alpha1-globulin ( 1 -globulin). [14], Mass spectrometry is sometimes employed in place of immunofixation because of the latters limitations, such as in the detection of low-level disease. Multiple sclerosis is a CNS disorder in which the immune system damages myelin (a protective sheath around nerves), the nerves and the cells that produce myelin. Finally, intrathecal humoral immune response can also occur, although rarely, in patients with peripheral neuropathies, particularly in those of inflammatory origin, as a possible consequence of blood-spinal nerve root barrier (BSNRB) damage. Oligoclonal bands may be observed in the following conditions: Multiple sclerosis Viral and bacterial meningitis HIV (AIDS) Cerebral infarction (death of brain tissue due to insufficient blood flow) Guillain-Barr syndrome (an autoimmune condition that affects the nerves) Neurosyphilis Learn how this disease affects the nervous system. The presence of oligoclonal bands in CSF but not in the serum, given their intrathecal production, is helpful in the diagnosis of multiple sclerosis. [ 1] Serum or urine immunofixation negative for a monoclonal protein or a polyclonal pattern is considered to be normal. 1998 Jul;61(7):375-81.

The diagnostic process will also involve the doctor: If elevated OCB levels are present but a person does not fit the criteria for MS, a doctor will likely continue to search for the underlying cause. Your central nervous system contains a clear liquid called cerebrospinal fluid (CSF). Anastasios Dimou, MD Resident Physician, Department of Internal Medicine, Albert Einstein Medical CenterDisclosure: Nothing to disclose. Finally, when several bands with sharp borders are seen after immunofixation in cerebrospinal fluid (CSF) but not in serum, the result is reported as positive for oligoclonal bands. The patient urinates each time into a clean dry vessel and then pours the urine in the plastic container, which is kept at a cold temperature (eg, in the refrigerator).

An EEG is a test that measures your brain waves and helps detect abnormal brain activity. [3], Waldenstrom macroglobulinemia Damage to your spinal cord if you move during the procedure, Cerebral infarction (death of brain tissue due to insufficient blood flow), Idiopathic polyneuritis (inflammation of multiple nerves without an obvious cause), Cryptococcal meningitis (infection in the brain due to Cryptococcus fungus), Subacute sclerosing panencephalitis (a slowly progressive neurological disorder caused by measles virus), Progressive rubella panencephalitis (a neurological condition caused by rubella virus). The presence of oligoclonal bands (OCBs) of immunoglobulin G (IgG) in CSF provides evidence for the occurrence of a humoral immune response, but it is not always appreciated that the oligoclonal IgG may have originated in the serum. An official website of the United States government. OCBs can also be present in other central nervous system (CNS) disorders, including antibody-mediated, inflammatory, infectious, and neurodegenerative conditions, as well as in both chronic and early disease stages, suggesting the occurrence of primary or concomitant immune-mediated processes. CSF immunofixation that does not reveal oligoclonal bands is also considered normal. 8600 Rockville Pike PMC A normal result includes a darker immunoglobulin G (IgG) lane, a lighter immunoglobulin A (IgA), an absent immunoglobulin M (IgM), and a denser kappa compared to lambda lane, with ratio of 2:1. The separated immunoglobulins (Ig) are visualized by an IgG immunoblot, and OCBs that are present in the CSF and not in the serum are reported. J Neurol Neurosurg Psychiatry. These bands in the CSF pattern are produced by a limited number of immunocompetent cell clones, each producing IgG with its own specificity. Learn more.

Serum electrophoresis separates proteins into 5 different bands: Albumin, and Prealbumin. Oligoclonal band investigations requires both serum and cerebral spinal fluid (CSF). The results of an EEG can be used to rule out or confirm. 135:1048-51. Isoelectric focusing (IEF) on agarose gels followed by immunoblotting is the technique recommended for OCB detection, analyzing paired undiluted CSF and serum samples. Red top tube for the collection of serum used. Oligoclonal Bands . Oligoclonal bands may be observed in the following conditions: Disclaimer: All results must be clinically correlated with the patients complaints to make a complete and accurate diagnosis. Andersson M, Alvarez-Cermeno J, Bernardi G, et al: Cerebrospinal fluid in the diagnosis of multiple sclerosis: a consensus report. government site. [10], Primary screening for plasma cell dyscrasias, No studies have addressed the role of serum or urine immunofixation in screening of the general population for multiple myeloma and related disorders. CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). Consensus recommendations for standard investigative workup: report of the International Myeloma Workshop Consensus Panel. Diagnoses in the second group of patients, with unique CSF OCBs in addition to serum OCBs, resembled those among patients with CSF OCBs alone. The presence of 2 or more unique CSF oligoclonal bands was reintroduced as one of the diagnostic criteria for MS in the 2017 revised McDonald criteria. A serum sample is taken at the time of the lumbar puncture as oligoclonal bands may be present in CSF alone or CSF and blood.

In a normal result, the lanes are broad and there is a gradual and smooth reduction in the color density toward the edges of the lane with no narrow dense band with sharp borders identified within the lane. Their presence suggests inflammation of the central nervous system due to infection or another disease. In most cases in which a monoclonal protein is present, it shows as a narrow band at the IgG lane in combination with a monoclonal band at the kappa or lambda lane. The speed of movement is dictated by their charge. Lahuerta JJ, Jimenez-Ubieto A, Paiva B, et al. This gown gives the person conducting the test easy access to your spine.
