What to Expect from Allergy Testing for Chronic Sinusitis

Allergy testing may look for sensitivities linked with congestion, sneezing, itching, or seasonal worsening. A skin-prick test or blood test can identify sensitisation to selected allergens, but it does not diagnose chronic sinusitis on its own. The clinician may also consider infection, nasal polyps, structural narrowing, irritation, and medication effects. Your symptoms and examination determine how much weight to give the result.

Note how long symptoms last, whether one or both sides are affected, changes in smell, facial pressure, discharge, and links with dust, pollen, or indoor environments. Bring your medicines and any previous scan or specialist information. Check whether antihistamines need adjustment before skin testing. Once a trigger is identified, discuss exposure reduction and how it fits with the rest of your sinus treatment.

Seek medical review for persistent blockage, facial pain, reduced smell, or discharge that is not settling with the advised plan. Get urgent help for swelling around an eye, vision change, severe headache, confusion, stiff neck, or breathing difficulty. These warning signs need prompt assessment rather than waiting for routine allergy results.

Ask whether allergy is suspected, which allergens will be checked, whether testing changes your sinus treatment, and what other causes should be assessed if the result is negative.
