The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Note
If Striated Muscle Ab is detected, then a titer will be added. Additional charges apply.
If N-methyl-D-Aspartate Receptor Antibody is positive, then titer will be added. Additional charges apply.
If CV2.1 Antibody IgG Screen by IFA is positive, then a titer will be added. Additional charges apply.
If Aquaporin-4 Receptor Antibody IgG by ELISA is positive, then Aquaporin-4 Receptor Antibody, IgG by IFA will be added. If positive, then a titer will be added. Additional charges apply.
If Acetylcholine Receptor Binding Antibody result is greater than 0.4 nmol/L then Acetylcholine Receptor Modulating Antibody will be added. Additional charges apply.
Purkinje Cell (PCCA) antibody and Neuronal Nuclear (ANNA) antibody IgG are screened by IFA. If the IFA screen is indeterminate, then a Neuronal Nuclear Antibodies (Hu, Ri, and Yo) IgG by Immunoblot will be added.
