About This Test
Nerve Conduction Velocity (NCV) testing assesses how fast and efficiently nerves carry electrical signals. When performed on the all limbs, NCV helps diagnose common nerve disorders such as carpal tunnel syndrome, ulnar nerve compression, radiculopathy, sciatica, and peripheral neuropathy. During the test, small electrical pulses stimulate the nerves, and electrodes placed along the nerve pathway measure how quickly the signal travels. NCV identifies nerve damage, its location, and its severity. It helps distinguish between nerve compression, demyelination (damage to nerve covering), and axonal loss (damage to the nerve fiber itself). The test is essential for patients with numbness, tingling, burning sensations, muscle weakness, or unexplained limb pain. When paired with EMG, NCV offers a full picture of nerve and muscle function. It is a safe and non-invasive study.

TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test
- Scan time or sample collection time
In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
