| Test name | Description | Purpose |
|---|---|---|
| Spinal tap (lumbar puncture) | Needle aspiration of cerebrospinal fluid (CSF) from the lower back | To detect elevated protein levels in CSF, often without increased white blood cells |
| Electromyography (EMG) | Thin needle electrodes are inserted into the muscle to measure electrical activity | To evaluate electrical activity and confirm nerve involvement |
| Nerve conduction studies | Electrodes were placed on the skin to stimulate nerves with small electrical impulses | To assess the speed and strength of signals traveling through the nerve |
| Blood test | To detect infections and inflammatory markers | To rule out other causes and detect recent infection, like Campylobacter jejuni |
| Magnetic resonance imaging | Imaging of the spinal cord and nerves | To exclude other conditions that mimic GBS |
