      Objective Blood-based biomarkers are attractive due to ease of sampling and standardized measurement technology, reducing obstacles to clinical implementation. The objective of this study was to evaluate a clinically ...
    • Efficacy of adrenal venous sampling is increased by point of care cortisol analysis 

      Viste, Kristin; Grytaas, Marianne Aardal; Jørstad, Melissa; Jøssang, Dag Eirik; Høyden, Eivind Næss; Fotland, Solveig Simmenes; Jensen, Dag Kjartan; Løvås, Kristian; Thordarson, Hrafnkell B; Almås, Bjørg; Mellgren, Gunnar (Peer reviewed; Journal article, 2013)
      Primary aldosteronism (PA) is a common cause of secondary hypertension and is caused by unilateral or bilateral adrenal disease. Treatment options depend on whether the disease is lateralized or not, which is preferably ...
    • Hormone references for ultrasound breast staging and endocrine profiling to detect female onset of puberty 

      Madsen, Andre; Bruserud, Ingvild Særvold; Bertelsen, Bjørn-Erik; Roelants, Mathieu; Oehme, Ninnie; Viste, Kristin; Bjerknes, Robert; Almås, Bjørg; Rosendahl, Karen; Mellgren, Gunnar; Sagen, Jørn V.; Juliusson, Petur Benedikt (Journal article; Peer reviewed, 2020)
      Context Application of ultrasound (US) to evaluate attainment and morphology of glandular tissue provides a new rationale for evaluating onset and progression of female puberty, but currently no hormone references complement ...
    • Multisteroid LC-MS/MS assay for glucocorticoids and androgens, and its application in Addison’s disease 

      Methlie, Paal; Hustad, Simon Steinar; Kellmann, Ralph; Almås, Bjørg; Moter-Erichsen, M; Husebye, ES; Løvås, Kristian (Peer reviewed; Journal article, 2013)
      Objective: Liquid chromatography–tandem mass spectrometry (LC–MS/MS) offers superior analytical specificity compared with immunoassays, but it is not available in many regions and hospitals due to expensive instrumentation ...
    • Primary Hyperparathyroidism Influences the Expression of Inflammatory and Metabolic Genes in Adipose Tissue 

      Christensen, Monika H. E.; Dankel, Simon N; Nordbø, Yngve; Varhaug, Jan Erik; Almås, Bjørg; Lien, Ernst Asbjørn; Mellgren, Gunnar (Peer reviewed; Journal article, 2011-06-17)
