Overview
Laboratory Findings
The presenting symptoms of allergic and nonallergic rhinitis are sometimes difficult to distinguish, and it is often a diagnostic challenge to determine the etiology of rhinitis, whether it is allergic or nonallergic (or even an overlap of the two conditions).[1] The accurate diagnosis allergic rhinitis relies on the clinical history, and the demonstration of the presence of allergic sensitization towards relevant allergens.[2][3] Nonallergic rhinitis is a heterogeneous condition with a wide range of nasal pathological findings, which may require more targeted investigations.[4] Allergy investigations are never used alone for diagnosis because of the low specificity, and the test result should be interpreted in conjunction with the clinical history.[2]
Determination of allergic sensitization is usually done via the following methods:
- Skin prick test, OR
- RAST (radioallergosorbent test)- This is a blood test that detect specific IgE antibodies using radioimmunoassay test
- Nasal allergen challenge- This is not routinely done
