CSF Glucose & Blood/Plasma Glucose

by menemsha menemsha (New) New

Can someone explain this to me.

i understand it is a ratio or a %, but would like to know how to interpret it.

I know that bacteria metabolizes glucose, so if a neonate had bacterial meningitis their CSG glucoe would be lower than their plasma glucose, but thats all.

What would normal CSF glucose & Blood glucose levels be What about in bacterial meningiits???



Specializes in NICU.

If I recall correctly, normal CSF glucose is about 60-70% of blood/serum. Best practice is to check a glucose just before the lumbar puncture. A markedly lower CSF glucose is an indicator of infection.
