Am 16weeks pregnant and I tested coombs Indirect positive. Can it affect the baby or makes the baby abnormal?

It refers to blood . You have red blood in you as does your husband. On the outside of the cells there are sugar molecules- either A or B or neither. Each of you will contribute the genes so the infant will get one from you and one from him and have either type A or type B or type AB or type O (neither). There is another Rh system. The Coombs refers to antibodies that you have against blood cells. Disc with your OB.
