Allergen, Weed, Sagebrush/Wormwood
Also known as: SAGE
Use
This test is used to quantitatively measure specific IgE antibodies to the allergen Sagebrush/Wormwood. It is particularly significant for individuals suspected of having an allergic reaction to this particular weed allergen. The levels of allergen-specific IgE can aid specialists in determining the likelihood of an IgE-mediated clinical reaction upon exposure to the allergen.
Special Instructions
Multiple patient encounters should be avoided to ensure reliable results. Ensure specimen is processed and transported promptly to maintain integrity. Refer to 'Allergen Specimen Collection Instructions' for detailed guidance when ordering multiple allergen tests.
Limitations
Allergen-specific IgE concentrations measured by this assay may not directly correlate with the severity of clinical allergic responses or skin test results. A negative result does not rule out the possibility of a clinical allergy or anaphylactic reaction. The clinical relevance of results in the range of 0.10-0.34 kU/L is undetermined and should be used cautiously by specialists.
