  • Device for analysis for constituents in biological fluids
    Patent number: 5435970
    Abstract: The invention is a device for separating blood cells from biological fluids, preferably plasma from whole blood. The invention includes a nonabsorbent, porous unitary support, which is desirably made of glass fiber, and a blood cell binding composition, such as a lectin. This device provides a test kit for measuring a plasma analyte in whole blood. This kit separates plasma from the whole blood, exposes the plasma to reactants that detect an analyte, and provides a chromatic or other result in response to exposure to the analyte. A desirable embodiment of the device has a cover plate over the reaction pad to apply uniaxialy pressure to the reaction pad which controls migration of plasma. The invention includes a method for separating plasma from whole blood and a method for detecting an analyte.
