Abstract
(EN)
Provided are a detection material, a preparation method and an application of an anti-NMDAR autoantibody in human body fluid, NMDAR antigen is coated on a carrier film to prepare an anti-NMDAR receptor detection material, a specific NMDAR antibody in human serum and cerebrospinal fluid can bond with the antigen, an alkaline phosphatase substrate-ligand reaction is carried out for color development, a sealing material is added to the color reaction, and it can be directly judged whether the NMDAR antibody is contained in the detection sample by visual observation. The method has the advantages of high sensitivity, simple and convenient operation, rapid detection and the like, and is beneficial to the recognition and diagnosis of anti-NMDAR receptor encephalitis.
