  • Blood filtering metering device
    Patent number: 4987085
    Abstract: Constructions are provided for removing interfering red blood cells from a blood sample and providing a measured amount of serum or plasma to a pad. The pad serves as a bridge for the transfer of reagent between two bibulous strips, resulting in transfer of reagent solution through the pad and transport of a material to be measured to the measuring region of the strips. Particularly, glass fiber membranes are used in conjunction with cellulosic membranes to minimize red blood cell lysis, remove red blood cells and provide a measured amount of sample.
