The former is called the main test, and the latter is called the secondary test. Its purpose is to verify whether the ABO blood type identification of the donor and recipient is correct, and to prevent hemolytic transfusion reactions. The announcement number is: CN216879484U. A test tube rack specially used for manual cross-matching inspection, including a base, a test tube body with one end penetrating and extending to the inside of the base is movably installed on the top of the base, and a control room is fixedly connected to the left side of the base, and an automatic cover opening mechanism is arranged inside the control room, a fastening assembly is arranged inside the base, and a control assembly is arranged inside the base, and the automatic cover opening assembly includes a cylinder fixedly connected to the inner bottom wall of the control room, and the output shaft of the cylinder is fixedly connected to a lifting plate.
