Cracking the Code: How Doctors Diagnose Guillain-Barré Syndrome
Published: May 16, 2024
Diagnosing Guillain-Barré syndrome (GBS) is like solving a medical mystery. Doctors use a combination of your symptoms, physical exams, and specialized tests to piece together the puzzle.

The Spinal Tap: A Window to Your Nervous System
One key test for GBS is the spinal tap, also called a lumbar puncture. In this procedure, doctors take a small sample of the fluid surrounding your brain and spinal cord. In GBS, this fluid often shows high protein levels but normal cell counts - a clue called 'albuminocytologic dissociation'. This odd-sounding term is like a fingerprint for GBS.
Electrifying Evidence: Nerve Conduction Studies
Nerve conduction studies and electromyography (EMG) are like electrical detectives for your nerves and muscles. These tests measure how well and how fast electrical signals travel through your nerves. In GBS, these signals often slow down or get blocked. The pattern of these changes can help doctors determine the type and severity of GBS you have.
Blood Work: Ruling Out the Imposters
Blood tests are crucial in diagnosing GBS, but not because they directly confirm it. Instead, they help rule out other conditions that might mimic GBS. These could include vitamin deficiencies, toxin exposures, or other autoimmune disorders. In some cases, doctors might also look for specific antibodies associated with GBS.
