Stability of CSF metabolites measured by proton NMR. Academic Article uri icon

abstract

  • Analysis of cerebrospinal fluid (CSF) metabolites can provide data regarding CNS involvement in neurologic and psychiatric illness. However, there is lack of research into the effect of processing and storage of CSF specimens on the levels of metabolites analyzed. CSF specimens from 10 depressed patients were analyzed by proton NMR before and after 72 hours exposure to room temperature. No effect of exposure was found on myo-inositol, glucose, acetate, and alanine CSF levels and there was a substantial decrease of citrate (> 50%) and increase in lactate, glutamine, creatine, and creatinine levels.
