Sage (Artemisia spp.) IgE
Use
Sage (Artemisia spp.) IgE test is designed to detect the presence of Immunoglobulin E (IgE) antibodies specific to Artemisia species pollen. These antibodies are commonly associated with allergic responses to environmental allergens and are significant in diagnosing hay fever (allergic rhinitis) and other allergic conditions. Patients with sage-related allergies may experience symptoms such as sneezing, itchy eyes, and nasal congestion. Accurate detection and quantification of IgE levels help in devising appropriate allergic intervention and management strategies.
Special Instructions
After collecting the serum specimen, it is necessary to ensure proper centrifugation and aliquoting of 0.5 mL into a plastic vial. This test is suitable for patients suspected of having allergies related to sage pollen. It requires adherence to specified specimen handling instructions to maintain accuracy and reliability of results.
Limitations
This test specifically measures IgE antibodies against sage and may not capture allergies to other pollen types. False negatives may occur if IgE levels are below the detection threshold. Additionally, the presence of gross lipemia in specimens could interfere with test accuracy, hence such samples are rejected. The test should be interpreted within the broader context of patient symptoms and clinical history.
