How to diagnose Problems with Taste ?
Doctors can diagnose a taste disorder by measuring the lowest concentration of a substance that a person can detect. The doctor may also ask a patient to compare the tastes of different substances or to note how the intensity of a taste grows when a substance's concentration is increased. Scientists have developed taste tests in which a person responds to different concentrations of a substance. This may involve a simple "sip, spit, and rinse" test, or the application of a substance directly to the tongue with an eye dropper. By using these tests, your doctor can determine if you have a true taste disorder and what type it is.
