    摘要: A composition and process for permitting the separation of plasma or serum from whole blood. The composition includes glass fibers having an average diameter of from 0.2.mu. to 5.mu. and a density of 0.1 g/cm.sup.2 to 0.5 g/cm.sup.2. The process includes the steps of slowly trickling whole blood onto one side of a layer composed of the composition of glass fibers, whereby plasma or serum separated from the blood becomes available at another side of the layer. The total volume of the plasma or serum separated from the blood is limited to at most 50% of the absorption volume of the glass fiber layer.

    摘要: On a carrier layer there are arranged several test layers which are at least partly in fluid contact with one another, enabling liquid exchange. On the carrier layer are arranged an application zone, a detection zone for the production of a detectable signal characteristic of the analytical determination, which contains at least one said test layer which is a reaction layer, and an absorption zone with a test layer which is an absorptive layer of an absorbent material, wherein the reaction layer and absorption zone are positioned next to each other. Between the application and the absorption zone is a capillary-active transport path on the carrier layer which connects the application zone and the absorption zone. The reaction layer is arranged parallel to the transport path between the application zone and the absorption zone in such a manner that it is in liquid contact with a liquid transported in the transport path. The absorption zone therefore absorbs excess liquid and permits dosing the reaction layer with a reproducible amount of sample.
