Background: Allergic rhinitis (AR) is an IgE-mediated inflammation of nasal mucosa triggered by allergen exposure, affecting 10-40% of global population. Diagnosis relies on clinical history, symptoms like rhinorrhoea, nasal itching, sneezing, >5 eosinophils in 3-5 fields or 20-30 cells single finding indicated positivity, graded as mild, moderate, & severe. Serum IgE was measured via chemiluminescent immunoassay. Results: Mean age was 39.78?15.15 years (range 18-75). Cases had 46% males, 54% females. Mean IgE level was 364.14?339.42 IU/ml in group I vs. 100.62?34.60 in group II (p0.3/HPF. Symptom severity correlated well with eosinophilia grading. Conclusions: Nasal smear eosinophilia and serum IgE aid AR diagnosis, with serum IgE offering better sensitivity and comparable specificity. Nasal eosinophilia is highly specific and links to symptom severity, supporting its routine use.
