What tests will be done to diagnose dysgeusia?

You may need to undergo diagnostic tests to further evaluate your altered sense of taste. Your provider may first start with a smell identification test to see if your dysgeusia is linked to anosmia (loss of sense of smell). Your provider may also proceed with taste threshold or flavor discrimination assessments.

If your provider suspects that nutritional deficiencies are causing your dysgeusia, then they may recommend blood tests, such as a complete blood count (CBC). They can also run tests to measure your potassium, calcium, iron and vitamin B12 levels.

If your provider is concerned that a growth or structural abnormality could be causing your altered sense of taste, then they may perform imaging tests, such as X-rays, CT (computed tomography) scans or magnetic resonance imaging (MRI).
