There are 9 blood group system kinds that enable to give correct blood to patient at the time of transfusion. This means the blood of donor has to be compatible with patient’s blood to lessen reactions during transfusion and prevent further consequences. Talk to your gp and perform necessary tests on time. Go through this blogpost to know about blood type test and detect your type.

About 4 blood groups

The blood consists of antigens, a part of the immune system of your body with red blood cells, platelets and white blood cells. Antigens are sugars or proteins which cover the surface of red blood cells. Some of these antigens determine the blood group you actually belong to.
You will find four types of ABO blood groups which are A, B, O and AB. All these denote the presence of several antigens on red blood cells. Blood group A means you are having A antigen but blood group B means you have B antigen. Blood group AB has A as well as B antigens present on surface but blood group O do not have any antigen.
People having D antigen are RhD positive while the ones who do not have D antigen are RhD negative. So, the positive as well as the negative suffix on blood types comprising of A+ and B-denotes RhD type or Rhesus D type.

Importance of blood grouping in transfusions

Blood grouping is extremely important at the time of transfusion. When a patient is given blood with blood type that is incompatible with blood type the patient gets, it may lead to be clumps in patient’s blood. The body may form antibodies for attacking antigens on blood cells which can lead to rejection.
For example, a patient with blood group B will produce Anti-A antibodies naturally in the blood plasma. When blood group B patient gets blood group A red cells, the Anti-A antibodies in the plasma of patient leads to blood group A red cells which can be risky for life.
In the same way, a patient with blood group A has naturally occurring Anti-B antibodies in blood plasma. When the patient having blood group A gets blood group B red cells, the Anti-B antibodies in the plasma of patient will lead the blood group B red cells to clump which can be life threatening.
The packed blood group O red cells can be given safely to other blood groups. An individual may have either blood group A, B, AB or O which can be RhD positive or RhD negative. This means the person may be having any of these RhD and ABO blood groups. These are A+, A-, B+, B-, AB+, AB-, O+, O-.
The most common blood group is O+ and the rarest blood group is AB-. People who are RhD positive may be given either RhD positive or RhD negative blood while people who are RhD negative blood can receive RhD negative blood only. So, identifying the blood group of a patient is a quick process and the best platelets to provide for the transfusion method are indeed serious.
It is yet possible for the blood type to change in certain circumstances. Most red blood cells are made in the bone marrow and the transplanted bone marrow from donor or different kind causes your blood type to change in due course. Thus, monitoring the blood types is very important for other transfusions during this transition phase.

Safe blood groups in plasma and blood transfusion

Plasma is actually the biggest blood component and yellow liquid for holding red blood cells, platelets, white blood cells and other cellular components. As plasma has enzymes, antibodies, salts, water and other proteins, you will know about blood type through these contents and plasma also includes a blood type.

Importanceof blood grouping at the time of pregnancy

The blood type and blood type test are extremely important for women who are pregnant. This is because blood groups are hereditary and pass from either the mother or the father. When the father of the baby has RhD positive and baby’s mother has RhD negative, the baby can be RhD positive which can be the reason for compatibility issues. If the baby has RhD positive blood group, it might be the reason for medical complications. So, the mother gets special drug for preventing her body from producing antibodies against the blood cells of baby.

How blood grouping reagents generally work

Blood group reagents are effective solutions that help to know about blood groups. The reagents comprises of antibodies for detecting the presence of appropriate antigens on the surface of red blood cells.
The reagents may lead to clumping on testing red blood cells which carry necessary antigen. There is no clumping of the test and red blood cells denote absence of right antigen.
Different techniques are there to detect blood groups. All these methods depend on the binding of an antibody to necessary antigen known as agglutination. The agglutination is visible macroscopically with clumping together of red blood cells.
Thus, you may conduct private blood type test in London by consulting with your private gp and know your blood type.
