I’m not entirely sure what you mean by "blood and blood count being elevated"—I’m guessing you mean "abnormal." Basically, yes, bacterial inflammation usually shows up more clearly in blood work (think high WBC, elevated CRP, ESR...). But look, nothing in medicine is ever 100%. You can't just rely on a standard blood panel to confirm suspected bacterial meningitis; that's exactly why they check the spinal fluid. To put it simply, the brain is isolated from the bloodstream by a barrier, acting like a relatively closed system. The CSF is in direct contact with the brain and its linings, so it shows specific lab changes during the process that help nail down a diagnosis. If we could prove bacterial meningitis through a simple blood draw, nobody would bother with lumbar punctures. Obviously, the doctor managing the case has the best grasp of the clinical picture and medical history, so if they ordered an LP, they probably have their reasons. Besides, it’s not like it’s some terrifying procedure.
Seems to me like this is just fear of the test itself. It’s not nearly as scary as people make it out to be. If the doctor thinks it’s necessary—just get it done.
