|---|---|---|---|
| name | NMDAR IgG Ab [Titer] in Serum by Immunofluorescence | ||
| description | Semi-quanitative analysis of N-methyl-D-aspartate receptor IgG antibodies in serum to confirm the diagnosis of anti-NMDAR autoimmune encephalitis in conjunction with other laboratory and clinical findings. This test may also be used to monitor treatment response in individuals who are antibody positive. This term was created for, but not limited in use to, the EUROIMMUN Anti-Glutamate receptor (type NMDA) IFA assay. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | N-methyl-D-aspartate receptor Ab.IgG | ||
| property | Titr = Dilution Factor (Titer) | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser = Serum | ||
| scale | SemiQn | ||
| method | IF = Immune Fluorescence: Encompasses DFA, IFA, FA. Usually applies to cells and smears examined microscopically so that both the “where” and the “what” can be assessed, but can also be used on fluids in a way similar to ELISA. Does not include Cell binding assays (see CBA IFA above). | ||
