This test is used if you have fainting spells for no known reason. For the test, you lie on a table that moves from a lying down to an upright position. Your doctor checks your reaction to the change in position.
Doctors use a tilt table test to diagnose orthostatic hypotension and neurally mediated hypotension (NMH). People who have NMH usually faint during this test. The test can help your doctor find any underlying brain or nerve condition.
