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.
CSF albumin is a measurement used to determine the levels of albumin in cerebrospinal fluid. [1] A closely related test, CSF total protein is a measurement used to determine the levels of protein in cerebrospinal fluid. [2] [3] It combines the albumin, IgG, and other proteins. It can be useful in distinguishing among causes of Meningitis.

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.
Due to the way it is produced, CSF has a lower chloride level than plasma, and a higher sodium level. [2] [6] CSF contains approximately 0.59% plasma proteins, or approximately 15 to 40 mg/dL, depending on sampling site. [7] In general, globular proteins and albumin are in lower concentration in ventricular CSF compared to lumbar or cisternal ...
CSF examination usually reveals normal pressure, cell count, and total protein content; however, CSF globulin is almost always elevated, constituting up to 20 to 60% of CSF protein. Serum and CSF contain elevated levels of measles virus antibodies. Anti-measles IgG appears to increase as the disease progresses.
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.
MOG-IgG is detected by means of so-called cell-based assays (CBA). CBA using live cells transfected with full-length human MOG and employing Fc-specific detection antibodies are the gold standard for anti-MOG antibody testing. [1] Serum is the specimen of choice; cerebrospinal fluid (CSF) analysis is less sensitive compared to serum testing. [1 ...
