Abstract
A method and device for separating blood into fluid and cellular fractions for diagnostic tests. The whole blood is introduced to a carrier containing a layer of carbohydrate which results in the rapid separation of the fluid from the cellular fractions. In a preferred embodiment, the device is fabricated in a sandwich design containing layers of carbohydrate and reagent material between two layers of plastic.
