Most Effective Way to Find Out Your Blood Type

Blood Types

There is no denying the fact that your body constitutes blood, flesh, and bones. Of all these three, blood is one of the most vital constituents. In most cases, when you go for a medical checkup, the doctor might ask you about your blood group or blood type. If you have no idea about your blood type, you have come to the right place.

Generally, your body determines the blood type with the help of antigens. It is due to the presence of these antigens that the immune response of your body is triggered. There is much more to blood types than you know. So, we have come up with this blog. In this blog, we will share with you everything that you need to know about your blood type. We will precisely focus on blood typing, blood testing, and at-home blood typing. So, without further delay, let’s get into the details of the blog.

How can you determine your blood type?

To designate your blood type, you have to understand the antigens. There are four types of blood groups namely:

  • Type A with A antigen
  • Type B with B antigen
  • Type O with both A and B antigens
  • Type AB with both A and B antigens

After you determine the type of blood, you can move on to defining the blood in terms of the Rh factor. Here, Rh stands for the Rhesus factor. A person having Rh-positive means the surface of his red blood cells is filled with Rh antigens. On the other hand, if a person has Rh-negative, it means that the surface of his red blood cells is devoid of Rh antigens. With the help of this Rh factor, you can determine the eight different types of blood – A+, A-, B+, B-, O+, O- AB+, and AB-.

How to do blood testing type?

A person who draws blood samples from your veins for testing is known as a phlebotomist. For blood typing, the phlebotomist follows two steps – forward typing and reverse typing.

First, the doctor carries forward typing. In this step, the doctor mixes your red blood cells with the antibodies that are against the type A and type B blood groups. Next, the doctor checks if the blood cells stick against each other. Your blood cells respond to the antibodies when the blood cells stick to one another.

The second step is reverse typing in which the doctor mixes the liquid portion of your blood with the type A and type B blood groups. Those who have blood group A have anti-B antibodies in the serum and people with blood group B have anti-A antibodies. If you have blood group O, it means your blood contains both A and B antibodies.

If you want to undergo ABO testing, know that it includes both reverse and forward typing. The result you get from the forward testing is known as the blood group of a patient. Doctors conduct reverse typing after forward typing only to cross-examine the result of forward typing. Once the doctor gets a confirmed result, he will move on to mixing your blood with anti-Rh serum. When your blood cells get accumulated and form a clump, it means you have Rh-positive blood.

How to find blood type at home?

If you are not aware of your blood type, you can purchase some at-home kits to find out the blood type. To use these kits, first, you have to prick your finger and take some blood out. This will provide you with the blood sample for testing. Use a lancet to prick your finger. When you get two-three drops of blood, put it on the special card available in the kit.

After putting the blood drops on the special kit, be highly observant. Check out if your blood clumps or gets scattered. Every blood testing kit is different. While in some you will find a card, in some others you will find vials of liquids. However, all of them perform the same task.

Another beneficial way of finding your blood group without even spending a penny is by participating in a blood donation camp. While you go to donate blood, the doctor will test your blood group and then collect the sample. Many blood donation centers have separate arrangements for identifying blood groups. The report of the blood group will take at least two weeks to arrive.

Blood type inheritance

Generally, a person inherits his blood group from his parents biologically. However, this does not mean that your blood group will be always the same as that of your parents. If one parent has a blood type A, he or she can pass on antigen A or no antigen at all.

On the other hand, when the other parent has blood type B, he or she can give you either antigen B or no antigen at all. now, the child can have either A, B, AB, or O blood group. If both the mother and the father have an O blood group, the child also gets an O blood group.

Relation between blood transfusion and types

If you experience surgery or trauma and have lost a lot of blood, you suffer from a blood transfusion. For receiving a blood transfusion, it is highly essential to match the blood group of both the donor and the recipient. This is because the blood inside your body creates antibodies that are against the ABO antigens. These antigens are not present in your body naturally. Neither do they develop on their own.

If the blood of the donor does not match that of the recipient, the body will reject it right away. This is because the antigens in both blood types are different. According to medical terms, this rejection is known as an acute immune hemolytic reaction. This can be a dangerous and fatal reaction. When this reaction occurs in the body of a recipient, the antibodies in his body do not match with the blood cells. This impacts the kidney s.


Therefore, if you are unaware of your blood group, you can schedule an appointment for a private blood test in London to find out your blood type. Make sure to provide your blood sample in a reputed clinic to get accurate results.
