In blood banking, what is the importance of utilizing O-negative blood?

• A. It can only be used for specific patients
• B. It is the universal donor type for red blood cells
• C. It is the most common blood type
• D. It has a higher oxygen-carrying capacity

Answer: (B)

O-negative blood holds a crucial role in blood banking because it is considered the universal donor type for red blood cells. This designation means that O-negative red blood cells can be transfused to individuals of any blood type without the risk of an adverse immune reaction. This is primarily due to the absence of A and B antigens on the surface of O-negative red blood cells, which are normally present in other blood types and can elicit an immune response if introduced into a person with different blood type antigens. This characteristic of O-negative blood makes it especially valuable in emergency situations where there might not be enough time to test a patient's blood type before a transfusion. During such critical moments, O-negative blood can be administered safely, providing essential support to patients in need of red blood cell transfusions. The other choices do not capture the essential function of O-negative blood as effectively. For instance, it is not limited to specific patients, nor is it the most common blood type—A and O types are generally more prevalent. Lastly, while O-negative blood does have a standard oxygen-carrying capacity like other red blood cells, this is not a defining feature for its universal donor status. Hence, the universal donor characteristic is what emphasizes the significance of O
