type 3, oligoclonal bands in CSF and serum with additional bands in CSF; type 4, identical oligoclonal bands in CSF and serum, type 5, monoclonal bands in CSF and serum, type 6, presence of a single band limited to the CSF. Type 2 and 3 indicate intrathecal synthesis, and the rest are considered as negative results (No MS).
[55] [56] The charitable organization Group B Strep Support has published a list of hospitals in the UK that offer the detection of GBS using the enrichment broth culture method (enrichment culture medium, ECM). [72] This test is also available privately from around £35 per test for a home-testing pack, and it is offered by private clinics. [72]
Pandy's test (or Pandy's reaction) is done on the CSF (cerebrospinal fluid) to detect the elevated levels of proteins (mainly globulins). This test is named after the Hungarian neurologist , Pándy Kálmán (1868–1945) who developed this test in the year 1910.

[3] Typically, both sides of the body are involved, and the initial symptoms are changes in sensation or pain often in the back along with muscle weakness, beginning in the feet and hands, often spreading to the arms and upper body.

GBS colonies can additionally be identified tentatively after their appearance in chromogenic agar media, nevertheless GBS-like colonies that develop in chromogenic media should be confirmed as GBS using additional reliable tests (e.g.latex agglutination or the CAMP test) to avoid potential mis-identification.
Anti-GD3 antibodies have been found in association with specific forms of Guillain–Barré syndrome. In vivo studies of isolated anti-GM1 and GD3 antibodies indicate the antibodies can interfere with motor neuron function. [2]
Lumbar puncture ("spinal tap") is the procedure to obtain CSF. The VDRL test of the CSF is a common test for making a diagnosis of neurosyphilis. A positive VDRL test in the presence of neurological symptoms is sufficient to confirm a diagnosis of neurosyphilis. [4] However, a negative VDRL result does not rule out neurosyphilis.
Most cases occur due to inadequate antenatal screening and treatment during pregnancy. [8] The baby is highly infectious if the rash and snuffles are present. [4] The disease may be suspected from tests on the mother; blood tests and ultrasound. [9] Tests on the baby may include blood tests, CSF analysis and medical imaging. [10]
