Overview
Guillain-Barré syndrome (GBS) is usually diagnosed clinically. Lab tests are done to exclude other diagnosis and assess prognosis. The lab tests ordered are basic labs (CBC, ESR), lumbar puncture (GBS has characteristic albuminocytological dissociation), serological markers
Laboratory test
Routine labs
- Complete blood count + ESR (increased in inflammatory process)
- Serum electrolytes
- Liver function test
- Creatinine kinase increased in inflammation and myopathies
- Stool culture for campylobacter jejuni (less frequent)
Serology
- Less frequently done for campylobacter jejuni, CMV, EBV, HSV, HIV and mycoplasma pneumonia.
- Autoantibodies are only measured in case the diagnosis of GBS is uncertain. Antibodies to glycolipids, anti GM1 antibodies and Anti-GQ1b are increased.
Peripheral neuropathy panel
A panel of tests can be ordered in cases of diagnostic uncertainty with other peripheral neuropathies
- Thyroid profile (to rule out thyroid neuropathies)
- Erythrocyte sedimentation rate (ESR)increased in inflammatory process
- Rheumatology profiles
- Hemoglobin A1c for diabetic neuropathy
- Immunoelectrophoresis for serum protein (multiple myeloma)
