About This Test
EMG + NCV testing of all four limbs is a comprehensive evaluation of nerve and muscle function throughout the body. Nerve Conduction Velocity (NCV) measures how fast electrical signals travel through nerves, while Electromyography (EMG) analyzes muscle activity using small needle electrodes. Together, these tests help diagnose complex or widespread neurological disorders. They are especially useful when patients present with numbness, tingling, weakness, or unexplained pain in multiple limbs. Conditions commonly identified include generalized peripheral neuropathy, diabetic neuropathy, motor neuron diseases, muscular dystrophy, Guillain-Barré syndrome, radiculopathy, and systemic nerve compression disorders. By testing all four limbs, doctors can compare patterns of nerve involvement and determine whether the issue is localized or systemic. The results also help monitor disease progression and determine treatment effectiveness. This combined study provides a detailed and accurate assessment of nerve conduction and muscle health throughout the body.

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.
