Strange Facts About Rh Negative Blood


If life is thriving on this planet, it is all thanks to a few phenomena. Blood is one of the most important things that are essential for the life of humans on this planet. Have you ever wondered about strange facts about Rh-negative blood? If not, then this is the prime time to do so.

If we look at the human body, we will know that all the major functions are conducted by blood. It acts as the channel between all the body parts. Since it is the biggest transport mechanism in the human body, therefore, if it stops, then the body might suffer a huge loss.

Thus, if we look, we will come to know that even the energy produced by the food is transported to all parts of the body through blood. If all the blood is pumped out of the body, a person might die due to blood loss. Thus in this article, you will learn some strange facts about Rh-negative blood.

Blood and its types

We are well aware that the blood is the major part of the circulatory system of the human body. It circulates all kinds of materials from one organ to another, including energy for food, essential gases, and metabolites too. According to the available details, there are different blood groups that help us make divisions. Below we have mentioned some of the major blood groups:

  • Blood group A
  • Blood group B
  • Blood group AB
  • Blood group O

Blood groups with Rhesus factor

It is not only the blood groups that differentiate the blood type in humans. In fact, in the recent past, it was observed that the blood also has the rhesus factor. The blood group can either be positive or negative. Due to this, these four blood groups can be divided into eight different blood groups.

  • Blood group A+
  • Blood group A-
  • Blood group B+
  • Blood group B-
  • Blood group AB+
  • Blood group AB-
  • Blood group O+
  • Blood group O-

The nomenclature

Now you might be wondering why the name Rhesus factor is very much interesting. So let us tell you that since the Rhesus factor was first observed in the Rhesus monkey, therefore it has been named after that species.

What is the Rh factor

The properties of the Rh-positive and Rh-negative blood groups are completely different. Therefore, it is of the utmost importance that we study them thoroughly to get a command of the details and information regarding blood.

First of all, let us tell you that Rh is actually a protein. The presence of the protein makes the blood Rh positive, and the absence of the protein makes the blood group Rh negative.

Strange facts about Rh-negative blood

The pregnancy issues

First of all, if we talk about pregnancy cases, then we will come to know that since the contribution of the male and female partner is equal in the formation of the baby. Therefore the baby can either take the Rh type of father or the mother.

Thus if we go through the details, we will come to know that if a fetus has an Rh-positive blood type and is present in the womb of a mother with an Rh-negative blood type, then the chances of stillbirth and the death of the fetus are comparatively much higher. This can harm the erythrocytes of the baby.

The racial distribution

The Rh factor has also an association with the races. Thus, if we look at the statistical figures, we will know that the figures differ for Rh-negative blood owners in different races. Thus, if we look, we will come to know that a total of 15% of the white population has Rh-negative blood.

Also, if we talk about the African American community, we will know that the Rh negative blood owners decrease to only 5 to 10 percent. Moving on to the Asians, the statistical figures show that only 1 to 2 percent of the population has Rh-negative blood groups.

The percentages of the Rhesus factor in the ABO system

Since there are different blood groups, therefore it is important to study their reaction with the Rhesus factor. Thus, if we go through the details, we will come to know that the people belonging to Blood group O have the highest Rh negative percentage, which is marked as 7%.

On the other hand, the figures decrease to 6% for people with blood group A. The blood group B owners only have the individuals with Rh negative factor upto 2% only. Also, if we talk about the AB blood group owners, then among them, the number of Rh-negative blood owners is 1% only.

The highest Rh negative rate

People surely love to go for the remaining details. Thus, if we look, we will come to know that the people with the highest Rh negative blood groups belong to a European branch. They are named Basques. Considering the European rate of Rh-negative blood group, we will know that the Basques have almost double the count, which is not a normal factor.

The USA statistics

If we talk about the statistics of the USA regarding the Rh-negative blood group owners, we will know that the figures are slightly different. The people with AB- blood groups, are 0.6 percent, which is the rarest blood group to find in the US as the blood group with B negative has 1.5%. The O-negative blood owners in the USA are standing at the mark of 6.6 percent. The A negative blood group owner only had the figures of 6.3% in the USA.

Why go for the Rh factor

Determining the Rhesus factor is of the utmost importance because it provides insight during the blood transfusion regarding effective management and categorization. Also, several biological factors must be considered.


The strange facts about Rh negative blood groups are surely mind-blowing. Especially the statistical figures are of the utmost help and assist in making healthy decisions. Also, you can easily categorize and arrange the blood groups with the help of the Rhesus factor.
