These conditions are more recognizable to an experienced clinician, as they can be clearly demarcated diagnostically. However, additional 30% 50% of patients with CR might have overlap NAR AR, referred mixed (MR). Progress in elucidating the pathophysiologic mechanisms behind MR has been made past several years, there now guidelines published assist clinician accurately diagnosing NAR, MR. Clinical history subjective symptoms provide clues for differentiating AR from but allergy testing recommended confirm these conditions. will studies incorporate (i.e., validated questionnaires such irritant index questionnaire (IIQ), medication responsiveness, quality-of-life tools) objective nasal cytologic testing, provocation, biomarkers) methods characterizing subtypes.
