Cerebrospinal Fluid Analysis

Another test you may not be familiar with, but might have to undergo is a Cerebrospinal fluid analysis. Cerebrospinal fluid is the liquid located surrounding the brain and spinal cord. The neurologist will carry out a lumbar puncture and use a needle to withdraw some of this fluid for analysis. He or she will investigate if the fluid is normal, by looking at components such as the number of cells present, or the level of protein and glucose inside the CSF.
