With the Screening 12 Test the question whether the patient possesses a normal or decreased olfactory sense can be roughly answered. The patient has to name the smell using a multiple choice form which offers four answers for every pen, only one the answers is correct. A template that goes with the multiple choice forms makes evaluation very simple. This test is a commonly used test within ENT and occupational health and safety services. After performing this screening test you can roughly say whether the test person has anosmia, hyposomy or normosmia. It is based on the identification of every-day odors in the scope of a „multiple-forced-choice“ method. The time required for the execution and evaluation of the test is between 3 and 4 minutes. The test is recommended by the corresponding boards of experts or is established through the publication in renowned specialist journals.
