The ABORhCard is a single-use, disposable blood typing device that makes it possible to quickly determine a person’s blood type and Rh status from a fingerstick of blood. Marketed as the ABORhCard—based on blood types A, B, AB, O, and Rh factor—the card serves as a “portable” test, eliminating the need for the instruments or other equipment, liquid typing reagents, and refrigeration traditionally used to determine a person’s blood group.The ABORhCard acts as a qualitative in vitro agglutination test that determines both the ABO blood group and Rh factor of an individual in approximately two minutes.
While the test cannot be used for blood bank processing of blood products, for determining RHD status for the purpose of administration of Rh immunoglobulin, or for blood screening prior to transfusion, it offers significant benefits, such as informing individuals about their blood type prior to donating blood.
Developed in part under funding from the U.S. Army Medical Research and Materiel Command and the Telemedicine and Advanced Technology Research Center in Fort Detrick, Maryland, the ABORhCard meets the U.S. Army’s requirement for a field-deployable test of potential blood donors in austere settings where there are limited laboratory capabilities, and serves as a device to help manage large volumes of donors in contingency operations such as national emergencies, mobilization, or military combat operations.
While other manual methods for blood typing are available, such products and methods generally either require liquid reagents that need refrigeration or they are used in an open environment, potentially subjecting the test to contamination. In comparison, the ABORhCard is a closed system that provides a user friendly, integrated test that produces a visible result in minutes following collection of a fingerstick sample of blood.
