[13, 14], Diagnosis of plasma cell dyscrasias In approximately 95% of MS patients, two immunoglobulin G (IgG) oligoclonal bands (OCBs) are detectable exclusively in the cerebrospinal fluid (CSF). If the CSF protein concentration is >200 mg/dL, even high immunoglobulin production in the central nervous system can be obscured by the presence of plasma proteins. 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. The CSF oligoclonal band screen looks for these bands in your CSF. Their presence suggests inflammation of the central nervous system due to infection or another disease.

Get a step-by-step look, CSF cell count and differential are measured during cerebrospinal fluid analysis. To determine the diagnostic significance of serum OCBs 146 patients with serum OCBs were identified among 1874 patients with suspected neurological disorders (7.6%). If the test comes back positive for OCB levels, but a doctor cannot diagnose MS, they will likely order further testing to determine the underlying cause of the elevated OCB levels. brain herniation if a brain mass is present.

You may need to arrange to take the day of your test off. CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). Theyll send the CSF to a laboratory for analysis. 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. 2005 - 2023 WebMD LLC. These findings, however, are not specific for MS as CSF-specific IgG synthesis may also be found in patients with other neurologic diseases including infectious, inflammatory, cerebrovascular, and paraneoplastic disorders.

Tests that show an elevated level of OCBs indicate that a person might be living with MS. [9], Surveillance among patients with MGUS or smoldering (asymptomatic) multiple myeloma, Immunofixation of the urine and serum should be included in a battery of tests after 2-3 months following diagnosis of smoldering myeloma, then every 4-6 months for 1 year, and, finally, every 6-12 months if the results are stable. In this case, further tests will be necessary to determine the cause of any disease. In some cases, all the lanes are homogeneously darkened to the same degree. The site is secure.

Eric B Staros, MD Associate Professor of Pathology, St Louis University School of Medicine; Director of Clinical Laboratories, Director of Cytopathology, Department of Pathology, St Louis University Hospital When a narrow band with sharp borders can be identified, it implies the presence of a monoclonal protein (see image below). Oligoclonal bands CSF and Serum - myUpchar 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. Although an abnormal result supports a diagnosis of multiple sclerosis, it does not confirm the diagnosis. A local anaesthetic is used for the short procedure. -, Neurology. [9], In addition, immunofixation can be used to monitor therapy in plasma cell dyscrasias (ie, multiple myeloma and Waldenstrom macroglobulinemia). Philadelphia, PA, USA: Elsevier Churchill Livingstone; 2008. chapter 87. With IEF, oligoclonal bands may be detected while the total CSF IgG concentration is still within the normal range.
