Why do doctors take spinal fluid for analysis? For example, to diagnose multiple sclerosis.
This is a real question.

Idk, yrs ago Nana had Pseudotumor cerebri, a brain condition, and they had to pull spinal fluid out periodically because I was making too much of it and to test it.
Their tests revealed the diagnosis but not the cause. No one knows the cause.
That is a good question tho.
What do they get out of testing spinal fluid they can't get from their normal blood tests?

And what do they do with it? Do they take more than they need and utilize it in some other way?
It seems a pretty sacred fluid.

Idk, what I had they said was pretty rare. Idk if there are other diseases that require it.

Here's a link to a good explanatory of what they're looking for in spinal fluids from a spinal tap. They can get all kinds of info, from meningitis, to fungus, certain cancers, plus some specific disease markers could be found.
