Insert a needle with stylet at
the L3-L4 or L4-L5 or L5-S1 interspaced. When the subarachnoid space is
reached, remove the stylet and spinal fluid will appear in the needle hub.

Microbiology, Hematology, and Chemistry testing. The second tube will
generally go to Microbiology and the third to Hematology. Specimens for
viral culture are sent on ice.
