Voltage-gated potassium channel blanket testing in first-episode psychosis: Diagnostic nihilism?

CONCLUSION: Voltage-gated potassium channel antibody-associated limbic encephalitis was rare, and always associated with high antibody titres. Low-positive titres were not associated with the development of encephalitis over a long period of follow-up. The value of universal voltage-gated potassium channel antibody screening is unclear, and further prospective studies in first-episode psychosis populations are required.
