Abstract

A rotary fluid manipulator utilizable as a diagnostic device includes a porous body having fluid passages defined therein by fluid blocking means in the porosities of the body such as openings or slots in the body or compaction of areas of the porous body to define fluid passages therebetween. Various substances or binding partners such as receptors, immunoassay or other assay test materials and test specimens can be deposited on the porous body to permit various types of test to be made by rotation of the manipulator to cause conjunctive centrifugal and wicking induced flow of fluids deposited thereupon.
