Webb26 aug. 2024 · The published reference values for CSF total protein concentrations suffer from two major drawbacks: (a) the values are method dependent (type of dye, precipitating agent, and calibrator); and (b) the age-related range often is too broad when applied to the steeply falling CSF protein concentrations in newborn infants ( Table 1 ) ( 3 ) ( 4 ) ( 5 ). WebbEven severe declines in total serum protein levels to below 4.0 gm/dl do not appreciably reduce CSF protein concentrations. 1 Common situations in which lumbar CSF protein values may fall below 20 mg/dl include normal infants and children less than 2 years of age, or in adult patients with acute water intoxication, untreated hyperthyroidism, …

Normal Values for Cerebrospinal Fluid in Neonates: A ... - PubMed
Webb24 juni 2024 · After performing a lumbar puncture, you finally get a cerebrospinal fluid (CSF) sample, and send it to the lab. The CSF has a pink hue, and your initial results show 8,300 red blood cells (RBCs) and 112 white blood cells (WBCs) in your sample. You are now faced with a diagnostic dilemma. WebbThere was a significant difference in CRP and increased total protein levels between infants with a positive bacterial compared to a positive viral CSF test result. CRP was significantly higher in neonates with bacterial CNS infection, as compared to those with a viral CNS infection ( P = .010). WebbCSF protein levels in the absence of meningitis are more variable; term infants have levels of < 100 mg/dL (1 g/L), whereas preterm infants have levels up to 150 mg/dL (1.5 g/L). CSF glucose levels in the absence of meningitis are > 75% of the serum value measured at the same time. These levels may be as low as 20 to 30 mg/dL (1.1 to 1.7 mmol/L). scotch 3m 8901
