Abstract (en)

[origin: WO9813519A1] A diagnostic test device contains a filter and exhibits improved transfer of fluid movement between assay components. The filter is an integral part of a strip and can be used for strip-testing of whole blood and other particulate-containing solutions generally. Surfaces of parts within the device are combined in particular ways to improve sample and reagent fluid movement and an optional chemical additive increase test quality. Whole blood HIV tests are exemplified that are easy to carry out and that show improved chemical resistance to false positive results.
