Validation of the combined olfactory test

Abstract: A new test of olfactory function, the combined olfactory test, has been designed to assess odours easily recognizable by the test population. The test consists of an odour recognition test of nine odours, where an odour in a bottle is chosen from a list of four possible odours in a forced choice manner. This is followed by a threshold test using a series of three-fold dilutions of 1-butanol. The mean of the two scores is the combined olfactory score. The test was subjected to a validation study. It was perform… Show more

“…A significant number of ENT patients complain of a reduction in their olfactory function with a variety of causes including sinonasal disease, post‐infectious disorders and head injuries. Previous work at this centre using the UK validated Combined Olfactory Test 1 has shown the need for olfactory testing in the Ear Nose and Throat clinic 2 . Furthermore, with the advent of a dedicated Olfactory and Gustatory Disorders Clinic at the James Paget University Hospital, it became important to ensure that the use of the “Sniffin’ Sticks” test was suitable for our local population.…”

“…Assessment of olfactory thresholds allows quantification of any olfactory deficits somewhat akin to determining a frequency threshold in audiometry. As it stands the LOM2 does not allow for qualitative olfactory assessment as possible with the UPSIT (1) or Combined Olfactory Test (8) or discrimination as also possible with Sniffin' Sticks (3) . This deficiency is however the subject of ongoing research and development in our centre and other adaptations will include further automation of the test and the inclusion of half log steps in the threshold testing.…”

“…A plethora of quantitative and qualitative test kits for the assessment of olfactory function have been devised around the world. Some of the more publicised ones include the University of Pennsylvania Smell Identification Test (UPSIT) (1,2) and the Sniffin' Sticks (3)(4)(5)(6) , with other less well publicised tests such as the Combined Olfactory Test (COT) (7,8) , Connecticut Chemosensory Research Test (CCCRT) (9) , Barcelona Smell Test -24 (BAST-24) (10) , and Japanese Odour Sticks (11) receiving less coverage in the medical literature. The tests listed above all comprise psychophysical tests and while there are now more objective tests available in the form of olfactory Event Related Potentials (oERPs) (12,13) , with functional Magnetic Resonance Imaging (fMRI) around the corner (14) , these remain time consuming, costly and the realm of specialist chemosensory centres.…”
