Nasal Smear For Eosinophils

Illinois rates for HCPCS 89190

A sample of mucus or cells from inside the nose is spread on a slide, stained and examined under a microscope for eosinophils, a white blood cell that gathers where there is an allergic reaction. Plenty of these cells points toward allergy as the cause of nasal symptoms.
