Laboratory assay overview

The Lyme disease antibody index is used as an aid for diagnosing neuroborreliosis. The assay requires paired serum and CSF. A result set of lyme disease antibody index >1.2, control antibody index <1.0, and albumin ratio <0.0078 provides strong evidence of intrathecal synthesis of b. Burgdorferi antibodies and supports the diagnosis of neuroborreliosis.

Quest Diagnostics population reference ranges

Quest Diagnostics calculates these statistical intervals for this specific assay and demographic group, not as universal optimal targets.

Population	Range
≤1.0	Negative
1.1-1.2	Equivocal
≥1.3	Positive
Control Antibody Index	≤1.0
Albumin Ratio	<0.0078

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
