How do I know if my blood is positive or negative?
The Rh factor is simply a protein that is found on the covering of the red blood cells. If your red blood cells have this protein, you are Rh positive. If your blood cells don’t have this protein, you are Rh negative.
How do I know my blood group is positive?
When blood typing is done to see if you have Rh factor on the surface of your red blood cells, the results will be one of these:
- Rh+ (positive), if you have this cell surface protein.
- Rh- (negative), if you do not have this cell surface protein.
Is O blood positive or negative?
O negative is the universal blood type. O negative blood type can only receive O negative blood. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.
How can I find out my blood type at home?
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to prick a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
