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.

Abstract: The present invention is a specimen collection container assembly comprising an inner tube within an outer tube wherein the external dimensions of the inner tube are less than the external dimensions of the outer tube and the internal volume of the inner tube is less than the internal volume of the outer tube. The assembly of the present invention provides a means for adapting a full-draw or standard-sized blood collection tube to handle a reduced internal volume for handling by equipment configured to handle standard-sized blood collection tubes having standard external dimensions.

Abstract: In an improved method for measuring the erythrocyte sedimentation rate (ESR) a pre-evacuated test tube (T) is used to collect a blood specimen. The tube (T) is made of a material such as glass or plastics and contains an anticoagulant agent. In order to facilitate mixing of the blood sample a surfactant such as an organosilicone fluid is provided in the tube (T) as an additive.

Abstract: A collection device for plasma preparation for diagnostic assays. The device comprises a spray-dried anticoagulant formulation on the interior surface of the device and a thixotropic polymeric gel. The device is an improvement over commercially available devices which contain liquid anticoagulant formulations, for use in nucleic acid testing that employ amplifications technologies including, but not limited to, polymerase chain reaction (PCR), branched DNA (bDNA) and nucleic acid sequenced based amplification (NASBA).
