What tests should be done to check for rhinitis

Checking for rhinitis usually requires anterior nasal examination, nasal endoscopy, allergen testing, imaging examination, and nasal function examination. These tests can help doctors clarify the type and severity of rhinitis and rule out other nasal diseases.

1. Front nasal examination:

This is the most basic examination, and the doctor uses a front nasal examination to observe the anterior part of the nasal cavity. You can visually see whether the nasal mucosa is congested or swollen, whether the nasal turbinates are enlarged, and whether there are secretions, polyps, or new organisms in the nasal cavity. This examination can preliminarily determine the presence of rhinitis and provide a basic understanding of the severity of inflammation.

2. Nasal endoscopy:

Nasal endoscopy can penetrate deep into the posterior nasal cavity and nasopharynx, providing a clearer and more comprehensive view. It is possible to clearly observe hidden areas such as sinus openings and olfactory slits, and detect lesions that are difficult to see through the anterior nasal cannula, such as nasal polyps, sinusitis, adenoid hypertrophy, or early tumors. It is very important for diagnosing chronic rhinitis, allergic rhinitis, and distinguishing the types of rhinitis.

3. Allergen testing:

If allergic rhinitis is suspected, allergen testing is required. Common methods include skin prick test and serum specific IgE detection. It is possible to identify which substances the patient is allergic to, such as dust mites, pollen, mold, animal dander, etc. Identifying allergens is a key basis for developing contact avoidance measures and conducting specific immunotherapy (desensitization therapy).

4. Imaging examination:

When rhinitis is suspected to be accompanied by sinusitis, nasal polyps, or nasal structural abnormalities, doctors may recommend performing sinus CT examination. CT scan can clearly display the detailed condition of the sinus, nasal bone structure, and mucosa, helping to evaluate the extent of the lesion, whether there is bone destruction or sinus blockage. For patients with chronic sinusitis or nasal polyps who require surgical treatment, CT examination is an essential preoperative evaluation tool.

5. Nasal function examination:

mainly includes nasal resistance measurement and nasal acoustic reflex measurement. Nasal resistance measurement can objectively evaluate nasal ventilation function and determine the degree of nasal congestion. Nasal acoustic reflex measurement can reflect the geometric shape and cross-sectional area of the nasal cavity, helping to analyze the specific causes of nasal congestion. These examinations have important reference value for evaluating treatment effectiveness and distinguishing structural rhinitis from functional rhinitis. After completing the above examinations, the doctor will develop an individualized treatment plan based on the results. Daily attention should be paid to keeping indoor air moist and avoiding contact with known allergens and irritating gases, such as second-hand smoke, dust, etc. If symptoms such as nasal congestion, runny nose, and sneezing persist or worsen, it is necessary to seek medical attention promptly for follow-up examination and adjust treatment strategies. Meanwhile, moderate physical exercise can enhance immunity and help reduce the frequency of rhinitis attacks.
