Abstract
A method for filtering a whole blood sample using a filter element constructed and arranged to block the passage of fibrous and particulate matter which may be present in a liquid sample, such as a whole blood sample, while allowing the blood cells to pass is disclosed. In one embodiment, the filter element is part of an in-line filter assembly which assembly may include two complementary mating components. One component may take the form of a coupling provided with a male threaded portion adapted to be received into and engage the female threaded portion of the complementary mating component. This complemnetary mating component may be another coupling or an analysis system component, such as a valve. Each complementary mating component is adapted to receive a liquid sample carrying conduit therethrough. The coupling is also adapted to receive a filter mount which holds a filter element constructed and arranged as discussed hereinabove. When the complementary mating components are assembled, their respective conduits and the filter element are brought into alignment and fluid tight seal. In an alterntive embodiment, the filter element is permanently retained in a section of conduit…
