<p>The invention relates to a method of testing a liquid sample, a test unit, an and automatized system of a plurality of test units. The particular aim is a system for large scale testing patient blood samples, comprising a large number of test units at different locations and connected through a common control unit. In an individual test unit there is a liquid dosing chamber (5), hermetically closed packages of calibrator and control liquids (8, 9), closed liquid reagent packages (10), a liquid sample inlet (14) and an actuator (16) for dosing and mixing the reacting components as well as means for registering results from the reactions. The test unit can perform calibrating, control and test reactions automatically under surveillance of the control unit. The system can use the same packaged liquids in each of the test units, enabling calculation of averages of the control results and, through comparison of individual results with an average, letting faults be detected through results outside permitted deviations.</p> |
