Lyon clinical olfactory test

Identification Test (SOIT), which was developed in Sweden [11] the third test was the Lyon Clinical Olfactory Test (LCOT), developed in France [12]. 

The Lyon Clinical Olfactory Test is based on thresholds, suprathres-hold detection, and identification tasks. The LCOT includes two threshold measurements, one for R-(+)-carvone and the other for tetrahydrothio-phene (THT). The same threshold determination procedure is used for both compounds. Five concentration levels are presented in increasing order with a 4-AFC paradigm. In the suprathreshold detection task 16 odors, presented at a suprathreshold level, have to be detected by following a 4-AFC procedure. The identification task consists of 16 odors to be identified, following a 4-AFC procedure and using verbal alternatives.
