This test does not include a pathology consult. If a pathology consultation is requested, PATHC / Pathology Consultation should be ordered and the appropriate FISH test will be ordered and performed at an additional charge.

This test includes a charge for application of the first probe set (2 FISH probes) and professional interpretation of results. Additional charges will be incurred for application of all reflex probes performed. Analysis charges will be incurred based on the number of cells analyzed per probe set. If no cells are available for analysis, no analysis charges will be incurred.

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.

If insufficient peripheral blood mononuclear cells (PBMCs) are isolated from the patient's sample due to low WBC counts or specimen volume received, selected dilutions or stimulants may not be tested at the discretion of the laboratory to ensure the most reliable results. Testing with 1 stimulant will always be performed. When adequate specimen is available for both stimulants to be tested, an additional test ID will be reflexed and billed separately.

Testing Algorithm:

If insufficient peripheral blood mononuclear cells (PBMC) are isolated from the patient's sample due to low white blood cell counts or specimen volume received, selected dilutions or stimulants may not be tested at the discretion of the laboratory to ensure the most reliable results. Testing with one stimulant will always be performed. When adequate specimen is available for both stimulants to be tested, an additional test ID will be performed at an additional charge.

This is a general urine screening test for a broad array of lysosomal storage (LSD) and related disorders. Not all LSDs are detectable by this method.


The first step in a diagnostic workup of an individual suspected of having a lysosomal storage disorder (LSD) includes urine analyses for metabolites associated with mucopolysaccharidoses, oligosaccharidoses, disorders of sulfatide degradation, and LSDs with characteristic urine profiles.

This test contains a combined analysis of ceramide trihexosides, mucopolysaccharides, oligosaccharides, and sulfatides. This combined analysis of these disease-specific markers allows for the identification of disorders that may not be picked up using any of the single tests alone.
