Special Processing:  
Comments: This test is available to LHSC Neurologists only and accepted from referred in locations.
A single autoantibody test is not diagnostic and should not be used to determine course of treatment.
The test result must be evaluated with consideration of clinical presentation, patient history and other laboratory tests.
Method of Analysis: Recombinant Cell-based Immunofluorescence Assay (IFA)
Critical Information Required: Testing for AQP4 and MOG antibodies may be more sensitive in serum than in CSF. CSF testing should only be considered in patients receiving acute immunotherapy such as plasma exchange, and should be accompanied by a serum sample.
Storage & Shipment: The samples can be stored for up to 14 days at temperatures of 2-8oC. For longer storage, store at -20oC.
Avoid freeze/thaw cycles.
