• antithrombin
  • Apixaban was added to plasma from healthy subjects in the concentration range 0-1000 μg L(-1) , and analyses were performed with different reagents for activated partial thromboplastin time (APTT), prothrombin time (PT), antithrombin, protein C, and protein S. A lupus anticoagulant assay and an APTT assay with varying phospholipid concentrations were used to study the phospholipid dependence. (diva-portal.org)
  • protein
  • This study investigates the frequency of vitamin K deficiency among a convenience sample of children and adults with cholestatic liver disease by determining plasma levels of protein induced in vitamin K absence II (PIVKA-II), and assesses the relationship between PIVKA-II levels and markers of cholestasis, measured prothrombin time, and vitamin A, E and 25-hydroxyvitamin D levels.
