An 8-year-old patient presents to her pediatrician complaining of profuse, watery rhinorrhea, difficulty breathing, and itching of the nose and palate. There is a family history of atopy. During the physical examination, the child has paroxysmal sneezing. The physician suspects that the patient has allergic rhinitis. To substantiate the diagnosis, the physician should perform which of the following tests?
(A) A radioallergosorbent test (RAST)
(B) A Coombs’ test
(C) A nasal smear for eosinophils
(D) A scratch test
(E) Immunoglobulin E (IgE) levels

Scratch testing is considered the primary method for identifying specific allergic triggers of rhinitis.

Scratch tests are generally considered to be more sensitive and cost effective than RAST and have the further advantage of providing physicians and patients with immediate results.

MY reason is that if this question had an option sayin ....

"history and physical exam"

that would be correct...and then UW too says Eosinophils in smear is confirmatory test...

so in exam be careful...

for diagnosis..."hist and exam" is enof..., but if the nature of the question be and requires...to confirm ...then Eosinophils is correct...

even UW says so

:eek:
