Ans. A. Evaluating cognition in NPHEvaluating cognition in NPH. The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH).The test involves removing 30mL of cerebrospinal fluid (CSF) through a lumbar puncture, after which cognitive function is clinically reassessed.
