Answer

A traumatic tap, of course, introduces WBCs and RBCs into the CSF (see Complications). An approximation of 1 WBC for every 1000 RBCs can be made, though a repeat tap may be preferable. Although no normal value for RBCs in the CSF is known, an occasional RBC may be incident to the tap itself.
