Medical Alert Cards

Create Your Free, Customized Medical Alert Card

If you have red blood cell antibodies, carrying a medical alert card is a simple but important way to help protect your health.

Red blood cell antibodies can complicate blood transfusions, even if you are no longer pregnant. Receiving incompatible blood may cause a hemolytic transfusion reaction, which can be serious or life-threatening.

Knowing your antibody history helps your healthcare team and blood bank identify compatible blood and plan ahead if you ever need a transfusion.

Important: Red blood cell antibodies can become undetectable over time, but they may still be clinically significant. Always tell your healthcare team about any antibodies you have had in the past, even if your current antibody screen is negative.

Allo Hope Foundation offers a free, customizable medical alert card to help you keep this important information readily available.

Complete the form below to create your card. Once submitted, you can view, download, or print your personalized PDF.

Another Way to Stay Prepared

Add Your Antibodies to Your iPhone Medical ID

Did you know your iPhone has a built-in Medical ID feature? It allows you to save important health information, including your red blood cell antibody history, where emergency responders may be able to view it even when your phone is locked. Setting it up takes just a few minutes.

How to Set Up Your Medical ID

1

Open the Health App

On your iPhone, open the Health app (the white icon with a red heart).

2

Find Your Medical ID

Tap your profile picture or initials in the upper-right corner, then select Medical ID.

3

Tap Get Started or Edit

If this is your first time creating a Medical ID, tap Get Started. Otherwise, tap Edit to update your existing information.

4

Enter Your Antibody History

In the Medical Conditions or Medical Notes field, enter your known red blood cell antibodies, including any historical antibodies. Use the exact names documented by your blood bank.

5

Include Other Important Details

Add your confirmed blood type, medications, allergies, and emergency contacts. If possible, include the name of the hospital or blood bank that maintains your antibody records.

6

Enable Emergency Access

Scroll to the emergency access settings and turn on Show When Locked. You may also enable emergency-call sharing where available. Tap Done to save.

What Should I Write About My Antibodies?

You can use wording like the example below, replacing the antibody names with your own confirmed results.

RED BLOOD CELL ALLOANTIBODIES: Anti-D and anti-K (example only). History of clinically significant red blood cell antibodies. Notify blood bank before transfusion. See antibody history in medical records.

Important: Your iPhone Medical ID is an additional safety measure, not a replacement for your medical alert card or blood bank records. Always inform your healthcare providers of your antibody history, especially before surgery, delivery, or any potential blood transfusion. Information visible from the Lock Screen may also be accessible to anyone with physical access to your phone.
