Rh blood type is determined by the presence or absence of the D antigen. People who are Rh positive have the D antigen and those that are Rh negative lack this. Some people have a variant of the D antigen, called Du. Presence of Du antigen causes lab results to report the blood type as Rh negative, although the patient behaves as an Rh positive would. Du negative means a "true Rh negative" result.

Can two negative blood factor parents create a negative blood factor baby?

Yes, two parents with negative blood factors (e.g. O-) can have a child with a negative blood factor (e.g. O-). Blood type inheritance follows specific patterns, so it is possible for two negative blood factor parents to pass on the negative factor to their child.


Can you give A positive blood to A negative blood?

No. The Rh Negative blood group is formed by an absence of the Positive factor.


Can a negative blood type and a positive blood type parent a negative blood type child?

Yes, it is possible for a negative blood type parent and a positive blood type parent to have a negative blood type child. This can occur if the positive parent is heterozygous for the Rh factor gene, allowing for the possibility of passing on a negative Rh factor to the child.


What blood type is rh factor?

it defines if the blood type is positive(+) or negative(-).


What makes A negative blood?

A person with A negative blood may have genotype AO or AA. The genotype for the Rh factor must be negative in both alleles.

The Rhesus factor, also known as the Rh factor, is an antigen that exists on the surface of red blood cells. People who have the Rhesus factor are considered to have a positive blood type. Those who don't have the antigen are considered to have a negative blood type.


Main differences in o positive,and o negative?

The positive or negative in the blood types refer to the Rh factor, which is an antigen. Antigens trigger immune responses. Being positive or negative for the Rh factor will impact who you can receive a blood donation from, and who you can donate blood to.


How can doctors determine positive or negative blood types.?

Doctors determine positive or negative blood types by testing for the presence or absence of a specific protein called the Rh factor on the surface of red blood cells. A positive blood type indicates the presence of this protein, while a negative blood type indicates its absence. This information is important for blood transfusions and pregnancy monitoring.


Can your blood type change from positive to negative?

No, your blood type cannot change from positive to negative. Blood type is determined by the presence or absence of certain antigens on red blood cells, not by the positive or negative Rh factor.


What is the difference between negative and positive blood type A?

What are parents blood group with their first baby is of blood group o negative?

If the first baby has blood group O negative, it means that both parents must have passed on an O gene and a negative Rh factor gene to the baby. Therefore, the parents could have blood groups A, B, AB, or O with negative Rh factor.


Where does the positive and negative for blood come from?

The positive and negative blood types come from the presence or absence of certain antigens on the surface of red blood cells. Blood type A has A antigens, B has B antigens, AB has both A and B antigens, and O has neither A nor B antigens. The positive or negative designation refers to the presence or absence of the Rh factor antigen.
