Guillain-Barré syndrome is diagnosed through a neurological evaluation and specific tests ordered by a specialist. If a GP suspects you have Guillain-Barré syndrome, they will refer you to a neurologist, a specialist in nerve conditions, for diagnosis and treatment.
Diagnostic Tests for Guillain-Barré Syndrome
The diagnosis typically involves the following tests:
-
Neurological Examination: A thorough assessment of your reflexes, muscle strength, and sensory functions is performed.
-
Electrical Test of Nerves and Muscles: According to the provided information, an "electrical test of your nerves and muscles" is conducted. This likely refers to tests such as:
-
Nerve Conduction Studies (NCS): These tests measure the speed and strength of electrical signals traveling through your nerves. They can identify nerve damage, a hallmark of Guillain-Barré Syndrome.
-
Electromyography (EMG): This test assesses the electrical activity of your muscles. It can reveal muscle weakness or dysfunction resulting from nerve damage.
-
-
Breathing Test (Spirometry): The provided information includes a breathing test as part of the tests that might be performed.
-
Other Possible Tests: While not explicitly mentioned in the provided information, other tests may be performed to rule out other conditions or confirm the diagnosis:
- Lumbar Puncture (Spinal Tap): A sample of cerebrospinal fluid (CSF) is collected and analyzed. In Guillain-Barré syndrome, the CSF often shows elevated protein levels without a corresponding increase in white blood cell count.
