Abstract: A device for performing immunoassay tests includes a readable device for performing immunoassay tests having a platform with at least two sample receiving units. Each sample receiving unit is fluidly connectable to at least two test units, each of which includes a reagent incubation chamber fluidly connected to a separation unit connected to a detection chamber. The platform includes a volume indication unit for detecting the presence of a predetermined volume of the liquid biological sample, and a reading device for performing immunoassay tests. A recognition unit recognizes the presence of the readable device and/or extracts information from a legible identification unit of the readable device. A first optical sensor detects the presence of a binding pair of molecules in the separation unit and/or the presence of free molecules in the detection chamber. A second optical sensor detects the presence of a liquid biological sample in the overflow chamber.

Abstract: An assaying kit is for pre-transfusion blood group matching between two blood samples. The kit includes at least two assemblies (101,201) corresponding to the first and the second blood sample, each assembly has at least two test units (1). Each test unit (1) includes a reagent containing an antigen present on erythrocytes or an antibody able to bind to an antigen present on erythrocytes. Each test unit (1) also includes a membrane (2) permeable to free erythrocytes (6) and impermeable to hemagglutinated erythrocytes. The antibody contained in the first test unit for both the first assembly (101) and the second assembly (201) corresponds to a first blood group and the antibody contained in the second test units for both the first assembly (101) and the second assembly (201) corresponds to a second blood group.
