\u00a0What Is an NCV Test?<\/b><\/h3>\n
A<\/span> NCV test<\/b><\/a> or Nerve Conduction Study (NCS) is a medical test which analyzes the speed and effectiveness of electrical activity that passes through your nerves. All the nerves of our body contain electrical signals which transfer information from our brain, spinal cord, and muscles. In case when there is some injury, pressure, or disease of the nerve, the speed and strength of these signals become lower.<\/span><\/p>\n In the course of the NCV\u00a0 test, some electrodes are attached to the skin over certain nerves, and then a weak electrical signal is delivered to the nerve. The speed and strength of electrical signals are measured and analyzed by the electrodes at the end of their travel.<\/span><\/p>\n The most frequently examined areas by NCV tests are the nerves of the arms, hands, legs, and feet.<\/span><\/p>\n Numbness occurs due to nerve dysfunction that prevents the transmission of sensory signals to the brain. However, the presence of numbness does not provide any information regarding which nerve has been affected, the location of the problem on its path, and the severity of the impairment. That is precisely what the NCV test<\/strong> is used for.<\/span><\/p>\n The main reasons to use the NCV test<\/strong> for numbness are as follows:<\/span><\/p>\n Confirm that the numbness occurs due to nerve injury and not other causes, such as circulation problems, muscular disorders, or issues with the spine Identify the specific nerve and the location of the problem, e.g., a nerve in the wrist for carpal tunnel syndrome, or a nerve in the spine in the case of sciatica Identify problems in nerve conduction and contribute to the assessment of conditions such as carpal tunnel syndrome, peripheral neuropathy, and certain nerve problems linked to radiculopathy Evaluate the extent of nerve damage<\/span><\/p>\n Monitor the development or improvement of a condition such as diabetic neuropathy<\/span><\/p>\n Exclude or diagnose a condition such as Guillain-Barr\u00e9 Syndrome, peripheral neuropathy, or nerve entrapment<\/span><\/p>\n Numbness can have multiple causes, and therefore the NCV test provides doctors with objective measurements of nerve function rather than the symptoms reported by patients.<\/span><\/p>\n Numbness in the hands and legs can result from a wide range of conditions, including:<\/span><\/p>\n Since many of these causes overlap in symptoms, an NCV test helps narrow down the actual source of the problem rather than leaving it to guesswork.<\/span><\/p>\n Not every instance of numbness needs testing \u2014 a foot that “falls asleep” after sitting cross-legged usually resolves on its own. However, doctors generally recommend an NCV test when numbness is accompanied by:<\/span><\/p>\n If you’re experiencing any of these persistently, it’s worth discussing an NCV test with your doctor rather than waiting for symptoms to worsen.<\/span><\/p>\n The NCV test is a straightforward outpatient procedure that usually takes between 30 minutes to an hour, depending on how many limbs or nerves are being studied. Here’s what typically happens:<\/span><\/p>\n There’s no downtime after the test, and you can resume your daily activities right away. No fasting or sedation is required.<\/span><\/p>\n One of the most important uses of the NCV test is diagnosing and evaluating <\/span>peripheral neuropathy<\/b> \u2014 damage to the nerves outside the brain and spinal cord that most commonly affects the hands and feet.<\/span><\/p>\n The test helps doctors distinguish between two broad categories of nerve damage:<\/span><\/p>\n This distinction matters because it guides treatment. For example, diabetic neuropathy, alcohol-related neuropathy, and vitamin deficiency-related nerve damage often show different NCV patterns compared to autoimmune or compression-related nerve disorders. NCV testing, often paired with an EMG, gives doctors a clearer picture of the type, location, and severity of nerve damage \u2014 helping shape a more targeted treatment plan.<\/span><\/p>\n NCV test cost in determined primarily depending on the number of limbs that need to be examined, the diagnosis center, and whether the test is taken along with an EMG test. At <\/span>Goodhealth21 Diagnostics<\/b>, we conduct NCV tests for either two limbs or four limbs, as recommended by your doctor:<\/span><\/p>\n NCV Test for Two Limbs: \u20b93,500 – \u20b95,000<\/b><\/p>\n NCV Test for Four Limbs: \u20b95,000 – \u20b97,000<\/b><\/p>\n The number of limbs for which the NCV test is to be done is normally determined by your doctor according to your condition, e.g., if the numbness is restricted to either one side of your body or a particular limb, then only two limbs need to be evaluated for the test, whereas if you have general or bilateral numbness, then all four limbs should be included for a comprehensive nerve evaluation. It would be wise to check from your doctor how many limbs need to be tested, and also whether the report is to be reviewed by a neurologist.<\/span><\/p>\n For patients who find it difficult to travel \u2014 due to mobility issues, old age, or a busy schedule \u2014 many diagnostic centres in Delhi now offer <\/span>NCV testing at home<\/b>. A trained neuro-technician visits with portable NCV equipment and performs the test in the comfort of your home, following the same process used in a clinical setting.<\/span><\/p>\n Home NCV testing is particularly useful for:<\/span><\/p>\n The report is typically shared digitally, and in most cases a neurologist reviews the results just as they would for an in-centre test. If you’re considering this option, it’s worth confirming the technician’s experience and whether the same equipment and standards used in-lab are followed at home. Goodhealth21 Diagnostics provides home NCV testing in selected areas of Delhi, subject to service availability. , so you get the same accuracy without having to travel.<\/span><\/p>\n NCV and EMG (Electromyography) are often mentioned together, and doctors frequently recommend them as a combined study \u2014 but they test different things.<\/span><\/p>\nWhy Is an NCV Test Done for Numbness?<\/b><\/h2>\n
