Age-specific reference values for CSF glucose, CSF/plasma glucose ratio and CSF lactate.

<p>Reference values are based on the 5^th to 95^th percentile values. The subgroups from the original data (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0042745#pone.0042745.s001" target="_blank">Tables S1</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0042745#pone.0042745.s002" target="_blank">S2</a>,<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0042745#pone.0042745.s003" target="_blank">S3</a>) were clustered into age groups which are commonly used in daily clinical practice (as used by MeSH, Pubmed).</p>*<p>Reference range after exclusion of CSF samples of patients with an unknown or abnormal plasma glucose (<3.0 mmol/L or >7.8 mmol/L) at the moment of lumbar puncture (only represented if >10% different from to the original value). Numbers between brackets represent values without correction for plasma glucose. ‡Reference range after exclusion of CSF samples with CSF lactate >3000 µmol/L (only represented if >10% different from the original value). Number between brackets represents upper limit without exclusion of CSF samples with CSF lactate >3000 µmol/L.
