ENSKILD ANALYS 052
Dopamin-2 receptor (D2R) antikroppar
IndikationMisstanke om autoimmun encefalit.
MetodIndirekt immunofluorescens. Metoden är ännu inte validerad.
SvarAnges som negativ eller positiv med titer.
Kan testas i serum och likvor.
TolkningAutoantikroppar mot Dopamin-2-receptor (D2R) har rapporterats i ett fåtal fall av pediatrisk autoimmun encefalit. Typiska kliniska bilder hos barn är encefalit med dominerande rörelsestörningar, psykiatriska symptom, sömnstörningar, mutism och sänkt medvetande.
