ELDON BIOLOGICALS A/S is a Danish manufacturer of dry format cards for blood grouping. Based on an invention by the Danish physician Knud Eldon, EldonCards have been manufactured and used for more than 40 years.
Over time millions of cards have been utilised to establish individuals’ blood group within the AB0-Rhesus (D) system and to ensure compatibility of patient/donor blood. Today, EldonCards are based on the use of special formulations of selected monoclonal antibodies.
The EldonCard is a product of the highest quality. It is ISO certified, CE marked in the EU, cleared by the US FDA, and registered with the relevant authorities in a range of other countries. The EldonCard is made of a special type of plastic upon which dried antibody formulations are placed. The EldonCard is a reliable, durable, and flexible point-of-care blood typing system.
The EldonCard is extremely safe to use. It is very accurate and using the card eliminates many of the possible human errors associated with the traditional laboratory-based methodologies, where blood type testing is done with liquid reagents on a glass plate. It also leaves a permanent record – the EldonCard – which can either be included in a patient journal or it can be given to the patient for safekeeping.
The blood is drawn by using a single-use safety lancet, which prevents accidental piercing by anyone picking up the lancet after it has been used for blood typing.
The EldonCard is extremely accurate. It has been tested against the standard blood typing procedure using directly agglutinating antibodies. Tests have been performed at several laboratories in different countries and the result is that there is a 99.9 percent concordance between the results achieved by the EldonCard and a test using a well-executed standard blood typing procedure.
