[Eosinophils in nasal secretion. Technique and clinical utility].
The microscopic study of nasal secretions to identify eosinophils is a classic test in the diagnosis of allergic rhinitis. Modern immunologic diagnostic alternatives have reduced the frequency of its practice, but the information that it provides, although complementary, is quick, inexpensive and specific. Panoptic stains easily detect eosinophils, although the absence of these cells does not rule out any diagnosis.
