Neuronal Cell Antibodies, Quantitative, CSF
Also known as: NEURON CSF
Use
The Neuronal Cell Antibodies, Quantitative test in cerebrospinal fluid (CSF) is used to help diagnose neuropsychiatric systemic lupus erythematosus (SLE). Elevated levels of anti-neuronal cell antibodies in serum or CSF have been associated with neuropsychiatric manifestations of SLE, and this test assists in determining these elevated levels.
