      Aakre, Kristin Moberg; Ottesen, Anett Hellebø; Strand, Heidi; Faaren, Arne L.; Alaour, Bashir; Torsvik, Janniche; Sylte, Marit Sverresdotter; Marber, Michael; Christensen, Geir; Røsjø, Helge Rørvik; Omland, Torbjørn (Journal article, 2021)
      Background Secretoneurin is a novel prognostic biomarker that may predict mortality in heart failure and the occurrence of ventricular arrhythmias. This study reports the within subject variation (CVI), between subject ...
    • Estimating the within-subject (CVI) and between-subject (CVG) biological variation of serum tryptase 

      Skarbø, Birthe Rochlenge Skarbø; Vinnes, Erik Wilhelm; Wentzel-Larsen, Tore; Sylte, Marit Sverresdotter; Apelseth, Torunn Oveland (Journal article; Peer reviewed, 2021)
      Background Tryptase is used as a biomarker to support the diagnosis of anaphylaxis and hematologic diseases. In the event of a mast cell activation during anaphylaxis, a temporary increase in the concentration of tryptase ...
    • Estimation of Preanalytical Uncertainty in Clinical Chemistry 

      Sylte, Marit Sverresdotter (Doctoral thesis; Peer reviewed, 2013-05-27)
      Preanalytical uncertainty is attributable to variations in blood sample collection and sample handling before analysis. The aim of this study was to establish a modelling framework for estimating preanalytical uncertainty. ...
