Rapid, Noninvasive Diagnosis of Encephalitis by a Plasma-Based Next-Generation Sequencing Test.

Granulomatous amoebic encephalitis (GAE) caused by is a rare subacute infection with exceptionally high mortality. Diagnosis is typically made by brain biopsy or at autopsy. Detection of cell-free DNA by next-generation sequencing of plasma enabled rapid, noninvasive diagnosis in a case of amoebic encephalitis.
