Abstract
A blood collection device comprising formed additive particles. The additive particles are an improvement over available additive formulations that are powder blended in that the components of the additive particles of the present invention are in each formed particle. The formed additive particles comprise a fluoride salt and an ethylenediaminetetraacetate salt or a heparin salt to consistently minimize glycolysis and coagulation of a blood specimen with low hemolysis.
