FDA Approves Grifols ID CORE XT Test For Molecular Red Blood Cell Typing

Test Offers Shortest Time to Reportable Results For US Hospitals, Reference Labs and Blood Centers - Efficient system analyzes 37 antigens of 10 blood group systems - Helps minimize allo-immunization risk in blood transfusions - Effective tool to generate "rare donor" database and expedite antibody identification in complex workups


The Food and Drug Administration (FDA) has approved the ID CORE XT molecular diagnostic test for in-vitro diagnostic (IVD) use in the United States. The blood group genotyping kit has been CE-IVD marked in Europe since 2014. The news was announced today by Grifols (MCE: GRF, MCE: GRF.P and NASDAQ: GRFS), a leading global producer of plasma-derived medicines and a leader in the development of innovative diagnostic solutions,

“We are proud to welcome ID CORE XT to our family of FDA approved blood typing products and services,” said Carsten Schroeder, President of Grifols Commercial Diagnostic Division. “This test reinforces our commitment to provide high-quality solutions that improve transfusion medicine practices and patient care.”

Molecular red blood cell typing provides significant advantages to patient and in donor management. Individuals requiring frequent transfusions are at a higher risk of receiving incompatible blood, which can result in life-threatening and costly adverse reactions1.

The ID CORE XT kit will benefit patients who require ongoing transfusions including individuals with hemoglobinopathies such as sickle-cell disease (SCD) and thalassemia. SCD affects approximately 100,000 Americans and is a major health concern in the U.S.2 Beta-thalassemia affects approximately one in 100,000 individuals worldwide.3

The kit will also be used for cancer patients who require more thorough blood typing. Other patients who may benefit from the kit include those with warm autoimmune hemolytic anemia, those who have recently received a transfusion and those undergoing daratumumab therapy.1,4

ID CORE XT types simultaneously 37 antigens of the following blood group systems: Rh, Kell, Kidd, Duffy, MNS, Diego, Dombrock, Colton, Cartwright and Lutheran, providing detailed information of the most clinically relevant blood groups. The predicted antigen profiles are used to build donor databases for the optimized management of antigen-negative units that are often needed to support the above mentioned patients.

The test will soon be available from Grifols as a kit to be used in the laboratory and as a send-out testing service from the Grifols Immunohematology Center in San Marcos, Texas.
