The laboratory analysis conducted on a child with chronic nasal drainage reveals an elevated number of eosinophils on a white blood cell differential. Based on this finding, which is most likely the cause of the nasal drainage?

a. Bacterial infection

b. Viral infection

c. Chronic inflammation

d. Allergies

Answer: d. Allergies

Explanation:

During the allergy the eosinophils are recruited at the site and these are produced in large number by the bone marrow cells. The allergic conditions may developed during the sinus infections where chronic nasal drainage occurs in order to expel out the pathogen from the body. The parasitic diseases and allergic reactions will result in the excess production of the eosinophils.

The given situation is a result of the allergic reaction which brought about large increase in the number of eosinophils.
