Lyme CNS Infection IgG Screen, CSF

Lyme CNS Infection IgG, S

Reflex test: Lyme CNS Infection, IgG Ab Index

This test begins with IgG screening of the spinal fluid (CSF) specimen. If the screen is negative, no additional testing will be performed.

If the screen is positive, the paired CSF and serum specimens will be used to establish the antibody index. In order to establish the antibody index, the paired serum and CSF samples (collected within 24 hours of each other) are tested on the same run using quantitative assays to determine levels for the following analytes:

1. Anti-Borrelia species IgG levels in CSF and serum

2. Total IgG in CSF and serum

3. Albumin in CSF and serum

These additional tests are necessary in order to normalize the level of anti-Borrelia antibodies to total IgG and albumin in the CSF and establish the antibody index ratio of anti-Borrelia antibodies in CSF-to-serum. This testing is performed at an additional charge.
