Blood Type and Rh Lab Test Information

Test 006049
Blood Type Test

This blood type test provide the user with their blood type (A, AB, B or O) and rhesus factor (Rh negative or Rh positive).

There are two distinct chemical molecules present on the surface of the red blood cells. These are:

One molecule "A" and the other molecule "B."

It is important that blood types be matched before blood transfusions take place. In an emergency, type O blood can be given because it most likely to be accepted by all blood types. However, there is still a risk involved.

Pregnancy and Blood Type and Rh:
It is particularly important for expectant mothers to know their blood's Rh factor. Occasionally, a baby will inherit an Rh positive blood type from its father while the mother has an Rh negative blood type. The baby's life could be in great danger if the mother's Rh negative blood attacks the baby's Rh positive blood. If this happens, an exchange transfusion may save the baby's life. The baby's blood can be exchanged for new blood that matches the mother's.
