Blink Reflex NCV is a specialized electrophysiological test that evaluates the neural pathways involved in the blink response, including the trigeminal and facial nerves and their brainstem connections. It is performed to investigate facial weakness, facial numbness, trigeminal nerve disorders, facial nerve dysfunction, and other neurological conditions, helping localize nerve or brainstem abnormalities for accurate diagnosis and treatment planning.

Yes. It can provide objective information about facial nerve dysfunction and may help localize abnormalities along the facial nerve pathway, particularly when combined with clinical examination and other electrodiagnostic tests.
Depending on the findings, your doctor may recommend additional tests such as Facial NCV, EMG, MRI of the brain or brainstem, or other neurological investigations.
Small electrodes are placed on the face, and mild electrical stimulation is applied to specific nerves while the blink response is recorded.
You may feel mild discomfort from the electrical stimulation, but the test is generally well tolerated.
Yes, unless your doctor advises otherwise. Inform your doctor about all medications you are taking.
Individuals with facial weakness, facial numbness, abnormal blinking, facial pain, or suspected cranial nerve disorders may be advised to undergo this test.
