Short Answer
Blood group A is one of the four main ABO blood groups. People with this blood group have A antigens on their red blood cells and anti-B antibodies in their plasma.
Detailed Explanation
The ABO blood group system classifies blood based on the presence or absence of A and B antigens on red blood cells.
People with blood group A:
- Have A antigens on red blood cells.
- Have anti-B antibodies in plasma.
- May be either A-positive (A+) or A-negative (A−) depending on their Rh factor.
Blood group A can donate and receive blood only from compatible blood groups to ensure safe transfusions.
Key Points
- One of the four ABO blood groups.
- Contains A antigen.
- Contains anti-B antibodies.
- Exists as A+ and A−.
