
- Sage (Salvia)-specific IgE antibodies
- Quantitative IgE to sage in kU/L
- Allergen-specific IgE antibody class
- Total serum IgE when included
- Serum eosinophil count when included
- Related herb allergens when a broader panel is ordered
- Common pollen allergens when included as cross-reactive markers
Why people order this test
- Evaluate reactions after eating or handling sage
- Check sensitization when herbal teas or seasonings trigger symptoms
- Distinguish sage allergy from reactions to other culinary herbs
- Add sage to a broader food or herb allergy workup
- Investigate skin or respiratory symptoms linked to sage exposure
How to prepare
No fasting is needed, and the blood sample can be collected at any time. Follow the lab's standard instructions for blood draws.
Understanding your results
Results are usually available within one to three business days. A measurable IgE level indicates sensitization to sage proteins and does not prove that exposure will cause symptoms. A qualified healthcare provider interprets the result with the person's reaction history and other allergy results.

Frequently Asked Questions
Is sage allergy related to other herb allergies?
Sage is in the mint family, and reactions to related herbs such as mint, basil, or oregano can occur. A broader panel can show whether cross-reactivity is present.
Can sage cause skin reactions?
Contact with sage can cause skin irritation or allergic skin symptoms in some people. A clinician can evaluate the pattern and test results.
Does cooking sage remove the allergen?
Cooking changes some proteins but does not necessarily remove allergenic potential for every person. The clinical history guides the assessment.
Do I need to stop using sage before the test?
No. Blood antibody testing does not require avoiding the substance beforehand unless a clinician requests it.
Can this test be done alongside food allergy testing?
Yes. Sage can be included in a broader food or herb panel when a clinician considers it useful.
