Diagnosis
The diagnosis of perennial allergic rhinitis is based on a combination of the following criteria:
- Characteristic clinical symptoms by history
- Perennial pattern of symptoms by history (may fluctuate randomly by intensity throughout the year and may flare up following specific allergen exposures)
- Typical physical examination findings
- Positive skin test and/or blood tests for allergic sensitivity for perennial allergens
- Correlation of occurrence of symptoms with exposure to specific allergens noted to be significant on skin test and/or blood test
- Presence of concomitant allergic disorders
- Positive family history
- Presence of complications of perennial allergic rhinitis
