Abstract: A chain-of-custody form has integrated removable specimen seals, and the form may be used to identify a test sample collected from a donor and to document the handling of the test sample. The form may be printed upon a single sheet that has a first portion and a second portion. The first portion includes a first section having one or more spaces for recording demographic and testing information, and one or more indicia of the information to be recorded in one or more marked spaces; and a second section having a marked space for the donor to affix a signature and one or more indicia of the purpose of the space. An identifier that is unique to the form is recorded within the first portion and within the second portion. The identifier includes an specimen identification number or some other method of specimen identification such as a bar-code.

Abstract: A system for processing a fluid sample includes a tube and a piston. The tube has an open end and a closed end, and a volume defined therebetween. The volume is further defined by an interior surface of the tube. The tube is designed to receive a collection media holding the fluid sample. The piston has a first side and a second side, and is designed to be inserted into the tube via the open end of the tube. The piston is further designed to be translatable within the tube, and to compress the collection media between the closed end of the tube and the first side of the piston such that at least a portion of the fluid sample is removed from the collection media and driven to the second side of the piston.
