Abstract (en)
[origin: WO9005906A1] A test device (12) and method for detecting an analyte in a liquid sample by treating the sample with liquid reagents to form a detectable product. The device (12) includes a reaction zone (32) capable of retaining the detectable product and a control absorbent (30) in liquid-transferring contact with the reaction zone (32). The control absorbent (30) has a predetermined liquid-absorbing capacity and is positioned such that when the control absorbent (30) is filled to capacity, it effectively meters a predetermined flow through the reaction zone (32). The device also includes (with or without the control absorbent (30)): an absorbent reservoir (38); means for retaining the absorbent reservoir (38) in a first position spaced apart from liquid-transferring contact with the control absorbent (30); and means for moving the absorbent reservoir (38) from the first position to a second position in liquid transferring contact with the control absorbent (30).
