What conditions show oligoclonal bands in CSF?

Oligoclonal bands in CSF have been reported in cases of neurosyphilis, acute bacterial or viral meningitis, progressive multifocal leukoencephalopathy, subacute sclerosing panencephalitis, progressive rubella panencephalitis, polyneuritis, optic neuritis, trypanosomiasis, and other infectious or autoimmune diseases.

Is it normal to have oligoclonal bands in CSF?

The determination of oligoclonal bands is a useful aid in the diagnosis of multiple sclerosis, subacute sclerosing panencephalitis, and herpes simplex encephalitis. The presence of oligoclonal bands indicates an immunological response but is not diagnostic for a particular condition.

How many oligoclonal bands indicate MS?

NASHVILLE—Patients with multiple sclerosis (MS) and 10 or more oligoclonal bands (OCBs) in CSF may have significantly more clinical and radiographic relapses and clinical progression during short-term follow-up than those who have fewer OCBs, according to data described at the 2018 CMSC Annual Meeting.

How many oligoclonal bands are there in CSF?

Oligoclonal bands are defined as at least two bands seen in the CSF with no corresponding band present in the serum. Thus, it is crucial to perform CSF and serum electrophoresis simultaneously, preferably in adjacent lanes. Oligoclonal bands may be found in 95% or more of patients with clinically definite MS [17].

Can you have oligoclonal bands and not have MS?

The presence of oligoclonal bands in clinically isolated syndromes is an independent risk factor for developing multiple sclerosis and has been largely excluded from the more recent multiple sclerosis diagnostic criteria.

How do you read an oligoclonal band?

Interpretation. When the oligoclonal band assay detects 2 or more unique IgG bands in the cerebrospinal fluid (CSF), the result is positive. CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands).

Does everyone have oligoclonal bands?

Oligoclonal bands are an important indicator in the diagnosis of multiple sclerosis. Up to 95% of all patients with multiple sclerosis have permanently observable oligoclonal bands at least for those with European ancestry.

What does matching oligoclonal bands mean?

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. If similar bands aren’t present in your blood, you may have multiple sclerosis (MS).

Does oligoclonal bands always mean MS?

What does 6 oligoclonal bands mean?

Oligoclonal bands are proteins called immunoglobulins. The presence of these proteins indicates inflammation of the central nervous system. The presence of oligoclonal bands may point to a diagnosis of multiple sclerosis.

Can you still have MS without oligoclonal bands?

In multiple sclerosis (MS) more than 95% of the patients have positive oligoclonal bands (OCB) in the cerebrospinal fluid (CSF). Previous studies have reported differences between patients with and without OCB mainly with regard to clinical parameters such as age, gender, disease duration, and clinical severity.

What are O bands in MS?
