Rhesus factor (Rh-factor)

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

The determination of the Rhesus factor (Rh) and Kell system antigens is an immunohematology test used to identify the antigenic profile of human red blood cells.

The Rh system includes several antigens, the most clinically significant being the D antigen. Its presence defines Rh-positive status, while its absence defines Rh-negative status.

The Kell system consists of additional red blood cell antigens with important clinical relevance, even though they are less frequently encountered.

Rh and Kell typing is essential for assessing blood compatibility and plays a key role in transfusion medicine and obstetrics, particularly in preventing maternal-fetal immune incompatibility.

Clinical significance

• prevent hemolytic transfusion reactions
• reduce the risk of immune complications during transfusion
• assess the risk of Rh incompatibility in pregnancy
• ensure optimal donor-recipient blood matching

Indications

• initial blood group determination
• preoperative assessment
• pregnancy planning and monitoring
• management of Rh-negative pregnant women
• transfusion compatibility testing
• blood donor evaluation

Procedure

Venous blood is collected from a vein in the procedure room. The procedure takes a few minutes and is performed by qualified medical staff.
