If Ms. Brown were serving as a donor, what ABO blood types could receive her blood safely?
Ms. Brown has A+ blood type
To determine which ABO blood types could safely receive blood from Ms. Brown, we need to consider the compatibility rules for blood transfusions.
In general, ABO blood types can be categorized into four main groups: A, B, AB, and O. Each blood type has specific antigens (proteins) on the surface of red blood cells and corresponding antibodies in the plasma.
Ms. Brown has A+ blood type, which means she has A antigens on her red blood cells and Rh antigen (known as Rh factor) on the surface as well. Therefore, the ABO blood types that could safely receive her blood are:
1. A positive (A+): Individuals with the same blood type as Ms. Brown can receive her blood because they have compatible A antigens.
2. A negative (A-): Individuals with A negative blood type can also receive Ms. Brown's blood as the absence of the Rh factor in their blood plasma won't cause any adverse reactions.
It's important to note that the Rh factor only influences compatibility when it comes to positive or negative types (e.g., A+, A-, B+, B-, etc.), while ABO groups (A, B, AB, O) determine the compatibility within the positive or negative types.
It's worth mentioning that blood compatibility is not solely based on ABO blood types and Rh factor. Other factors, such as minor blood group antigens and compatibility testing, are also considered before blood transfusions are conducted.
