Understanding Lab Tests for Chronic Sinusitis

Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025

Chronic sinusitis is a condition where the sinuses remain inflamed and swollen for 12 weeks or longer, despite treatment attempts. While chronic sinusitis is typically diagnosed through physical examination and imaging studies, blood testing plays a crucial role in identifying underlying allergic triggers that may be contributing to the persistent inflammation.

Top Recommended Test

Respiratory Allergy Panel Region IV: FL, south of Orlando

This comprehensive panel tests for multiple respiratory allergens common to the Florida region. Frequent exposure to regional allergens like molds can lead to chronic sinusitis, characterized by inflamed and swollen sinuses. Identifying specific regional triggers helps guide avoidance strategies and treatment.

Why Blood Testing is Important for Chronic Sinusitis

There is no single blood test to diagnose chronic sinusitis itself; however, allergy testing through blood work is fundamental for identifying specific environmental triggers that may be causing or worsening the condition. By detecting allergic sensitivities, healthcare providers can develop targeted treatment plans to reduce exposure and manage symptoms more effectively.

Other Relevant Tests

Chicken Droppings (e218) IgE

This test measures IgE antibodies specific to chicken droppings. Long-term exposure to chicken droppings, as indicated by the presence of IgE antibodies, can cause chronic inflammation of the sinuses, resulting in chronic sinusitis. This is particularly relevant for individuals with occupational or residential exposure to poultry environments.

Allergen Specific IgE Iodine Bush

This test detects IgE antibodies to iodine bush, a plant allergen. Chronic sinusitis can be exacerbated by allergies, including to the iodine bush. If levels of this biomarker are high, it could suggest that the individual's sinusitis is being affected by this specific plant allergen, allowing for targeted avoidance measures.

Understanding Your Results

Elevated IgE levels to specific allergens indicate an allergic sensitivity that may be contributing to chronic sinus inflammation. These results help healthcare providers recommend environmental modifications, medications, or immunotherapy to reduce allergic triggers and improve sinusitis symptoms.
