Abstract
A method and apparatus for controlling the absorption of a liquid sample through an absorbent layer (2) and reducing the effect of hematocrit by applying the sample on one side of the layer (2a) and providing an air gap (4c) on the opposite side, so that absorption is controlled by preventing the release of air from the air gap.
