Device and method for collecting, preparation and stabilizing a sample

摘要

An assembly (20) device and method for collecting and testing fluid samples more specifically for preparing and stabilizing nucleic acid components in a closed system. The assembly (20) comprises a sample collection container (30) with preloaded testing reagents (44) and a safety separator (70) to contain the testing reagents during sample collection. A fluid sample is delivered to the container and the assembly is subjected to centrifugation whereby the centrifugal load causes the separator (70) to deform so that the separator migrates through the test reagents mixing the sample and reagents, and comes to rest atop the solids at the bottom of the tube.
