Nerve Conduction Velocity
NCV
Description
"Nerve Conduction Velocity" (NCV) test evaluates how fast electrical impulses move through your nerves. It’s used to investigate symptoms like tingling, weakness, or numbness linked to conditions such as peripheral neuropathy or carpal tunnel syndrome. Mild electrical signals are applied to your skin to measure nerve response speed. Slower signals may point to nerve compression or damage. Results guide treatment plans including physical therapy, medications, or further testing to restore nerve function.

Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Alcoholic neuropathy (Nerve damage due to alcohol consumption)
Amyloidosis (Buildup of abnormal proteins in organs and tissues)
Carpal tunnel syndrome (Compression of the median nerve in the wrist)
Charcot-Marie-Tooth disease (Inherited neurological disorder affecting peripheral nerves)
Chronic inflammatory demyelinating polyneuropathy (A...
Key Reasons For Testing
Peripheral Nerve Function Evaluation: Assesses nerve function to diagnose neuropathy and carpal tunnel syndrome.
Nerve Damage Detection: Identifies nerve damage and differentiates between neuropathy types.
Diagnosis of Neuromuscular Disorders: Detects conditions like Guillain-Barré syndrome and myasthenia gravis.
Treatment Monitoring: Tracks response to therapy in nerve-related disorders.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
