Blood group (ABO)

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Blood Group (AB0) is a laboratory test used to determine a person’s blood group according to the AB0 system, based on the presence or absence of A and B antigens on the surface of red blood cells.

The AB0 system includes four main blood groups:

• 0 (I) — neither A nor B antigens are present on the surface of red blood cells;
• A (II) — A antigen is present on the surface of red blood cells;
• B (III) — B antigen is present on the surface of red blood cells;
• AB (IV) — both A and B antigens are present on the surface of red blood cells.

Determining the blood group is important for selecting compatible blood and blood components in transfusion and represents relevant information in certain medical situations.

Indications

• determination of blood group;
• assessment before blood or blood component transfusion;
• preparation for surgical procedures, as recommended by a physician;
• blood group assessment during pregnancy, according to medical recommendations;
• preparation for blood donation;
• documentation of blood group in the medical record;
• other clinical situations, as recommended by a physician.

Procedure

The test is performed using a venous blood sample. The presence or absence of A and B antigens on the surface of red blood cells is determined in the laboratory, after which the blood group is established according to the AB0 system.

Only a qualified specialist can make an accurate diagnosis and determine the appropriate course of treatment.

This is because different laboratories may use different methods and units of measurement for similar tests.
