type 1, no bands in CSF and serum; type 2, oligoclonal IgG bands in CSF, 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.
Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases , such as pseudomigraine, Susac's syndrome, and encephalitis.
Cerebral spinal fluid (CSF) shows normal protein, glucose, white blood cell, and immunoglobulin G (IgG) levels, but there are weak oligoclonal bands, which are absent in the blood serum. Marked changes in circadian serum levels of neurohormones and increased levels of peripheral neurotransmitters were also observed.
Very high levels of protein may indicate tuberculous meningitis or spinal block. [citation needed] IgG synthetic rate is calculated from measured IgG and total protein levels; it is elevated in immune disorders such as multiple sclerosis, transverse myelitis, and neuromyelitis optica of Devic.

Immunoglobulin therapy is the use of a mixture of antibodies (normal human immunoglobulin) to treat several health conditions. [13] [14] These conditions include primary immunodeficiency, immune thrombocytopenic purpura, chronic inflammatory demyelinating polyneuropathy, Kawasaki disease, certain cases of HIV/AIDS and measles, Guillain–Barré syndrome, and certain other infections when a ...
The water-accessible surface area of an IgG antibody. Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation. [1] IgG molecules are created and released by plasma B cells. Each IgG antibody has two paratopes.
[1] [8] There are also various biological indicators, such as elevated cerebral spinal fluid proteins and elevated IgM monoclonal levels. These can also be tested either by drawing serum from a patient or by drawing spinal fluid from a spinal tap and testing using an assay or blot. [1]
