Tests to ask for alongside lumbar puncture?

[Guest guest]

Henry is having an MRI under IV sedation just before Christmas. At the same time

they will be doing a lumbar puncture to test his pyridoxine levels (I think

that's what it is - we have had to withdraw his B6 ahead of the test). As he is

going through all this unpleasant experience I am wondering if I should try and

get any other testing done at the same time.

Could I ask them to keep a sample of CSF for later testing - or is this

pointless because the sample would degrade in any case? Am I right that blood

samples wouldn't be much use because he drugs used to sedate him would make

results generally unreliable?

It is not possible in general to get a blood samplebecaseu he would fight like

crazy.

I don't want to be thinking some time later " Oh if only we'd done that test

while he was sedated " , though.

Any suggestions would be welcome, please.

Thanks,

Margaret

Maybe an EEG if possible if it might be relevant, these are usually better done

when asleep.
