How to Donate Blood: Understanding Blood Types


A steady supply of blood is required in our community since it can only be preserved for a short period before being used. A sufficient number of healthy people must donate blood regularly to ensure that blood is always available whenever and wherever needed.

If one plans to donate blood soon, it pays to know and understand blood types.

Importance of Blood Types

In 1901, an Austrian scientist named Karl Landsteiner identified blood kinds. Because doctors used to believe that all blood was the same, many individuals died due to blood transfusions.

According to physicians, blood from two people with different blood types might clump together, which is harmful. This is due to the fact that the person receiving the transfusion has antibodies that will attack the donor blood cells, causing a dangerous reaction.

A blood transfusion must be safe and effective for both the donor and the recipient to have compatible blood types. Blood group A can safely receive group A blood, and blood group B can safely receive group B blood.

When a donor and recipient are an exact match and their blood through a process known as crossmatching, it’s optimal.

How Blood Types or Blood Groups are determined

The ABO System

Blood groups are determined by whether or not specific antigens (designated A and B) are present on one’s red cells.

These are the four main blood groups based on the presence or lack of A or B antigens:

  1. Only A antigens are found on red blood cells in A-type blood.
  2. Only B antigens are found on red blood cells in B-type blood.
  3. On red blood cells, AB has both A and B antigens.
  4. On red blood cells, O has no antigens A or B.

    The presence of A and/or B type antigens on the surface of the red blood cells determine the ABO blood type.

The Rh System

The positive or negative component of one’s blood type, like the ABO system, refers to chemicals that are present or absent on the surface of the red blood cells.

Around 50 distinct red blood cell antigens make up the whole Rh blood group system, but the most crucial is a protein called RhD. Rh-positive means the red blood cells have the RhD protein. A person is Rh negative if they don’t have it.


Different blood types

It’s all about the antigens—the numerous carbohydrates and proteins on the surface of our cells, including our blood cells—when it comes to determining one’s blood type (or blood group).

Blood type is determined by the antigens present in a person’s red blood cells. Antigens are determined by genes, which are a combination of one’s parents’ genes.

Although there are numerous blood type systems, most people are familiar with the ABO and Rh (or Rhesus) systems. These approaches result in the eight most common blood types – A+, B+, AB +, A-, B-, AB-, O+, and O-.

A + blood type

This blood type is one of the most frequent. This person can only give blood to others who are A+ or AB +

A- blood type

People with this rare blood type can give blood to anyone with the A or AB blood types.

B+ blood type

People with this rare type can only give blood to B+ or AB+ people.

B- blood type

This extremely rare blood type can give blood to anyone with the B or AB blood types.

AB+ blood type

People with this uncommon blood type can receive any type of blood or plasma. “Universal recipients” are what they’re called.

AB- blood type

Because anyone can receive this type of plasma, someone with this blood type is known as a “universal plasma donor.”

O+ blood type

One of the most frequent blood types is O+. This person can donate blood to anyone who has a positive blood type.

O- blood type

People with this uncommon blood type can donate blood to people of any blood type.


Blood Type Analysis

A blood test can be used to determine a person’s blood type.

A healthcare provider will take a small sample of blood, generally from the person’s arm, to test it.

A technician in a lab mixes the person’s blood with three different drugs to see how they respond. A antibodies, B antibodies, or Rh factor will be present in each sample.

In each situation, the antibodies will elicit a distinct reaction. It will clump if the blood is incompatible. The technician can determine a person’s blood type by observing these reactions.

A technician will test the reaction by mixing a sample of the donor’s blood with that of the recipient before allowing the person to receive donated blood.

Before any blood or blood products are used, specialist technicians thoroughly test them.

Donate blood: Best Blood Type to Donate

Type O- red blood cells are the safest to give to someone in a life-threatening situation or when the exact matching blood type is in short supply. This is because type O- blood cells lack antibodies to A, B, and Rh antigens.

Because type O is the most prevalent blood type and type O- blood is the universal blood type needed for emergency transfusions and immune-weak babies, type O is frequently in low supply and in great demand by hospitals. Minorities and different communities play an important role in meeting the ongoing demand for blood.

The O- and O+ personality types are in high demand. O- people account for only 7% of the population. However, O- blood is in high demand since it is frequently utilized in emergencies. O+ is in high demand too, because it is the most common blood type.

Donate blood: What to know before donating

If someone wishes to donate blood, they need to make sure that they match the standards and are adequately prepared.

To begin with, they need to locate a blood bank or blood drive and schedule an appointment. They also need to ask if there are any special requirements for donors, as well as what kind of identification they’ll need.

They’ll have to be:

  • 16 years old to donate whole blood and 17 years old to donate platelets.
  • At least 110 pounds (50 kg).
  • Being in good health and feeling good
