Short Answer
B-negative blood contains the B antigen but lacks the Rh (D) antigen.
Detailed Explanation
People with B-negative blood:
- Can donate red blood cells to B-negative, B-positive, AB-negative and AB-positive recipients.
- Can receive blood from B-negative and O-negative donors.
Because B-negative is uncommon, hospitals often depend on committed repeat donors.
Key Points
• B antigen present.
• Rh-negative.
• Less common.
• Essential for compatible transfusions.
❤️ Your rare blood type could be someone's only compatible lifeline.
