Definition

Noun 1. A blood group: One of the major human blood group systems. A person with this blood type has red blood cells that carry the A antigen on their surface and anti-B antibodies in their plasma.

Usage

• Group A is one of the four main ABO blood types (A, B, AB, O).

• "In the ABO system, if you have Group A blood, you can receive blood from donors with Group A or Group O."

Advanced Usage
