Compliance Category

Laboratory Developed Test (LDT)

Note

If CV2 antibody IgG is positive, then titer will be added. Additional charges apply.
PCCA/ANNA antibody IgG is 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 DPPX antibody IgG by IFA is positive, then titer will be added. Additional charges apply.
If AQP4/NMO antibody IgG by IFA is positive, then titer will be added. Additional charges apply.
If mGluR1 antibody IgG by IFA is positive, then titer will be added. Additional charges apply.
If MOG antibody IgG by IFA is positive, then titer will be added. Additional charges apply.
If GABA-BR antibody IgG by IFA is positive, then titer will be added. Additional charges apply.
