Sense of Smell examination

These sniffing tests are very reliable and accurate to determine olfactory function. Each nasal cavity is examined separately using a series of reusable pen-like odor-dispensing devices.

An alteration in taste or smell may be a secondary process in various disease states, or it may be the primary symptom, therefore it is very important to be detected and diagnosed.
