Toxoplasma gondii IgG Antibody, ELISA (CSF)
Also known as: TGONDI IGG
Use
The Toxoplasma gondii IgG Antibody, ELISA (CSF) test is used to diagnose central nervous system infections by demonstrating the presence of intrathecally-produced specific antibodies. This test may be particularly useful in patients suspected of having CNS toxoplasmosis, although it has limited utility for routine clinical use due to low sensitivity in serology for detecting CNS infections.
Special Instructions
This test is performed by a non-ARUP laboratory, specifically Quest Diagnostics Nichols Institute. Ensure separate specimens are submitted for multiple tests ordered as this test is not performed directly by ARUP.
Limitations
The Toxoplasma gondii IgG Antibody ELISA test is limited in its clinical utility due to the low sensitivity of serology for CNS infections. Low antibody levels in CSF, passive transfer of antibodies from blood, and contamination via bloody taps can complicate interpretation of results.
