Which of the following is listed as a special test for Guillain-Barré syndrome?

Guillain-Barré syndrome is diagnosed and characterized best through nerve function testing, specifically electromyography with nerve conduction studies. These tests directly assess how well peripheral nerves transmit signals and how muscles respond, revealing patterns of demyelination and sometimes axonal involvement that are typical of GBS. Findings such as slowed conduction velocity, prolonged distal latencies, conduction block, and abnormal F-waves support the diagnosis and help differentiate GBS from other neurologic conditions. Other options don’t serve as the primary diagnostic test for GBS. Pulmonary function testing is important for monitoring respiratory muscle strength as weakness progresses, but it doesn’t diagnose the disorder. Serum creatinine is a general kidney function marker, not related to neuropathy. CT scan of the brain isn’t useful for diagnosing a peripheral nerve inflammatory polyneuropathy like GBS.
