The Body Fluid Analysis Cerebrospinal Fluid (CSF) Test is a critical diagnostic procedure used to evaluate the fluid surrounding the brain and spinal cord. Performed via lumbar puncture, the analysis assesses physical appearance, measures glucose and protein levels, and conducts cell counts to detect infections (meningitis), inflammation, bleeding (subarachnoid hemorrhage), or neurological diseases like multiple sclerosis. Specialized tests can also identify specific proteins or malignant cells. Because CSF composition directly reflects the state of the central nervous system, this comprehensive analysis provides essential, often life-saving, information for the rapid diagnosis and management of complex neurological disorders.

An **Autoimmune Encephalitis Panel-2 CSF** is an advanced diagnostic panel performed on cerebrospinal fluid (CSF) to evaluate acute central nervous system inflammation caused by specific autoantibodies. By analyzing CSF directly—where neural antibody concentrations are often highest and most specific—this test screens for target antibodies targeting cell-surface and intracellular neuronal antigens, including NMDAR, LGI1, CASPR2, and GAD65.
This panel is vital for differentiating autoimmune-mediated neurological disorders from infectious or metabolic encephalopathies. Detecting these antibodies directly from CSF provides high diagnostic precision, enabling neurologists to rapidly initiate targeted immunotherapies, suppress brain inflammation, and optimize patient recovery.
