Chronic rhinosinusitis (CRS) causes high annual medical cost and decreases quality of life. Researches continue with easier, cheaper and saver approach. This study evaluate nasal secretion disptick assay (NSDA) correlation with Lund-Mackay Score (LMS) in CRS. Its an analytic cross-sectional study. Middle meatus nasal secretion obtained with absorption method, applied to dipstick to read qualitatively. Statistical correlation and sensitivity analysis performed. Most patients are men (59 %), 15-24 age group (33.3 %), CRS without nasal polyps (71.1 %), maxillary involvement (92.3 %). LMS correlation with acidity, leukocyte esterase, nitrit, protein and total score, were statistically significant (pless than0.05, r=0.652; 0.556; 0.605; 0.503; 0.779 respectively). Sensitivity of NDSA to LMS is 92.6 %, specificity 58.3 %, positive preditive value 83.3 % and negative predictive value 77.8 %. Total NSDA has positive strong correlation with LMS. With sensitivity above NSDA can predict LMS value ≥4 in cheaper, easier and saver method.
