Runny Nose (Diagnosis)

How is runny nose diagnosed?

Runny nose itself is a prominent symptom, but additional symptoms might prove underlying conditions that may need to be diagnosed.

In worst-case scenarios, as mentioned before, when visiting the doctor, one can expect the following things.

Allergy tests:

Both skin and blood tests may be conducted to identify if the cause is an allergic reaction to any particles. Skin allergy tests can help identify allergens.

Blood tests:

• Complete Blood Count (CBC): can identify the amount of red blood cells, white blood cells and other components like haemoglobin and platelets.

• Blood differential test: to identify autoimmune diseases, infections and other forms of cancer by measuring each type of white blood cells.

Sputum and throat culture:

Samples of sputum, a thick fluid which forms in the lungs and the adjacent airway and throat culture samples are taken to identify if the cause is a bacterial or fungal infection.

Imaging tests:

X-rays of the sinuses and the chest may be taken to understand the spread of the infection.

CT scans may also be suggested to get a better and accurate picture of the condition.
