The invention discloses a micropipe for blood grouping, a one-piece ABO/RhD blood typing test card for blood grouping and a preparation thereof. The micropipe for blood grouping includes a gel, an antibody working solution and a serum separation gel from bottom to top in order. The antibody working solution comprises a blood group antibody and an antibody diluent which can make the blood group antibody maintain activity, and the serum separation gel having a specific gravity of 1.075-1.077 can perform thixotropy to turn the solid into the fluid in the presence of centrifugal force of 150 G to 300 G. The specific gravity of the antibody diluents is more than that of the serum separation gel and less than that of the erythrocyte. The one-piece ABO/RhD blood typing test card prepared by the micropipe can add peripheral blood directly to test, and has no need to test the blood sample after diluting the peripheral blood removed the erythrocyte by centrifuging. So that the sensitivity and specificity of the blood type test card are guaranteed, the operation steps of the traditional ABO/RhD blood typing test card are reduced, and the efficiency is improved. |
