There are very few people who actually know what their blood type is. It is incredibly common for people to not know their blood type. However, it is not necessarily the best thing. Finding out what your blood type is may not actually be required of you for any reason, but it is a good idea to know what type of blood you do have. Here are some reasons why it’s important to know your blood type.

Emergency Card

It is a good idea for almost everyone to have an emergency card for themselves. On it, you should include your name, date of birth, home address, contact numbers, and whether or not you have a preference as to what hospital you would like to be sent to. In addition, it is a good idea to include your blood type on the emergency card. Although the hospital is likely to check you to determine what type of blood you have, writing down your type can help make the process go much quicker for the doctors that are treating you.


When you make the decision to get married, it is important to know what blood type the both of you are. The reason is because there are certain blood types which cannot be mixed when creating a new baby. Type A and Type B should not be mixed. It is also important to find out if you have RH factor blood. RH+ and RH- blood should also not be mixed. Mixing these blood types can cause a child to experience a number of different health problems. This is the reason that many states require blood testing among those who are applying for marriage licenses.

Eating According to Blood Type

There are many people who make the decision to eat in order to please their blood type. Certain blood types may be more prone to certain health conditions, such as diabetes or heart disease. Eating certain foods can help you prevent these health problems from affecting you. People with certain blood types may also become more satisfied by eating certain foods. Although some blood types should remain vegetarian, there are others which should avoid eating carbohydrates, for the most part. You may be able to live longer and feel healthier when you make the decision to go on a diet that is designed solely for your blood type.

These are just a few of the many reasons to find out what your blood type is. If you are not sure, then you may want to think about visiting your doctor in order to learn. Keep in mind that there are also home test kits to determine what your blood type is. It is also possible to determine your blood type without any testing by finding out what your parents and other family members have, but this is not always a surefire way to learn blood type. The main key is to make sure that you know what type of blood you do have. You never know what type of position may require you to know what your blood type is in the future.
