Blood Group A Wallet Card

Let first responders know that your Blood Group is A with one of these Blood Group Wallet Medical Cards.

The cards measure 86mm by 54mm which is the same as a credit card (3.38 inches by 2.13 inches) so will fit easily into a purse or wallet.

Blood group A is one of the four major blood groups in the ABO blood group system. People with blood group A have A antigens on the surface of their red blood cells, which means their immune system recognizes these antigens as "self" and does not produce antibodies against them. However, they do have antibodies against the B antigens that are not present on their own red blood cells.

Blood group A can be further classified into two categories: A positive and A negative. A positive means the person has Rh factor protein on the surface of their red blood cells, while A negative means they do not have this protein.

Knowing your blood type is important because in case of a medical emergency where blood transfusion is required, it is necessary to match the blood type of the donor with the recipient to avoid any adverse reactions. In addition, research has suggested that a person's blood type may have implications for their health, including the risk of certain diseases.

A Blood Group Wallet Medical Card can be useful for anyone who wants to communicate their blood type quickly and easily in case of an emergency or accident. This includes individuals with medical conditions or allergies, athletes, travelers, and those who work in high-risk professions. People who have rare blood types or who have experienced blood transfusions in the past may find it especially important to carry a Blood Group Wallet Medical Card. Additionally, family members of people with rare blood types or medical conditions may choose to carry a card in case of emergencies. Ultimately, anyone can benefit from carrying a Blood Group Wallet Medical Card, as it can provide crucial information to medical professionals when time is of the essence.
