EldonCard

Eldoncard INC Blood Type Test (Complete KIT) - Find Out if You are A, B, O, AB & RH- Results in Minutes - Air Sealed Envelope, Safety Lancet, Micropipette, Cleansing Swab - 1 Pack

Free Shipping

Main Highlights

What is the EldonCard: You can learn your blood type in just a couple of minutes using the Eldon Blood Typing Kit. The EldonCard is used for ABO and RHD blood grouping. The card is perfect for individuals to understand what their blood group is. The Blood Typing cards are accurate and can be used in the home and once completed the card can covered for future reference.
Why do I need the EldonCard: Your blood type is inherited from your parents and determined by the presence or absence of certain antigens and antibodies. The EldonCard is made of a special type of plastic upon which dried antibody formulations are placed. The EldonCard is a reliable, durable, and a flexible point-of-care blood typing system.
How EldonCard Works: The type of antigen you have tells us what your blood type is. While there are more than 20 blood-type systems, A, B, O and Rh (Rhesus) factor are by far the most important types. 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.
EldonCard Accuracy: 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 results are in-line with laboratory-based tests.
Where and Who can use it: EldonCard is used by hospitals, blood banks, blood centres, where it can be used for general blood typing and for bed side testing. Given the flexibility, durability and accuracy of the EldonCard, it can be used outside hospitals and clinic environments. Often it is used within practitioner clinics, humanitarian settings, remote locations, battlefields, classrooms, private homes, and in many emergency, situations calling for a speedy and reliable test.
