A device for carrying out chemical or clinical testing of a liquid sample, for example a urine sample, by a specific binding assay, said device comprising a test component (2) which has a sensitised solid surface (2a) carrying an immobilised component of a specific binding pair relevant to the assay, and a handling piece (1), and characterised in that the test component (2) bearing the sensitised surface (2a) is removably mounted in spaced relationship with a removably mounted accessory component (4) carrying an accessory solid surface (5), and in that there is a space (4a) between the sensitised surface (2a) and the removable accessory component (4) to act as a container for sample liquid, so that when the device is contacted with a sample liquid source or immersed in liquid which is to provide the test sample, liquid of the sample can enter the space (4a) to contact the sensitised surface (2a), and the accessory surface (5) acts to retain and contain sample liquid in contact with the sensitised surface (2a) even after removal of the device from further contact with or immersion in the source of sample liquid, and in that the test component (2) is so formed that after removal of the removable accessory component (4) the sensitised surface (2a) is left exposed and accessible to further treatment liquid such as washing liquid and/or reagents. |
