HLA DQ analysis (HLA DQ antigen test) is used to detect the presence of HLA DQ antigens on the surface of white blood cells. This test is an essential part of tissue compatibility assessment and plays an important role in various fields, such as organ transplantation and understanding certain immune disorders. The presence of HLA DQ antigens may indicate a genetic predisposition to certain diseases, including autoimmune conditions like celiac disease. The test is performed by drawing a blood sample, and results are typically available within a few days. The HLA DQ test helps doctors assess health risks and guide appropriate treatment strategies, contributing to improved patient care. This analysis is a valuable tool for understanding immune system responses and supporting medical decision-making.
