Bedside cerebrospinal fluid glucose analysis.
We studied the reliability and accuracy of a two-minute reagent strip (Chemstrip bG) and hand-held autoanalyzer (Accu-Chek IIR) for determining cerebrospinal fluid glucose. We found that both bedside methods were highly reliable (r = 0.93, Chemstrip bG: r = 0.95, Accu-Chek II) and were very accurate (89.7% and 96.6% accurate at +/- 15 and 20 mg/dL, respectively, for the Chemstrip bG: 91.7% and 95.8% accurate at +/- 15 and 20 mg/dL, respectively, for the Accu-Chek II) over a wide range of glucose values in 237 determinations. There was no significant difference between the two bedside methods. We conclude that these two methods of bedside glucose estimation are both highly reliable and accurate and could be used to quickly determine patients' cerebrospinal fluid glucose values.
