CSF can be tested for the diagnosis of a variety of [neurologic disease]?s. Usually, it is obtained by a procedure called [lumbar puncture]? in an attempt to count the cells in the fluid and to detect the levels of protein and glucose. These parameters alone may be extremely beneficial in the diagnosis of central nervous system infections (especially meningitis?) and [subarachnoid hemorrhage]?. Moreover, a CSF culture examination may yield the micro-organism? that has caused the infection. By using more sophisticated methods as the detection of the [oligoclonal bands]?, an ongoing inflammatory condition (e.g.Multiple Sclerosis) can be recognized. Lumbar puncture can also be performed to measure the intracranial pressure, which is increased in a condition known as hydrocephalus?.
