Desarrollar un test de screening olfatorio, basado en el test de Connecticut, con un coste reducido y con una fiabilidad suficiente. El test de screening está compuesto por la dilución 3 de butanol y por el café, chocolate y naftalina. Nuestro test se compara con el Pocket Smell Test (PST) basado en el test de UPSIT. Indice de validez del 95% y grado de precisión de la prueba 10%. La sensibilidad es del 88% y la especificidad del 77%. El valor predictivo positivo es del 34% y el valor predictivo negativo del 94%. El tiempo medio de realización es de 2,8±0,4 minutos. El coste unitario del test es de 0,57 si lo realiza un auxiliar de consulta. El 96% de los pacientes refieren que el test es muy fácil de realizar. El test de screening basado en el CCCRC es una prueba válida y útil para el screening olfatorio. To create a screening olfactory test based on the CCCRC (Connecticut Chemosen-sory Clinical Research Center). We compare the screening test based on CCCRC with PST (Pocket Smell Test) based on UPSIT in 40 patients with nasal poliposis, in order to de-termine the specificity, sensitivity, positive predictive and negative predictive value. The validity index was 95% and accuracy rate was 10%. We determine unit cost, the time required to perform the test in outpatients office and how difficult it is to do the test. Sensibility was 88%, specificity was 77%. The positive predictive value was 34% and the negative predictive value was 94%. The unitary cost of our screening test was 0.57 euros when it is performed by a nurse. The unitary cost of PST is 1.76 euros. To perform our screening test took 2.8±0.4 minutes. The 96% of the patients thought the test was easy to do. Our test is a valid screening test to be used in patients with nasal poliposis.
