"Cerebrospinal fluid reference values for young infants undergoing lumbar puncture." WebA low CSF:blood glucose ratio. A CSF:blood glucose level of < 50% suggests possible meningitis. A CSF glucose level of ≤ 18 mg/dL or a CSF:blood glucose ratio of < 0.23 strongly suggests bacterial meningitis. However, changes in CSF glucose may lag 30 to 120 minutes behind changes in blood glucose. In acute bacterial meningitis, an …

WebOne of the most characteristic abnormalities of cerebrospinal fluid (CSF) in patients with bacterial and tuberculous meningitis is a decrease in its glucose content. This finding, first observed by Lichtheim, was initially attributed to utilization of glucose by the bacteria growing in the fluid This explanation, as many subsequent ones, has been abandoned in … WebThere was a weak correlation between blood and CSF glucose (r=0.07, P=0.007), and between blood and CSF lactate levels (r=0.58, P<0.001) on day 1, which were not influenced by insulin therapy. The presence of shock and low CSF glucose/lactate ratio were the only independent predictors of unfavorable outcome. WebApr 30, 2024 · Low CSF concentration of glucose (hypoglycorrhachia) in the absence of low blood sugar (hypoglycemia) is indicative of Glut1DS. Physicians should also measure lactate levels in the CSF. Lactate is low-normal or low in individuals with Glut1DS. These CSF findings are necessary but not sufficient to make the diagnosis of Glut1DS. blazers seattle
