A method and a system for detecting in a sample (serum, plasma, whole blood, saliva or urine) of human or animal origin the presence or abscence of a single or multiple analyte is provided. The detection is simple and rapid. The detection system comprises a flow-through plastic device containing an absorbent pad with an affinity membrane. The device has specific areas of the membrane in which antigenic materials are immobilised. Each device has a control substance in one of the areas to act as a quality control material to check that the device is functioning correctly. In the case of antibody detection, the control material used is normally human IgG. In the case of antigen detection, the control material can be a specific antigen. In a multi-analyte detection system, any one of the discrete areas can be used for a specific control if desired. Also provided is method and apparatus for the detection in a sample of the presence or abscence of antigenic substances, antibodies or haptens using the above mentioned cassette device. It can be used for screening of the TORCH panel, for screening of a drugs of abuse panel, for auto-immune antibody screening, for gastroenterology profile screening (H. Pylori, Parital cells, LKMI, M2), HIV testing, Microbacterium screening, screening for infectious diseases in birds and animals and other panel tests.
