The negative predictive value of this test is not 100%. Some patients with a history of BPPV will not have a positive test result. The estimated sensitivity is 79%, along with an estimated specificity of 75%. The test may need to be performed more than once, as it is not always easy to demonstrate observable nystagmus that is typical of BPPV.
