The advantages Blood Group Testing

Introduction

Knowing your blood group helps to prevent a while lot of crisis in the future which includes not having a sickle celled child and other factors too.

In this session I’ll be talking about the advantages Blood Group Testing, and what’s gonna result to if ignored.

The blood is divided into groups based on the presence and lack of antibodies.

In addition, the presence and absence of hereditary antigenic compounds are taken into account while classifying.

Blood group types are inherited and reflect both the father and the mother’s contributions.

ABO Blood Group System

The ABO Blood Group System is a system for identifying blood groups.

Because any person over the age of 6 months has clinically significant anti-A and/or anti-B antibodies in their serum, ABO remains the most important in transfusion and transplantation.

Antigens and Antibodies

Antigens and antibodies are typically found in human blood.

There are two types of Antigens which happens to be Antigen A and antigen B.

There are also two types of antibodies which are Antibody A and Antibody B.

These Antigens will only be found in red blood cells, while antibodies will also only be found in white blood cells.

All humans can be grouped into one of three blood groups based on their antigen properties:

1. Blood Group A antigen A and antibody B

2. Antigen B and antibody A in blood group B

3. Antigen A and antigen B are present in blood group AB, but no antibody is present. 4. Blood Group O has no antigen but does have antigen A and antibody B.

When it comes to transfusions of human blood, the ABO system must be taken into account.

Karl Landsteiner was the first to discover the ABO blood group systems in 1901.

System of Blood Groups (Rh)

The presence or absence of the Rh antigen, also known as the Rh factor, on the cell membranes of red blood cells is used to identify blood groups (erythrocytes).

One is said to be Rhesus (Rh) factor positive if a certain protein is been found at the surface of your blood cells. If your Rhesus (Rh) factor test is negative it simply means the absence of this Protein.

Another important blood-group system is the Rh system (the meaning of Rh is Rhesus). When receiving blood transfusions, it is critical to match the Rh system.

Rh antigen was first discovered in Rhesus monkeys, hence the name Rh factor/system.

Rh negative (Rh-ve) refers to someone who does not have Rh antigen, while Rh positive (Rh+ve) refers to someone who has.

Rh positive happens to be the most common in the World. Having a Rh negative blood type is not a disease, and it usually has no negative consequences for your health. If you’re Rh negative and your kid is Rh positive, you’ll need to take extra precautions during your pregnancy (Rh incompatibility).

Note: Either parents can contribute to the Rh factor there child with end up having.(could be positive or Negative). Below we’ll talk about.

The Importance of Blood Group Testing

The significance of the RH Blood Group test.

• If both the mother and father’s Rh factors are positive, the child’s Rh factor will also be positive, thus no precautions are necessary.

• If both the mother and father’s Rh factors are negative, the child’s Rh factor will also be negative, thus no precautions are necessary.

• If the mother’s Rh factor is positive but the father’s is negative, the child’s Rh factor might be positive or negative, therefore no precautions are necessary.

• If the Rh factor of the mother is negative and the Rh factor of the father is positive, the child may be at risk.

• If the mother’s Rh factor is negative and the father’s Rh factor is positive, the infant could be Rh positive or Rh negative, necessitating the administration of Rh immune globulin ( The immune globulin prevents your body from producing Rh antibodies during your pregnancy.) Then if your child happens to be Rh positive, you’ll need to get injected again with “antiD” soon after the child’s birth to stop the mother’s blood cells from developing antibodies that will attack the red cells of a Rhesus positive kid in the future. Nothing happens if a baby is born Rh Negative.

If it’s her initial pregnancy there is no cause for alarm. This is because the child’s blood does not normally get to be mixed with that of the mother during pregnancy; Although, At the course of childbirth, the child and the mother’s blood will definitely mix, and the mother’s body will immediately begin to produce Rh antibodies because the Rh protein from the child is perceived as a foreign substance, which is where Anti- D comes into play.

Resultant of Rheus Rh factor Mismatch.

If the blood of a Rh negative mother comes into contact with the blood of a Rh positive foetal during pregnancy, it can result in:

• Difficulty in child birth

• Miscarriage

• Abortion

• Ectopic pregnancy: This occurs when a fertilized egg implants outside the uterus, generally in a fallopian tube.

• Trauma to the abdomen during pregnancy.

• A molar pregnancy: This is a noncancerous tumour that develops in the uterus that must be removed.

All what you have read it’s the importance of blood group testing.
