Dry nose (DN) is a common symptom in both patients with rhinitis and healthy individuals; however, it is often overlooked.

This study aimed to investigate the characteristics of and propose objective diagnostic criteria for DN.

This study was conducted from December, 2018 to October, 2021.

Patients with complaints of a dry nasal cavity and normal controls were recruited consecutively from the allergy-rhinology outpatient clinic of Beijing TongRen Hospital.

Questionnaires were completed by each participant during recruitment to record demographic data. DN test strips were used to evaluate the severity of DN.

The length of the strip was recorded at 30 s, 1 min, 2 min, 3 min, 4 min, and 5 min, respectively. Nasal secretions were collected on sponges and allergic status was assessed based on serum sage levels.
