|Lyme Disease Antibody Index:|
|Control Antibody Index:|
The Borrelia burgdorferi antibody index is used as an aid for the diagnosis of neuroborreliosis. An increased Borrelia burgdorferi antibody index (> 1.2). Accompanied by a control antibody index of less than 1.0 and an albumin ratio of less than 0.0078 is strong evidence for inrathecal synthesis of organism-specific antibody, and thus CNS involvement by B. burgdorferi. Elevation of either the control antibody index, the albumn ratio, or both may indicate leakage of antibody across the blood-brain barrier which may falsely elevate the B. burgdorferi antibody index.
