Test ID: MSP3    
Multiple Sclerosis (MS) Profile, Serum and Spinal Fluid

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Kappa free light chain will be performed by nephelometry on all samples. When kappa free light chain results are 0.0600 mg/dL or more, the oligoclonal banding tests will be performed at an additional charge. If the time of testing exceeds the specimen stability for oligoclonal banding tests only kappa free light chain will be performed. Kappa free light chain will only be performed up to specimen stability.
