WebJan 1, 2015 · It has been reported that the levels of specific prostaglandin-d synthase (beta-trace) in CSF, which is mainly produced by leptomeninges and glia, undergo circadian changes (Jordan et al. 2004). While the lumbar CSF is most prevalent in the first CSF portion, more ventricular CSF will be present when an increasing volume is sampled. WebMay 12, 2011 · Beta-trace protein test. Another method useful for the diagnosis of CSF fistulas is nephelometric determination of beta-trace protein (betaTP) level. Beta-trace protein belongs to the most abundant CSF proteins, while it is not present in tear fluid [25]. The nephelometric assay is based on a latex particle-enhanced immunologic assay using ...
