Qualification Level: A
The extended test consists of 3 separate tests:
- Threshold test 2-Phenylethanol
- Discrimination test
- Identification test 16, blue
Each of these tests generates a number of points that are added to the TDI score at the end. Based on this number of points, a diagnostic classification of the sense of smell can be determined. Total duration of the complete test is 30-40 minutes.
Contents extended test 2-Phenylethanol
- The threshold test has 48 Sniffin’ Sticks (32 blanks and 16 dilutions 2-Phenylethanol). This module can be used to ascertain the patient’s olfactory threshold.
- The discrimination test consists of 48 Sniffin’ Sticks (48 Sniffin’ Sticks = 16 pairs of odorants each with 1 individual smell). In this case, the patient must differentiate between more or less similar smells.
- The identification test (blue version) consists of 16 Sniffin’ Sticks with everyday smells which the patient has to name using a selection card containing four definitions each.
