A device for performing immunoassay tests comprising: a. a readable device for performing immunoassay tests comprising a platform which comprises at least two sample receiving means for receiving at least one liquid biological sample from at least one donor and at least one donor differentiation means for differentiating different donor types; each sample receiving means is fluidly connectable to at least two test units, each of said test units comprises at least one reagent incubation chamber which is fluidly connected to at least one separation means, said separation means is fluidly connected to at least one detection chamber , characterized in that the platform comprises at least one volume indication means for detecting the presence of a predetermined volume of the liquid biological sample. b. a reading device for performing immunoassay tests comprising at least one housing in which an aforementioned readable device is insertable, said housing is connected to at least one rotational means for rotating the readable device at a predetermined rotation speed; a lid movable between an open position in which the readable device is visible and a closed position in which the readable device is not visible; at least one recognition means for recognizing the presence of the readable device and/or for extracting information from the legible identification means of the readable device; at least one first optical sensor which detects the presence of at least one binding pair of molecules in the separation means of the readable device and/or the presence of free molecules in the detection chamber of the readable device, and; at least one second optical sensor which detects the presence of a liquid biological sample in the overflow chamber of the readable device. a. a readable device for performing immunoassay tests comprising a platform which comprises at least two sample receiving means for receiving at least one liquid biological sample from at least one donor and at least one donor differentiation means for differentiating different donor types; each sample receiving means is fluidly connectable to at least two test units, each of said test units comprises at least one reagent incubation chamber which is fluidly connected to at least one separation means, said separation means is fluidly connected to at least one detection chamber , characterized in that the platform comprises at least one volume indication means for detecting the presence of a predetermined volume of the liquid biological sample. b. a reading device for performing immunoassay tests comprising at least one housing in which an aforementioned readable device is insertable, said housing is connected to at least one rotational means for rotating the readable device at a predetermined rotation speed; a lid movable between an open position in which the readable device is visible and a closed position in which the readable device is not visible; at least one recognition means for recognizing the presence of the readable device and/or for extracting information from the legible identification means of the readable device; at least one first optical sensor which detects the presence of at least one binding pair of molecules in the separation means of the readable device and/or the presence of free molecules in the detection chamber of the readable device, and; at least one second optical sensor which detects the presence of a liquid biological sample in the overflow chamber of the readable device. <EOS>
