| Synonyms:
| MS Profile |
| Specimen: | Blood: (1) SST (serum separator) or Red (no preservative) top vacutainer tube.
CSF: CSF in a sterile CSF tube.
Collect both specimens at the same time. |
| Volume: | 2 mL serum (2 tubes) and 2.5 mL CSF (2 tubes) |
| Minimum Volume: | 1.0 mL serum and 1.0 mL CSF |
| Collection: | If tube other than an SST is collected, transfer serum to a tightly capped plastic aliquot tube within 2 hours of collection.
Submit 2 tubes of serum. 1st tube=1.5 mL and 2nd tube= 0.5 mL. Refrigerate both serum tubes.
Submit 2 tubes of CSF. Centrifuge CSF at 2000xg at refrigerated temperature for five minutes. 1st tube= 1 mL (refrigerated) and 2nd tube= 1.5 mL (frozen). |
| Rejection Criteria: | Plasma instead of serum specimen; serum and CSF not collected within eight hours of each other; CSF not received frozen; improper labeling. |
| Reference Range: | See report |
| Methodology: | MBP: enzyme-linked immunosorbent assay (ELISA); oligoclonal banding: IEF; CSF IgG, CSF albumin, and serum IgG: immunologic; serum albumin: spectrophotometry; synthesis rate, ratio, and index by calculation |
| Test Use: | Adjunct in aiding clinical diagnosis of multiple sclerosis. |
| Additional Information: | No Additional Information Listed |
| Testing Includes: | IgG and albumin quantitation in both serum and spinal fluid samples; CSF IgG:CSF albumin ratio; CSF IgG index; CSF IgG synthesis rate; myelin basic protein (CSF); oligoclonal banding.
