Blood Type Patches
About this Collection ▼
Blood type patches are a critical piece of any tactical kit. In an emergency, a clearly visible blood type patch allows medics and first responders to make faster, potentially life-saving decisions about blood transfusions. At BuckUp Tactical, we carry PVC and embroidered blood type patches for all eight major blood types — all with Velcro backing for easy attachment to plate carriers, vests, and bags.
Available Blood Types
- O Positive (O+) – Most common blood type
- O Negative (O-) – Universal donor — the most critical patch to wear
- A Positive (A+) – Second most common
- A Negative (A-)
- B Positive (B+)
- B Negative (B-)
- AB Positive (AB+) – Universal recipient
- AB Negative (AB-) – Rarest blood type
Where to Wear a Blood Type Patch
The standard military placement is the left shoulder strap or left chest panel of a plate carrier or tactical vest — where it's easily visible to a medic. See our patch placement guide for more options.
