FIBRINOGEN ASSAYS USING DRY CHEMICAL REAGENTS CONTAINING MAGNETIC PARTICLES

摘要

An apparatus and a method for performing a fibrinogen assay are disclosed. The reaction slide bears a sample well (22) for receiving a liquid sam- ple and a reaction chamber (24) in fluid communi- canon with the sample well. The reaction chamber contains a dry reagent matrix in which is embedded a plurality of magnetic particles. A whole blood or blood derived sample added to the sample well is introduced simultaneously into the reaction dram- ber where it solubilizes the reagent, freeing the magnetic particles and allowing them to move in an oscillating pattern. This oscillating pattern is opti- cally monitored to measure the concentration of clottable fibrinogen in the sample.
