KNOW YOUR RHESUS COMPATIBILITY BEFORE SAYING YES!

     



  Rhesus factor is not a disease neither is it harmful to your health,knowing your blood type is very important for aspiring couples they should ensure they check their blood type and rhesus factor before commiting to go further,to avoid still birth and miscarriage etc..Also,it is very important when a blood transfusion is necessary.
       Rhesus factor(RH) is an antigen found in the red blood cells of most people.Those who have RH factor are said to be RH positive (RH+),while those who do not have are RH negative(RH-).
      A blood type is defined as the classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells(RBCs).A series of related blood types types constitutes a blood group system such as the RH or ABO system.The frequencies of the ABO and RH blood types vary from population to population.Blood types are very important when a blood transfusion is necessary.A patient must receive a blood type compatible with his or her own blood type.If the blood types are not compatible,red blood cells will clump together making clots that can block blood vessels and cause death.While blood types are 100% genetically inherited,the environment potentially can determine which blood types in a population will be passed on more frequently to the next generation.
      There are four major blood groups determined by the presence or absence of two antigens(A&B)on the surface of red blood cells and compatible blood combinations.

BLOOD GROUP ANTIGEN
A                          Has only "A" antigens on red cells and ("B" on anti body in the plasma).

B                          Has only "B" antigens on red cells and ("A" on anti body in the plasma).

AB                        Has both "A" and "B" antigens on red cells (but neither "A" nor "B"anti body in the plasma).

O                              Has neither "A" nor "B" antigens on red cells (but both "A"and "B" anti body are in the plasma).

           Here are list of compatible blood donors:
BLOOD TYPE    DONATE TO            RECEIVE FROM
A+                        A+, AB+                     A+, A- ,O+, O-

O+                        O+,A+,B+,AB+          O+,O-

B+                        B+,AB+                       B+,B-,O+,O-

AB+                       AB+                           Everyone

A-                         A+,A-,AB+,AB-          A-,O-

O-                         Everyone                       O-

B-                         B+,B-,AB+,AB-          B-,O-

AB-                      AB+,AB-                     AB-,A-,B-,O-


   
N:B;According to the American Red Cross the rarest is AB(-),present in 1% of the Caucasians,in African Americans, it is even rarer.B(-) and O(-) are also very rare each accounting for less than 5% of the world's population.Some people with rare blood types bank their own blood in advance of surgical procedures to ensure that blood is available to them.

FACTS ON BLOOD TYPES
-A total of 35 human blood groups systems are now recognized by the International Society of Blood Transfusion(ISBT).
-With regard to transfusions of packed red blood cells,individuals with type O Rh D negative blood are often called universal donors and those with type AB Rh D are called universal recipients.
-Many pregnant women carry a fetus with blood type which is different from their own,which is not a problem.
-A popular belief in japan is that a person's ABO blood type is predictive of their personality,character, and compatibility with others.


RISK FOR RHESUS INCOMPATIBILITY
   When a mother and her unborn baby carry different Rh protein factors their condition is called Rh incompatibility.It occurs when a mother is Rh-negative and her baby is Rh-positive the Rh factor is a specific protein found on the surface of red blood cells.
Like your blood type,you inherit Rh factor type from your parents.Most people are Rh-positive but a small percentage of people are Rh-negative.For example blood type AB+ might be written on your medical record.
Your Rh factor becomes important during pregnancy.If a woman is Rh-negative,then her baby is Rh-positive,it takes time for the body to develop antibodies,so firstborn children are not affected.However,if a mother became sensitized because of a miscarriage or abortion,her first birth may be affected by Rh incompatibility.
A mother can be exposed Rh-positive blood during certain prenatal tests.One example is amniocentesis.In this test,the doctor uses a needle to remove some of the fluid from the sac around the baby.This fluid can be tested for problems in the developing fetus.
Medications can help with this condition to ensure that the mother and baby are healthy.


TREATING RH INCOMPATIBILITY
   Treatment focuses on preventing the effects of the incompatibility.In mild cases, the baby can be treated after birth with:

-A series of blood transfusions.
-Hydrating fluids.
-Electrolytes which are elements that regulate metabolism.
-Photo-therapy.

She can prevent effects of Rh incompatibility by getting an injection of Rh immune globulins (Rhlg) Rhogam during her first trimester,during a miscarriage,or while having any bleeding during her pregnancy.This blood product contains antibodies to the Rh factor.If the baby has Rh-positive blood,she should get a second injection a few days after giving birth.
      In very rare and serious cases,a series of special blood transfusions can be performed while the baby is in the uterus or after delivery.However,the success of Rhlg shots has made this treatment only necessary in less than 1% of cases of Rh incompatibility in the United States,according to the Nemours Foundation.

EFFECT OF RHESUS INCOMPATIBILITY
-Brain damage to the baby.
-Fluid buildup or swelling in the baby.
-Seizures.
-Anemia.
-Heart failure.
-Death of the baby can also occur.                        

      In conclusion,rhesus incompatibility is becoming a problem or challenge because of lack of knowledge and ignorance of man.Therefore,rhesus compatibility should be given a due consideration before going into marriage to avoid birth complications and all what not.
