There is no specific test for essential tremor. Determining the diagnosis is often a matter of ruling out other conditions that could be causing your symptoms. To do this, your doctor may suggest the following:

Neurological exam
This exam involves checking your:

  • Tendon reflexes
  • Muscle strength and tone
  • Ability to feel certain sensations
  • Posture and coordination

Laboratory tests
Your blood and urine may be tested for problems such as:

  • Thyroid disease
  • Drug side effects

Performance tests
To evaluate the tremor itself, you may be asked to:

  • Drink from a glass
  • Hold your arms outstretched
  • Write
  • Draw a spiral
