What is the ImmunoCAP Specific IgE Blood Test?
A laboratory test to rule in or rule out atopy in patients with allergy-like symptoms. ImmunoCAP provides a clinically relevant means of confirming or excluding the presence of atopic disease in patients with upper respiratory disease. These allergy-like symptoms are very difficult to differentiate. ImmunoCAP will also accurately identify specific allergen sensitivities in patients with confirmed allergy.
What Does the Test Measure?
This in vitro quantitative assay measures allergen specific IgE in human serum. It is intended for in vitro diagnosis use as an aid in the clinical diagnosis of IgE mediated allergic disorders in conjunction with other clinical findings. ImmunoCAP assays can be performed on hundreds of allergens such as weeds, trees, pollens, mold, food, and animal dander.
What is the Role of this Test in Diagnosing and Managing Upper Respiratory Disease?
Causes of nasal symptoms associated with upper respiratory disease (URD) can range from aspirin intolerance to pregnancy. The exact etiology of allergy-like symptoms is often difficult to determine definitively. The origin could be allergic, bacterial, viral, or pathological and is virtually impossible to establish with an empirical assessment alone. Compounding this, consumer awareness is at an all-time high. Patients often come in with a pre-determined self-diagnosis and request for therapy. History and physical are important, but further inquiry is often necessary to provide an evidence-based diagnosis and treatment regimen. ImmnoCAP Specific IgE blood test can definitively rule in or rule out atopic disease as the cause of or contributing factor to these symptoms.
Once a definitive diagnosis is reached, regardless of the presence or absence of atopy, appropriate treatment options can be employed. When atopy proves to be a factor in URD, avoidance is considered the primary therapeutic approach by all leading professional allergy associations. This test can identify the specific causative allergens.
