<p>A chromatic test device (10, 30) having a unitary planar fibrous body (20, 36) incorporating a sample application zone (26, 38), a separation zone (42) and a reaction zone (28, 40) and methods of using the device are disclosed. The application zone (26, 38) of the device is in fluid communication with a first absorbent means (44) and the reaction zone (28, 40) is in fluid communication with a second absorbent means (48) in order to establish bilateral flow of the fluid component of a sample applied to the fibrous filter body.</p> |
