1. A manometric reading is obtained (opening pressure) when the taps performed and the spinal fluid begins to flow. This reading can be diagnostic in some cases.
2. Gross appearance of the fluid must be recorded.
3. Cell count (lymphocytes, neutrophils, RBC's)
4. Protein content in mg/dl
5. Glucose level in mg/dl
6. Bacterial Culture, Gram stain and India Ink preparation
6. CRP, Lactic dehydrogenase
In addition to some specific antibodies detection depending on the primary diagnosis.
I would not let anybody but an anesthesiologist do the test.
