What’s Your Type?
There are four major blood types: O, A, B, and AB. Your blood type is determined by the presence or absences of two antigens A and B. An antigen is a substance that stimulates your immune response. Your immune response is how your body protects itself against harmful substances by recognizing and responding to antigens. Rh factors, which can be either positive or negative, are the third antigen that makes up your blood type. Rh is the protein found on the surface of a red blood cell. If your blood has the protein, you’re Rh positive.
According to Eat right 4 your health by Dr. Peter J. D’Adamo. Type O is the oldest, Type A evolved with agrarian (farming) society; Type B emerged as human migrated north into colder harsher territories and AB is considered the most modern type and is very rare
The American Red Cross notes:
- Type O positive: As the most common blood type.
- Type O negative: As the universal red cell donor
- Type AB: As the universal plasma door
The mix of the different blood types varies by Ethnic groups. See chart below:
To determine your own blood type there are 5 different ways you can do so:
- Set an appointment with your primary doctor
Chances are if you already have blood work on a file and it has been tested, your blood type will be listed among the results. If not your primary doctor can order the test. It may take a day or two to receive the results. Call your doctor for a copy of the results.
- Donate Blood
You can donate blood at your local donation center, hospital, church or school as these locations typically host blood drives. When you go in, ask if they can tell you your blood type after the donation is processed. If they are unable to provide you with the information on the same day, ask if they can call you in a few days with the results. Some centers may not provide this service so please call in advance and ask questions prior to choosing a location.
- Purchase a Blood Type Testing Kit
A testing kit can be found and purchased at your local CVS, Wal-Mart or Walgreens. The great thing about the kit is all the items you will need to find out your blood type comes inside; an alcohol pad to clean your finger, a sterile disposable finger lancet to obtain a few drops of blood. You will then place the drops of blood on the special card and add a little. In just a few minutes, you’ll have a card, which shows you what antigens you have in your blood (which you can compare to a chart in the instructions to determine your blood type). Even better, some kits come with a laminating sheet so you can carry your blood type around with you. I wouldn’t be surprised in a few years if someone creates an app to determine your blood type. That would be pretty cool and a little scary..lol
- Use a blood type calculator
There are several websites you can use to determine your blood type through calculation. Before using this calculator you will need to know both of your parents’ blood types.
A great website to determine your blood type is:
As it allows you to determine the possible blood type of a child given the blood type of the two biological parents or the possible blood type of one biological parent, given the blood type of the child and the other biological parent. Please note these calculations are based on theoretical principal and the best way to determine your blood type is through a blood test.
The possible blood type combinations are listed below along with the types of blood types they create:
- O parent x O parent = O child
- O parent x A parent = A or O child
- O parent x B parent = B or O child
- O parent x AB parent = A or B child
- A parent x A parent = A or O child
- A parent x B parent = A, B, AB or O child
- A parent x AB parent = A, B or AB child
- B parent x B parent = B or O child
- B parent x AB parent = A, B or AB child
- AB parent x AB parent = A, B or AB child
We hope this post will encourage those who don’t know their blood type to go out and get the info. Knowing your blood type is essential from a medical standpoint and is critical in situations where you might need a blood transfusion.
