Blood Type Test ABO-Rh
Blood Typing Test
|
INTENDED USE
Do you know your own blood type? Do you know your children's blood type? This information can be critical in a medical emergency when immediate blood transfusion/replacement is required. The blood typing kit uses the basic forward antibody method of blood hematology to provide the user with their blood type (A, AB, B or O) and rhesus factor (Rh negative or Rh positive) in a few minutes without the need for special laboratory supplies or training. By simply comparing the results of blood sample coagulation on the pretreated areas of the test card with a graphic picture chart, correct blood grouping is known. The blood typing kit is also excellent for classroom instruction and other educational applications.
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. A subcutaneous injection of
Rho D Immune Globulin can be given during pregnancy to prevent this immune
cross-reaction, which may be harmful to the developing fetus.
It is recommended that all pregnant woman and those who need a blood transfusion determine their blood type, especially the Rh factor. All donated blood has a blood type test performed on it so that donor and recipient blood types match. Paternity testing often involves blood typing, which may or may not be able to prove if someone could be the parent of a child using the basic dominant/recessive gene matrix calculation. There are other, rarer indications for blood typing, such as genetic studies.

DRAWING SAMPLE |
ADDING SAMPLE |
READ RESULTS |
|
Read all directions carefully. Using the pipette provided or other suitable device, add several drops of water to each of the pretreated test areas to activate the antibody sera |
Lay selected hand, palm up, against a flat table surface. Holding the lancet device in your hand firmly against the outside tip of your finger, press the trigger down until it clicks. The blood sample flow will begin |
Point your finger down directly over each cupped end of the special collection comb provided and fill each small cupped end (4) of the comb with a drop of blood. Details on the recommended amount are explained in the instructions |
after spreading the four samples in the special test areas using the comb device, the test will develop and coagulation patterns will form in each box. Compare the patterns to the color chart to find your blood type. |
INTERPRETATION OF RESULTS
 |
After the Blood typing test is completed and fully developed the test card will resemble the graphic to the right. Note that the appropriate identification boxes have been filled in with the name, address, date and contact information of the individual tested. Using the color chart provided on the left, coagulation is seen in cells two and four of the test card. Therefore correlating this result to the chart shows that the Blood type is A and the Rh factor is positive. The card can then be sealed with a clear plastic adhesive sheet to provide a permanent blood typing record for that individual. |
