    摘要: A sampling assembly for simultaneously testing a liquid biological sample for a plurality of hormones and method thereof are described. A sampling membrane includes a dry porous carrier having a proximal end narrower than a distal end and forming a unidirectional liquid flow channel. The distal end includes a plurality of tines arranged and separated by substantially regular spacing. Each tine defines a dye zone including a dye-tagged antigen-specific antibody at a distal end. The sampling membrane further defines a set of focusing recesses along each side of the unidirectional flow channel end and a set of dispersal recesses between and adjacent to each tine. A plurality of test strips each include a dry porous carrier communicatively attached to the distal end of one such tine. Each test strip forms a unidirectional liquid flow channel and includes a testing zone comprising an antigen-specific antibody located distally from the dye zone.
