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) systems and to ensure compatibility of patient/donor blood. Today EldonCards are based on the use of special formulations of selected monoclonal antibodies. The special qualities of the EldonCards are the following:
- Shelf-life 24 months at 5-37 °C
- Portable and compact
- Blood grouping on location
- Result after just 2 minutes
- Easy to learn, easy to use
- No need for refrigeration and daily controls
- Whole blood can be used down to 5 μl.
- No need for separation of red cells and blood plasma
An EldonCard is a standardised slide-test offering stronger agglutinations than home-made slide-tests. Using Kits with EldonCards, blood can be grouped outside the blood bank e.g. at the bedside just prior to a trans-fusion, in the practitioner’s clinic, on remote locations as ships and oil rigs, on the battle field, in the class room, in the private home, or in any emergency situation calling for a speedy and reliable test. EldonCards can be used as identification cards or as driving licenses. In countries with both rhesus positive and rhesus negative individuals the blood of all pregnant women must be grouped. The EldonCard will enable the practising gynaecologist to group his patient’s blood, and the patient does not need to visit a blood bank or a clinical laboratory.
