• These data will be used to estimate deficiencies and toxicities of specific nutrients in the population and subgroups, to provide population reference data, and to estimate the contribution of diet, supplements, and other factors to serum levels of nutrients. (cdc.gov)
  • The expression levels and area under receiver operating characteristic curve values of plasma exosomal circRNAs and standard serum biomarkers were used to compare their diagnostic efficiency. (bvsalud.org)
  • However, the levels of standard serum biomarkers were similar between the two groups. (bvsalud.org)
  • However, immunoassays lack sensitivity to evaluate the lower concentrations of tobramycin for pharmacokinetic studies of for instance inhaled tobramycin. (betasciencepress-publishing.com)
  • However, a disadvantage of immunoassays for tobramycin is the limit of detection of 0.2 mg/L. Immunoassay methods are suitable to measure trough and peak concentrations of intravenously administered tobramycin, but they lack the sensitivity to evaluate lower concentrations of tobramycin for pharmacokinetic studies of, for instance, inhaled (dry powder) tobramycin.

  • Immunoassays are widely used for screening of biological samples . (scitechnol.com)
  • The adapted tobramycin immunoassay method has a linear range of 0.03 to 0.6 mg/L, which is comparable to liquid chromatography-mass spectrometry methods. (betasciencepress-publishing.com)
  • Noble metal nanoclusters (NMNCs) with sizes comparable to the Fermi wavelength of an electron exhibit fluorescence in correlation with the number of atoms in the cluster, which has potential applications in diverse areas, including electroluminescent display, solid-state lighting, and biomedical imaging.

  • The most frequently used method to quantify tobramycin in serum or plasma is with an immunoassay method. (betasciencepress-publishing.com)
  • The immunoassay method was validated with representative samples and has been implemented in routine analysis. (betasciencepress-publishing.com)
  • The objective of this project was to implement a LC-MS/MS method for screening of forensic ante- and post-mortem urine and whole blood samples that can replace the immunoassays. (scitechnol.com)
  • An enzyme-linked fluorescent immunoassay (ELFIA) method has been developed for the quantitative analytical determination of the herbicide active ingredient glyphosate in environmental matrices (surface water, soil, and plant tissues). (bvsalud.org)
  • The 96-well microplate-based competitive immunoassay method applies fluorescence signal detection in the concentration range of 0-100 ng/mL glyphosate. (bvsalud.org)
  • Clinical and biological characteristics (including T cell phenotype and function and plasma concentrations of 30 cytokines) and outcomes were compared. (biomedcentral.com)
  • However, LC-MS/MS is described as a promising technique that can overcome the limitations of immunoassays (such as their lack of selectivity). (scitechnol.com)
