Autoimmune encephalitis Panel , CSF

It is also recommended for new-onset seizures with MRI or CSF abnormalities.

An autoimmune encephalitis panel (CSF) requires a lumbar puncture (spinal tap).

A serum sample is often tested alongside, and you should rest afterward.

No, fasting is usually not required for an autoimmune encephalitis panel (CSF). You can eat and drink normally unless your doctor advises otherwise, for example if sedation is planned for the lumbar puncture. Inform your doctor about any blood thinners, and follow the hospital’s instructions.
