what is Rh factor pls explain in detailrn

Scientists sometimes study Rhesus monkeys to learn more about the human anatomy because there are certain similarities between the two species. While studying Rhesus monkeys, a certain blood protein was discovered. This protein is also present in the blood of some people. Other people, however, do not have the protein. The presence of the protein, or lack of it, is referred to as the Rh (for Rhesus) factor.

If your blood does contain the protein, your blood is said to be Rh positive (Rh+). If your blood does not contain the protein, your blood is said to be Rh negative (Rh-).

Rh factors in pregnancy:

Most people are Rh positive. This factor does not affect your health. During pregnancya woman is at risk when she has a negative Rh factor and her partner has a positive Rh factor. This combination can produce a child who is Rh positive. While the mother's and baby's blood systems are separate there are times when the blood from the baby can enter into the mother's system. This can cause the mother to create antibodies against the Rh factor, thus treating an Rh positive baby like an intruder in her body. If this happens the mother is said to be sensitized.

A sensitized mother's body will make antibodies. These antibodies will then attack an Rh positive baby's blood, causing it to breaking down the red blood cells of the baby and anemia will develop. In severe cases this hemolytic disease can cause illness, brain damage and even death.


Rh factors in blood transfusion:

A person who is Rh-negative (whose blood cells do not have Rh antigen) may have an immune reaction if Rh-positive blood cells enter their bloodstream during blood transfusion.

The Rh (Rhesus) blood group system (including the Rh factor) is one of thirty current human blood group system. Clinically, it is the most important blood group system after ABO. At present, the Rh blood group system consists of 50 defined blood-group antigens . Besides its role in blood transfusion, the Rh blood group system—specifically, the D antigen—is used to determine the risk of hemolytic disease of the newborn (or erythroblastosis fetalis).

if a mother is having Rh-ve blood factorthen her blood group will be among A-ve,B-ve,AB-ve or O-ve.

if a mother is having Rh+ve blood factorthen her blood group will be among A+ve,B+ve,AB+ve or O+ve.


it will be dangerous for her baby if she is having Rh+ve man(father)

Rh is an antigen present on the surface of RBC's .If the Rh antigen is present on the surface those individuals are called as Rh+ ve and if the Rh antigen is not present those individuals are called as Rh-ve

hope it helped u
