The Extended test is a three part test kit for detailed assessment of a patient’s olfactory capability.
The threshold test provides a measure of odour sensitivity to the standard odourant. This test is analogous to a hearing test to find how quiet of a sound a person can hear.
The discrimination test investigates if a patient can select an odour odour from a triad of two pens with the same odour and one pen with a second odour.
The identification test confirms the patient can identify odours either with free response or through section from multiple choice score card,.
The Extended Test provides a more detailed examination of the patient’s olfactory sense than the Screening 12 test. This test is intended for clinical use.
