The Nasal Smear for Eosinophils test is a diagnostic test used to identify the presence of eosinophils (a type of white blood cell) in nasal secretions. Eosinophils are commonly associated with allergic reactions and inflammation.

This test is particularly useful in differentiating allergic rhinitis from non-allergic conditions such as infections. A sample is collected from the nasal lining using a swab, which is then examined under a microscope to detect eosinophils.

An increased number of eosinophils in the nasal smear indicates an allergic response, helping doctors diagnose and manage conditions like hay fever and other respiratory allergies.

This test is recommended for individuals who have:

• Persistent sneezing or runny nose
• Nasal congestion or itching
• Suspected allergic rhinitis
• Recurrent nasal symptoms without infection
• Evaluation of respiratory allergies

Doctors may recommend this test to confirm allergy-related nasal conditions.
