Abstract
An improved capillary fill test device is described. The device is formed to have a capillary aperture designed and sized to facilitate the filling of the device with fluid incident to its use. The described improvements are particularly useful in the construction of capillary fill devices having a capillary flow conduit of reduced flow through cross-sectional area extending between a fluid sample receiving portion and a capillary fill test volume.
