Oligoclonal Banding, CSF (Albumin/IgG CSF)
Test Name Oligoclonal Banding, CSF (Albumin/IgG CSF)
Specimen Type / Requirements Container Type = Sterile, screw-capped transport tube or CSF tube. Preferred volume to collect CSF: 1mL Preferred volume to collect Serum:: 1mL Minimum Testing Volume to collect: 0.5 mL CSF Min volume for serum specimen: 0.5 mL Neonate volume to collect: 0.5 mL CSF Tube 1: Cell count Tube 2: Glucose and protein, Oligoclonal Banding Tube 3: Gram stain and culture (C+S) or Virology Tube 4: Cell count/Flow Cytometry/cytology
Specimen Handling Collection Instructions: Collect CSF and a minimum of 1 mL serum. It is essential for interpretation of results to submit both specimens at the same time, but a serum sample of +/- 21 days of the spinal tap is acceptable as long as no treatment was started. Analyze specimens fresh whenever possible Laboratory Staff Instructions: Enter date and time collection in the LIS. Specify sample number in order comment. Stability: Stable for 1 day at 15-25°C, 3 weeks at 2-8°C and for 6 months at -20°C or lower temperature. Transportation: Send to lab as soon as possible. Do not send via the pneumatic tube system.
