Short Answer
O-negative blood is often called the universal red blood cell donor because it can usually be transfused to patients of any blood group during emergencies.
Detailed Explanation
O-negative blood contains:
- No A antigen.
- No B antigen.
- No Rh antigen.
Because of this, hospitals often use O-negative blood when there is no time to determine a patient's blood group, especially in trauma and emergency situations.
Since O-negative donors are relatively rare, regular donations are extremely important.
Key Points
• Universal red blood cell donor.
• Frequently used in emergencies.
• Rare but critically important.
• Always in high demand.
❤️ If you are O-negative, your blood has the extraordinary ability to save lives when every minute matters.
