Generally we're looking for low glucose in the CSF, as that's a sign that bacteria may be in there. There's usually a ratio between CSF and serum glucose (CSF is about 60% of serum), so I'd wonder if your serum glucose was just on the higher end when you got the LP done due to your T1DM.
What does high glucose in a CSF mean?28, Female, T1D 14 years, 59 165 lbs. I have upper extremity weakness in my legs and arms, worsening over the last year. Cant walk up stairs, all my tests come back inconclusive including genetic testing and nerve (I mean literally I have had an ENTIRE work up- MRIs, X-rays, blood work, neurology, spine clinic, rheumatology) so Im left with getting a triple muscle biopsy and had a spinal tap today. The only result that came from that was high glucose CSF and I cant find anything about what that signifies versus the low glucose.ETA: additional test results just came back showing high wbc and rbc in the fluid.
