The lumbar puncture wasn't as bad as I was expecting, although I was surprised how hard he had to push to get that needle in. Before he started, I asked the (nurse? nurse practitioner?), "Will it hurt like bloody hell? Please tell me the truth!" It wasn't pleasant, but it didn't hurt much. Anyway, the results: OLIGOCLONAL BANDS no bands CELL COUNT/DIFF WBC-CSF 0.0 0-5 RBC-CSF 27 0 HIGH BODY FLUID DIFF SEGS 4 LYMPH 7 MONONUCLEAR 10 Glucose (CSF) 54 40-80 T. Protein, CSF 37 15-45 Gram Stain Final no bacteria seen CSF Culture no growth 48 hrs RPR nonreactive The tests were ordered by a neurologist; my impression is he is looking for signs of MS. I was hoping there would've been many more tests done, especially for viruses. I'm guessing the high Red Blood Cell indicates a 'tramatic tap', perhaps? I don't know what SEGS and MONONUCLEAR refer to, or why there are no reference ranges. According to Lab Tests Online, RPR is a quick test for syphylis that gives false positives for various other problems. Would this be a quick and dirty way to test for the presence of viruses?
