How common is weak D blood type?
Approximately 0.2% to 1% of routine RhD blood typings result in a “serological weak D phenotype.” For more than 50 years, serological weak D phenotypes have been managed by policies to protect RhD-negative women of child-bearing potential from exposure to weak D antigens.
Is Weak D positive or negative?
An individual with weak D has a decreased amount of D antigens expressed on the red cell. With current serologic testing, most individuals with weak D are typed as Rh-positive via direct agglutination testing using anti-D.
What is the golden blood type?
An Rh null person has to rely on the cooperation of a small network of regular Rh null donors around the world if they need the blood. Throughout the world, there are only nine active donors for this blood group. This makes it the world’s most precious blood type, hence the name golden blood.

How do I know my blood type?
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.
How can I test my blood type at home?
In at-home blood typing tests, they typically ask that you prick your finger with a lancet and put drops of your blood on a special card. After putting the blood on the card, you can observe the areas where blood clumps or spreads out, and then match those reactions to an included guide.
How did my blood type change?

This has been due to unusual circumstances, such as having a bone marrow transplant or getting certain types of cancers or infections. Not all of the changes in blood type are permanent.
What is weak D blood type?
Definition: The weak D phenotype (Du) is a weakened form of the D antigen that in routine D typing will react with some anti-D but not with others (when an immediate spin or 37° incubation is done). Weak D red cells have the D antigen, but have fewer D antigens per cell than normal Rh positive cells.
How do I identify my blood type?
The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.
Is having O positive blood good?
Over 80% of the population has a positive blood type and can receive O positive blood. That’s another reason it’s in such high demand. O positive 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.
