Laboratory analysis of a blood sample can identify specific antibodies produced in response to venom from stinging insects, such as bees. These tests measure the quantity of these antibodies, providing information about the likelihood of a systemic allergic reaction to a future sting. For example, a high level of immunoglobulin E (IgE) antibodies specific to bee venom indicates sensitization and a higher risk of an allergic reaction.
Understanding an individual’s sensitization status is crucial for managing potential sting reactions. Accurate diagnosis informs appropriate preventative measures, including venom immunotherapy, which can significantly reduce the risk of severe or life-threatening reactions. Historically, diagnosis relied heavily on skin testing, but serum-based testing provides a valuable alternative, especially for individuals with skin conditions or those taking medications that could interfere with skin test results. This advancement has broadened access to safe and effective allergy diagnosis.
