If this protective barrier disrupts may result in a change in the normal level or type of constituents of CSF. If this protective barrier disrupts may result in a change in the normal level or type of constituents of CSF. Because CSF surrounds the brain and spinal cord, testing a sample of CSF can be very valuable in diagnosing a variety of conditions affecting the central nervous system (CNS)..

CSF usually collected in three sterile tubes Label 1 / Tube 1 – used for chemical and serologic test ( tubes are frozen) Label 2 / Tube 2 – used for microbiology lab ( room temp.) Label 3 / Tube 3 – used for hematology (cell count) ( refrigerated)

(Cell count and differential)—any cells that may be present are counted and identified by cell type under a microscope.
