Abstract:
An apparatus for collecting a body fluid for testing for an analyte contained within said body fluid, said apparatus comprising:a conduit having a first end for admitting a body fluid and transporting said body fluid from said first end to a discharge end of said conduit; a reservoir for receiving and collecting a flow of body fluid from said discharge end of said conduit; a test space positioned to be in contact with said fluid in said reservoir after said fluid has accumulated within said reservoir to a transfer volume of fluid, said test space positioned for said fluid in said test space to be exposed to analyte testing components; said test space having a test space volume for residence of said fluid in said test space exposed to said components and with said transfer volume at least as great as said test space volume; said test space adapted to passively wick said fluid from said reservoir into said test space at a rate of flow greater than a rate of flow of said fluid into said reservoir from said discharge end of said conduit when said fluid in said reservoir attains said transfer volume; and said reservoir sized for fluid to flow into said reservoir from said conduit and be accumulated in said reservoir until attainment of said transfer volume.
