Abstract
A lysis chamber of an assay device capable of producing lysis of cells in a sample fluid such as whole blood, said chamber comprising a surface which contacts the sample fluid when the sample fluid is placed into the assay device; and a lytic material immobilized on the surface, whereby cells of the sample fluid are lysed when they contact the lytic material. The chamber can delimit a capillary space, and lytic material can be saponin or a detergent. Methods employing devices comprising such chambers can assay for whole blood amounts of cyclosporin or hemoglobin A1c.
