IgE antibodies appear in human serum and plasma as a result of sensitization to a specific allergen. While clinical presentation and patient history may offer numerous possible causes of symptoms, diagnostic testing can narrow those possibilities and improve confidence in a diagnosis.1,2 enabling you to provide treatment tailored to your patient’s individual needs.
Diagnostic testing for allergic sensitization provides various benefits, including:
If the patient history suggests an IgE-mediated allergy, specific IgE blood testing can be used to confirm a suspicion of allergy and to determine the offending allergens, or to rule out allergy all together in symptomatic patients.
Measurement of circulating IgE antibodies provides an objective assessment of sensitization to an allergen. In general, low IgE antibody levels indicate a low probability of clinical disease, whereas high antibody levels to an allergen show good correlation with clinical disease.4
A standard blood test is convenient—and can test your patients from among over 550 whole allergens and mixes, such as weeds, trees, grasses, pollen, food, and animal dander. Tests are simple to perform, and can be done irrespective of age, skin condition, antihistamine use, or pregnancy.5-7
