Introduction
If one parent has type O blood and the other has type AB blood, their child may have either type A or type B blood. The ABO blood group system is a commonly used clinical blood typing system, determined by the presence of specific antigens on the surface of red blood cells. Blood types are inherited from parents. Parents with type O blood lack both A and B antigens on their red blood cells; therefore, they cannot pass either the A or B antigen to their child.
In today’s society, each person has a unique blood type, and many parents are unaware of their child’s blood type. So, what blood type will a child have if one parent is type O and the other is type AB?
What blood type can result from a type O and type AB parental combination?
When one parent has type O blood and the other has type AB blood, the child may have either type A or type B blood. The ABO blood group system is one of the most commonly used clinical blood typing systems, determined by the presence or absence of specific antigens (A and B) on the surface of red blood cells. Blood type is inherited from parents. Type O individuals lack both A and B antigens on their red blood cells; therefore, they cannot pass either the A or B antigen to their offspring.
Type AB individuals possess both A and B antigens on their red blood cells and thus may pass either the A or B antigen to their children. Consequently, a child born to a type O and a type AB parent may inherit either the A or B antigen—resulting in either type A or type B blood.
Recommendations: To determine your newborn’s blood type, visit a reputable hospital for blood testing. Precautions: If planning pregnancy, both prospective parents should abstain from smoking and alcohol consumption, as these habits negatively affect fertility. Smoking and alcohol use must also be strictly avoided during pregnancy, and exposure to secondhand smoke should be minimized. Adopt healthy lifestyle habits—including adequate sleep—and maintain a balanced diet rich in high-quality, protein-rich foods to strengthen immunity. We hope this information is helpful to you!
