A method for detecting an analyte in a liquid composition, said method comprising: a) providing a test device having a proximal and a distal end, said test device configured to allow lateral flow from the proximal to the distal end, said test device comprising a solid support comprising the following regions in sequence from the proximal to the distal end: i. a sample receiving region, ii. a conjugate region comprising a labeled receptor capable to bind the analyte and a labeled control reagent, iii. a detection region comprising at least two zones: A. a detection zone comprising an immobilized binding agent capable of binding the labeled receptor, when said labeled receptor is unbound by analyte from the sample, and B. a control zone comprising an immobilized binding agent capable of binding the labeled control reagent, iv. an absorbing region, b) contacting the liquid composition with the sample receiving region of the test device, c) allowing said liquid composition to move from the sample receiving region through the conjugate region and the detection region to the absorbing region, so as to allow said liquid composition comprising the labeled receptor and the labeled control reagent to contact the detection zone and the control zone, d) detecting a signal at the detection zone and a signal at the control zone, wherein i. the absence of analyte in the sample is indicated by the presence of a signal at the detection zone that is more intense than the signal at the control zone, and ii. the presence of analyte in the sample is indicated by the absence of a signal at the detection zone or the presence of a signal at the detection zone that is less intense than the signal at the control zone, wherein the section of the device between the proximal and the detection region comprises a compound selected from the list consisting of methylcellulose, carboxymethylcellulose, hydroxymethylcellulose, carboxyethylcellulose, and hydroxyethylcellulose. a) providing a test device having a proximal and a distal end, said test device configured to allow lateral flow from the proximal to the distal end, said test device comprising
