ABSTRACT:
A test strip with a sample absorption capacity which can be preselected comprises a support member capable of supporting along at least two edges a reagent strip in which the support member also has absorbent material positioned to remove excess sample applied to the reagent strip. In a preferred embodiment an intermediate layer is also supported by the support member and positioned above the reagent strip. The intermediate layer removes components of the sample which would otherwise interfere with the analysis being made in the reagent strip. In a further embodiment of the invention a cover is applied to the support member, wherein the cover contains an opening for introduction of sample material.
