| 摘要 |
An assay device comprising: a tube (1) having a removable top closure (2) on which is mounted an elongate member (4) associated with swab means (5) adapted to take up material to be assayed at the distal end of the elongate member; wherein the tube includes one or more frangible membranes (7) defining one or more compartments (3) each containing a compartmentalised agent (8), and the elongate member is movable, within the tube, to break the one or more membranes and bring said distal end into contact with the or each agent. Such a device can be used to assay microorganisms, by taking the microorganisms up in liquid on the swab, introducing the elongate member into the tube (1), and moving the elongate member (4) with respect to the tube, to break the one or more membranes and bring taken-up liquid and its contents into contact with the or each agent. A conventional bioluminescence assay can then be used. |
