Term Description

Semi-quanitative analysis of N-methyl-D-aspartate receptor IgG antibodies in CSF specimens 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.

Part Description

LP200573-6   N-methyl-D-aspartate receptor
N-methyl-D-Aspartate receptor (NMDAR) is a type of glutamate receptor found in nerve cells. It plays a key role in controlling synaptic plasticity and memory function. PMID: 19605837 Anti-NMDAR IgG antibodies are found in a subset of patients with autoimmune limbic encephalitis, which progresses from symptoms such as psychosis, memory deficits, seizures, and language disintegration into a state of unresponsiveness with catatonic features and breathing instability. The disorder predominantly affects children and young adults and may occur with or without tumor association. Decreasing antibody levels may be associated with therapeutic response.
