Apparatus and methods for effecting chemical assays

摘要

590220 Disclosed is a test device (70) for testing for one or more characteristics of a sample carried by a sample carrier. The device (70) includes a holder (76) designed to hold the sample carrier substantially immovably in a predetermined relative position. A movement unit is operable to effect movement of a sample to be tested within the sample carrier and a sensing unit senses one or more parameters relating to the contents or characteristics of the sample. Diagnostic means determine a diagnostic condition on the basis of the sensed parameter or parameters and an information unit provides information relating to the diagnosis. The movement unit and the sensing unit include noncontact movement and sensing means respectively for moving a sample and for sensing said one or more parameters without contact with the sample. The device (70) is arranged so that in use there is no relative movement of the device (70) and sample carrier. The device (70) also includes a control unit.
