What Is an NCV Test?
The NCV (Nerve Conduction Velocity) test is a medical diagnostic procedure that measures how quickly electrical signals travel through your nerves. It helps doctors assess whether a nerve is damaged and the severity of the damage. The test is usually performed alongside an Electromyography (EMG) to get a complete picture of nerve and muscle function.
The NCV test involves placing small electrodes on your skin over specific nerves. These electrodes deliver mild electrical impulses, and sensors record the speed and strength of the signals as they travel along the nerve. If the signal is slower or weaker than normal, it may indicate nerve damage due to conditions such as peripheral neuropathy, carpal tunnel syndrome, or nerve compression.
Why Is the NCV Test Performed?
The NCV test is recommended when you have symptoms that suggest a problem with your peripheral nerves. Some common reasons your doctor may suggest this test include:
- Tingling or numbness in the arms, legs, or hands
- Weakness or loss of muscle control
- Chronic pain in certain body parts
- Burning sensations in the limbs
- Nerve injuries due to accidents or medical conditions
- It also helps in diagnosing specific disorders like:
- Peripheral neuropathy (common in diabetes)
- Carpal tunnel syndrome
- Sciatic nerve problems
- Herniated disc-related nerve compression
- Guillain-Barré syndrome
- Muscular dystrophy
The results of the NCV test assist doctors in determining the exact location and extent of nerve damage, allowing for targeted treatment and therapy.
NCV Test Procedure: What to Expect
The NCV test is simple, safe, and non-invasive. Here’s how the procedure typically works:
Preparation: You’ll be asked to remove any jewellery and wear comfortable clothing. The test area will be cleaned to ensure proper electrode contact.
Electrode Placement: Small electrodes (both stimulating and recording types) are attached to your skin over the nerve being tested. These electrodes are connected to a monitoring device.
Stimulation: A mild electrical pulse is delivered through one electrode, stimulating the nerve. The other electrode measures the time it takes for the electrical signal to travel along the nerve.
Recording the Response: The speed and strength of the nerve signal are recorded on a graph. The process is repeated for other nerves if required.
Duration: The entire test usually takes 30 to 60 minutes, depending on how many nerves need to be tested.
Results: Your doctor will interpret the results and may combine them with other tests, such as EMG, to reach a diagnosis.
Most patients experience only mild discomfort during the stimulation phase. There are no long-term side effects, and you can resume normal activities immediately after the test.
How to Prepare for the NCV Test
Proper preparation ensures accurate results. Here are a few things to keep in mind before your test:
Avoid using lotions or oils on the skin before the test.
Inform your doctor about any medications you’re taking.
Notify the technician if you have a pacemaker or other electrical devices in your body.
Wear loose clothing for easy electrode placement.
Factors Affecting NCV Test Price
The NCV test price can vary depending on several factors, including:
Location and City:
The cost differs between cities due to variations in living standards and medical infrastructure.
Type of Diagnostic Centre:
Private diagnostic centres may charge more than government or charitable medical institutions.
Inclusion of EMG Test:
Many times, the NCV test is performed alongside an Electromyography test, which can increase the total cost.
Number of Nerves Tested:
The price may depend on how many nerves or body parts need to be examined.
Doctor’s Fees and Consultation Charges:
Specialist consultation and interpretation fees may also be included in the final bill.
Average NCV Test Price in India
The average NCV test price in India ranges from ₹2400 to ₹5,000. However, this range can vary based on the factors mentioned above. In some major cities like Delhi, especially if both arms or legs are being tested.
Here’s an approximate breakdown by city:
Benefits of the NCV Test
The NCV test offers several key benefits:
Accurate Diagnosis: Helps in pinpointing nerve damage quickly and effectively.
Early Detection: Enables timely treatment before the condition worsens.
Non-Invasive: No needles or surgery are required.
Fast Results: Reports are often available within 24–48 hours.
Guides Treatment: Helps doctors customise your therapy or rehabilitation plan.
Where to Get an NCV Test Done
NCV tests are available at diagnostic centres, neurology clinics, and multispecialty hospitals. Many centres now offer online appointment booking, home sample collection (for related tests), and digital report delivery. Always choose a diagnostic centre with modern equipment and experienced neurologists to ensure accurate results.
Conclusion
The NCV test is a vital diagnostic tool for evaluating nerve health and detecting various neurological conditions. Understanding the NCV test price, along with the procedure and benefits, can help you plan your diagnostic journey better. Early detection through an NCV test can prevent complications and ensure timely treatment, leading to better nerve function and overall well-being.
