Clinical Info

Aiding in the diagnosis of neuroinvasive Lyme disease or neuroborreliosis due to Borrelia species associated 
with Lyme disease (eg, Borrelia burgdorferi, Borrelia garinii, Borrelia afzelli)
Requires CSF and Serum

Specimen Stability

CSF 11 days Refrigerated
35 days Frozen
Serum 11 days Refrigerated
35 days Frozen

Methodology

Enzyme-Linked Immunosorbent Assay (ELISA)
Testing Algorithm:
This test begins with IgG screening of the spinal fluid 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.
