Interpretive Data
Refer to Report
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
Note
If N-methyl-D-Aspartate Receptor Antibody is positive, then titer will be performed. Additional charges apply.
If CV2.1 Antibody IgG Screen by IFA is positive, then titer will be performed and Acetylcholine Receptor Binding Antibody will be added. Additional charges apply.
If Aquaporin-4 Receptor Antibody, IgG by IFA with Reflex to Titer, Serum is positive, then titer will be performed. 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, Yo, and Tr/DNER) IgG by Immunoblot will be performed. If the IFA screen is positive at 1:10 or greater, then a PCCA/ANNA antibodies titer and Neuronal Nuclear Antibodies (Hu, Ri, Yo, Tr/DNER) IgG by Immunoblot will be performed. Additional charges apply.
If Leucine-Rich, Glioma-Inactivated Protein 1 Antibody, IgG with Reflex to Titer, Serum is positive, then Leucine-Rich, Glioma-Inactivated Protein 1 Antibody Titer, IgG by IFA, Serum will be performed. Additional charges apply.
If Contactin-Associated Protein-2 Antibody, IgG with Reflex to Titer, Serum is positive, then Contactin-Associated Protein-2 Antibody Titer, IgG by IFA, Serum will be performed. Additional charges apply.
If Alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic Acid (AMPA) Receptor Antibody, IgG by IFA with Reflex to Titer, Serum is positive, then an Alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic Acid (AMPA) Receptor Antibody Titer, IgG, Serum will be performed. Additional charges apply.
If Gamma Aminobutyric Acid Receptor, Type B (GABA-BR) Antibody, IgG by IFA with Reflex to Titer, Serum is positive, then a Gamma Aminobutyric Acid Receptor, Type B (GABA-BR) Antibody Titer, IgG, Serum will be performed. Additional charges apply.
If Myelin Oligodendrocyte Glycoprotein (MOG) Antibody, IgG by IFA with Reflex to Titer, Serum is positive, then a Myelin Oligodendrocyte Glycoprotein (MOG) Antibody Titer, IgG will be performed. Additional charges apply.
If Dipeptidyl aminopeptidase-like protein 6 (DPPX) antibody, IgG by IFA with reflex to Titer, Serum is positive, then a Dipeptidyl aminopeptidase-like protein 6 (DPPX) antibody Titer, IgG will be performed. Additional charges apply.
