What is the normal total volume range for cerebrospinal fluid?

The normal total volume range for cerebrospinal fluid (CSF) is indeed 90-200 mL. CSF is a clear, colorless liquid that circulates through the brain and spinal cord, providing essential protection, nourishment, and waste removal for the central nervous system.

The specified volume range reflects the typical amount of CSF present in an adult individual. It’s important to note that variations outside this range can indicate potential medical issues, such as conditions involving intracranial pressure or infections that may alter the production or absorption of CSF. Therefore, understanding this volume range is crucial for laboratory and clinical evaluations involving CSF analysis.
