ABSTRACT:
The invention involves an apparatus useful in analysis of liquid samples. At least 3 zones are provided which contain reactants which interact with the analyte and each other, leading to the detection reaction. The apparatus also has a fluid application means for reception of a liquid, and a waste zone, which absorbs excess liquid after the detection reaction has taken place. The fluid application means and waste zone are positioned at opposite ends of the apparatus.
