How to read the results

How to read the results The presence or absence of agglutinates Agglutinates may look different from field to field, see the examples below. The possible combinations of agglutinates and the corresponding blood types are shown to the right. Any test producing a weak agglutinate must be repeated. will show the blood type. If an agglutinate is seen in the control field, the result is invalid.

The Eldon Blood Type Test contains the EldonCard on which there are four circles with antibody reagents. These antibodies will agglutinate with the corresponding antigens, if you have the antigens in your blood. When you have dropped your blood on the four circles, some of them will start agglutinating and in the guide which comes with the Eldon Blood Type Test you can see which blood type you have according to which antibody fields react.

Knowing your blood type is important for several reasons. First of all you prevent the risk of receiving an incompatible blood type during a surgery or a blood transfusion (today your blood type will be tested and cross-matched against the donor’s blood type which brings the risk of receiving an incompatible blood type to a minimum).

Secondly, knowing your blood type is important if you are pregnant. If your blood is Rh-negative and your baby’s blood is Rh-positive there is a risk that your body will start producing antibodies against your baby’s blood, which can have deathly consequences for the baby.

Therefore, if your blood is Rh-negative and your baby’s blood is Rh-positive, you need to receive a shot called immunoglobulin. Immunoglobulin prevents antibody production and sensitization which means that you won’t produce antibodies against your baby’s blood.

The antibodies are typically not dangerous during your first pregnancy as chances are that you will not be exposed to your baby’s blood until you deliver it. However the antibodies you produce during your first pregnancy will wait until your next pregnancy, and if your second child is Rh-positive too, the antibodies will attack.

Some people would also like to know their blood type in relation to their diet and general health. There is a general belief amongst many people that eating according to your blood type will have a positive effect on your physical and mental health and your general wellbeing.
