Collection tubes apparatus, systems and methods |
| abstract |
Methods of producing collection tubes are presented. The methods include providing a separator substance that can rapidly polymerize in a short time to a desired hardness and disposing the separator substance within the lumen of the tube. The separator substance is formulated to have a density between an average density of a serum fraction of whole blood and a cell-containing fraction of whole blood, and to be flowable with whole blood. Upon centrifugation of a tube having blood, the separator substance forms a barrier between the whole blood fractions. The tube and barrier maintain stability of one or more analyte levels, including potassium and glucose, within 10% of their initial values before centrifugation for at least four days. |
