Abstract:
An apparatus for isolating an analyte from a blood sample, the apparatus comprising:a separation member for receiving a portion of the blood sample, the separation member comprising a filter that selectively retains cellular components contained within the portion of the blood sample and delivers non-cellular components of the portion of the blood sample containing the analyte;a wicking bridge fluidly connected to the separation member such that the wicking bridge can receive the non-cellular components of the portion of the blood sample containing the analyte from the separation member, the wicking bridge comprising a strip of porous material for transporting the non-cellular components of the portion of the blood sample containing the analyte away from the separation member; anda quantitative collection member fluidly connected to the wicking bridge such that the quantitative collection member can receive the non-cellular components of the portion of the blood sample containing the analyte from the wicking bridge, the quantitative collection member being substantially free of any reactants for analyzing the analyte and comprising a swatch of material that is adapted for absorbing and retaining a specific quantity of the non-cellular components of the portion of the blood sample containing the analyte.
