The date and time of the current lumbar puncture Turnaround times Relevant clinical details including the reason for the investigation and the date of any previous lumbar puncture (if within the last month). A minimum of 0.5 mL blood taken into a narrow gold top tube ( or rust top for the Acute Unit) (1 mL of CSF is approximately equal to 25 drops from the Luer connector of the needle).Ģ. A minimum of 0.5 mL of CSF collected into a plain 30 mL Universal If other CSF investigations are required please check the CSF Sample Requirements webpage for further detailsġ.Blood must be collected on the same day as the lumbar puncture (and within an absolute maximum of 14 days of lumbar puncture), for samples to be processed).CSF with simultaneous blood sample (1 and 2 below).The finding of oligoclonal bands is not specific, as they may also be found in Guillain-Barré syndrome, CNS infections (including neurosyphilis and HIV infection), after cerebrovascular accidents and in other CNS disorders.We identified only 4/118 (3.4 95 CI 1.1 to 9.0) patients with MOG-IgG exclusively detected in the CSF with semi-quantitative visually assessed CBA scores (1, 1, 2 and 4 out of 4, samples scoring 1 to 1.5 are. The presence of oligoclonal bands in CSF, but not serum, is indicative of local immunoglobulin synthesis and occurs most commonly in multiple sclerosis (>90% of patients) and subacute sclerosing panencephalitis (SSPE). either serum or CSF of which 66/118 (55.9) were only positive in the serum and 48/118 (40.7) were positive in both compartments.Oligoclonal band investigations requires both serum and cerebral spinal fluid (CSF).Saadeh R, Pittock S, Bryant S, et al: CSF kappa free light chains as a potential quantitative alternative to oligoclonal bands in multiple sclerosis. Gurtner KM, Shosha E, Bryant SC, et al: CSF free light chain identification of demyelinating disease: comparison with oligoclonal banding and other CSF indexes.
