title: [Development of an olfactory screening test based on the Connecticut test (CCCRC)].
abstract: OBJECTIVE
  To create a screening olfactory test based on the CCCRC (Connecticut Chemosen-sory Clinical Research Center).
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Our test is a valid screening test to be used in patients with nasal poliposis.
