Abstract

PROBLEM TO BE SOLVED: To determine a blood type with high accuracy by supporting a substance specifically-bonded to a blood type substance, and using a porous body in which erythrocyte is movable in a capillary phenomenon. SOLUTION: A porous sheet or membrane-form material, foam, or woven material whose hole diameter is approx. 5-100 μm is used as a porous body, so that erythrocyte is movable in a capillary phenomenon when an erythrocyte- containing liquid sample is brought into contact with it. An antibody such as an anti-A antibody, an anti-B antibody, and an anti-D antibody, and lectin such as anti-A lectin and anti-H lectin are used for a blood type specific bonded substance. Solution containing the blood type specifically bonded substance is applied to the porous body and it is dried to be supported by physical adsorption, or the blood type specific combining substance may be supported chemically by using a functional group such as an amino group and a carboxyl group in the porous body. The amount of support per unit area is approx. 0.01 μg-1 mg. The liquid sample containing the erythrocyte is supplied to the porous body, thus it is possible to determine a blood type from the presence/absence of the bonding of a specific bonded substance to be generated to the erythrocyte.

In the above determination of ABO blood type, when coloring derived from erythrocytes is observed only at the site carrying the anti-A antibody, it is necessary that the erythrocytes in the sample contain only type A antigen. Therefore, the blood type was determined to be type A, and if coloring derived from erythrocytes was observed only in the anti-B antibody-carrying site, the erythrocytes in the sample contained only the B-type antigen. Is determined to be B-type. In addition, when coloring derived from erythrocytes is observed in both the anti-A antibody carrying site and the anti-B antibody carrying site, the erythrocytes in the sample are type A and B
Blood type is AB because both types of antigens are present
If it is determined that the type, the coloring derived from red blood cells is not observed in any of the anti-A antibody carrying site and the anti-B antibody carrying site,
Since the red blood cells in the sample do not have both type A and type B antigens, the blood type is determined to be type O.

When used, coloring derived from red blood cells was observed only in the B-type determination part, and no coloring was observed in the A-type determination part. When AB-type diluted blood was used as the liquid sample, coloring derived from red blood cells was observed in both the A-type determination section and the B-type determination section. When O-type diluted blood was used as the liquid sample, no coloration derived from red blood cells was observed in any of the A-type determination section and the B-type determination section. Further, when Rh-positive diluted blood is used for the liquid sample, coloring derived from red blood cells is observed in the Rh basic type determination section, and when Rh-negative diluted blood is used for the liquid sample, Rh basic type determination is performed. No coloring derived from red blood cells was observed in the part. From these facts, if the blood type is determined using the test device of the present invention, the ABO type determination (table test) can be easily performed in a single operation, and the determination of Rh negative / positive can be performed simultaneously.
