| Blood groupsIntended Use:
 This fast, easy to use blood typing kit will give your clients or patients valuable information using only a finger-stick. The Eldoncard is a patented test card device that comes specially treated and impregnated with dried antibody sera Anti-A, Anti-B and Anti-Rh used universally for determining Blood Type by the forward typing method. After only a minute of coagulation, the test card to the left can be compared to the Results Chart (see below) to determine the correct blood grouping.Background: Blood typing is determined by the type of antigens or markers that are on the surface of red blood cells (either "A" or "B") and if there are antibodies to a portion of the blood type known as the Rh factor (either "positive" or "negative"). Blood type is inherited from, and dependent upon, the blood type of an individual's parents. In the case of a transfusion, a person's blood type needs to be compatible with the donor's blood type or an allergic-type reaction can occur resulting from the immune system of the recipient attacking the incompatible donor blood cells as invading organisms. Also, it is also very important to know the Rh factor status when woman is pregnant. If a pregnant woman is Rh negative and her baby is Rh positive, the mother's immune system can sometimes attack the baby's blood cells because of the differing blood types. All pregnant women should routinely have a blood typing test done to see if they are at risk. This blood typing should generally be done as part of routine prenatal care. Interpretation of Results:
Included with each test kit is a color results chart shown below. This chart illustrates the different test results possible on the Eldoncard. After the blood typing test is completed and fully developed, the Eldoncard will resemble one of the graphics on the chart. The blood type and Rh factor can now be determined by matching the results on the card with the chart below. | |
