Knowing their blood group can help you better understand your health and be more informed about potential treatments.
In this article, I will explain how a person can identify their blood group investigate what type blood group it is.
What is a blood group?
A blood group is the classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. The presence or absence of substances called antigens helps determine blood type. Antigens are involved in triggering the body’s immune response.
A person may have A antigens, B antigens, both, or neither on the surface of their red blood cells. They may also have a protein called the Rhesus (Rh) factor.
The first stage in identifying blood type involves a test called ABO typing. This will determine which of the following four main blood types a person has. Thus;
A: the presence of just the A antigen
B: the presence of just the B antigen
AB: the presence of both antigens
O: the presence of neither antigen
The second stage involves identifying the presence (+) or absence (-) of the Rh factor in the person’s blood.
Incorporating the four ABO types and the two Rh types, there are eight common blood types:
How to determine your blood group at home.
Most people usually visit a clinic or doctor’s office to find out their blood group. However, there are ways of determining your blood group at home.
A person can identify their blood group at home using a rapid blood typing kit.
Using the kit requires you to prick a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
When one or more of the blood type antibodies or the Rh factor is present in the blood sample, the test produces a “clumping” of the blood. Typically, if clumping does not occur, the person’s blood type is O-negative.
You can purchase a home testing kit from a pharmacy or online.
Are you afraid of blood? Well, I have good news for you also. You can also test your blood group without using blood or pricking your finger. You might be wondering how is that possible? Well, you can also use saliva to check your blood type.
Some people produce the characteristic antigens in their saliva. According to 2018 research from the National Institute of Health (NIH), if a person does secrete these antigens in their saliva, a sample of dried saliva can reliably indicate their blood type. However, it is important to note that not everyone secretes these antigens, and this method does not necessarily indicate the presence or absence of the Rh factor.
Once you’ve been able to identify your blood group. It is expected you take note of these.
If you have;
Type A blood, you cannot receive type B or AB red blood cells.
Type B blood cannot receive type A or AB red blood cells.
Type AB blood can receive type A,B, AB, or O red blood cells.
While it is not often necessary for a person to know their blood group, this information can be useful.
You can help your family, relatives and friends by share to them also.
