PCT No. PCT/GB92/02074 Sec. 371 Date Apr. 8, 1994 Sec. 102(e) Date Apr. 8, 1994 PCT Filed Nov. 10, 1992 PCT Pub. No. WO93/10456 PCT Pub. Date May 27, 1993.The present invention relates to a device for performing biochemical diagnostic assays. The device, which is preferably provided in a self-contained disposable form for use in extra-laboratory conditions, has two liquid flow channels of porous material which transfer liquid by capillary flow to a common site in sequentially timed manner following simultaneous application of the liquid to the ends of the channels. The channels are formed by superposed layers of porous material separated by an impervious layer except for one or more areas over which the layers are engaged for liquid flow therebetween. A number of channel pairs can be formed in the layers for simultaneously performing plural test procedures.
