Know Your Blood Type For Self-Testing of ABO and RhD Blood Groups Easy, Fast, Reliable 5 - 37 °C, 41 - 99°F Eldon Biological A/S Contains: Eldoncard 2511 (1) Skin Cleaning Swab (1) EldonSticks (4) Automatic Lancet (1) Eldon Foil (1) Plastic Dropper (1) Instruction for Use (1) Intended use The ELDON HOME KIT 2511 is a self-test kit to determine your blood type inside the AB0- and RhD blood group systems on an ELDONCARD 2511 with one test per card. The blood grouping systems The ABO System classifies blood into four possible blood types, A, B, AB and 0. The RhD group of the complex rhesus system classifies blood as either positive (RhD pos) or negative (RhD neg). If blood of one type is mixed with blood of another type, it will form clumps or clusters - the so-called agglutinates - except blood of type 0 RhD neg, which does not agglutinate with any other blood type. By mixing your blood with specific monoclonal antibodies on the ELDONCARD you can determine your blood type. Your genes determine your blood type. A blood type determination with the ELDONCARD is possible from the age of approximately 12 months and you will retain the same blood type for the rest of your life. How does the EldonCard function? The dried antibody reagents can be seen in circles on the ELDONCARD as spots colored green for Anti-A, red for Anti-B, yellow for Anti-D. A control circle with a blue spot serves to verify that the result is valid. Perform the test by dissolving the dried reagent in each circle with a droplet of water and mixing it with blood. It is essential to get sufficient volume of blood and to avoid transfer of liquid between the four circles. For this purpose, you use four ELDON STICKs to transfer blood to each circle and to stir the liquid thoroughly. The tilting steps described below are also essential to complete the test.
