O Blood Types, Your ABO Gene, and COVID-19 Complications

Written by Joe Cohen, BS | Last updated:

What’s your blood type?

When I ask someone this question, the majority of the time they answer saying that they don’t know.

But it’s more important than you think.

Knowing your blood type can actually help you answer a burning question you’ve had since the start of the pandemic: what’s my risk of getting Coronavirus?

You might think that your blood type is just a way to determine what blood donations you can give or receive. But there’s more to it.

You see, proteins found on the surface of blood cells determine your blood type, but these proteins are not just found on blood cells. You can find them on many different types of cells in your body, and they have extremely complex roles in many different body functions.

For example, people who don’t have an O blood type (A, B) are at an increased risk for:

  • Cardiovascular disease (heart disease, heart attacks, stroke, blood clots)
  • Cancer (stomach, pancreatic)
  • Infections (h. pylori, severe malaria)

A recent groundbreaking scientific study just linked blood type and your ABO gene to the Coronavirus.

This study examined genes directly associated with COVID-19 and determined that people with variants of the ABO gene that are not in the “O” blood type are more susceptible to contracting Coronavirus and developing complications.

Around 50% of people have the protective O blood type. However, if you’re not in that lucky 50%, you should be more cautious.

I am blood type “A” so I need to be more careful.

Blood Type and ACE2 Receptors

As you probably know by now, ACE2 receptors are the main point of entry for the Coronavirus, as it hijacks and invades your cells by binding to the receptors.

Your blood type determines how easily the virus can bind to your ACE2 receptors.

The study found that blood type O actually inhibits the binding of Coronavirus to your ACE2 receptors, meaning people with that blood type are less susceptible to contracting the virus and developing severe complications.

On the other hand, blood type A is the complete opposite and has no inhibiting mechanisms to stop COVID-19 from hijacking your cells through your ACE2 receptors.

Understanding your ACE2 gene variant can help you determine whether or not you have an overexpression of the receptors, resulting in more doorways for Coronavirus to enter.

But your ABO gene is the deciding factor on whether or not it’ll actually get through the doorway. That’s why it is extremely important to learn what ABO gene variant you carry, so that you can implement lifestyle changes to prepare your body.

If you don’t have your labs, your genetics can be used to tell you if you have blood type “O” or not (but it’s always best to verify with a blood test).

Since I have blood type “A”, my genetics show that I have higher risk based on my ABO gene.

Although the result seems pretty grim, I’m actually extremely happy that this study was released! It’s given me even more power over my health and body, and now I know there are some specific supplements I need to take to counteract the negative effects of my blood type and the genes that have been directly correlated with COVID-19.

If you know which genes or variants are increasing your risk, you can determine the best changes to make just by looking at the suggestions given to you in the Personalized Genetics Blog or in your COVID-19 Report.

We’ve recently updated the COVID-19 DNA Report to include the latest findings in the scientific study, which includes the ABO gene and 3 other genes.
