The NAR Low Titer O Whole Blood Kit (LTOWB) is North American Rescue's complete walking blood bank solution — combining the LTOWB Collection Set-V and LTOWB Administration Set-V into one integrated kit. It provides every component needed to pre-screen a donor, collect one unit of low-titer type O whole blood in the field, and immediately administer it to a hemorrhagic shock casualty — the complete far-forward blood transfusion capability in a single purchase.

Product Overview
Blood transfusion at or near the point of injury has been the most impactful advance in combat casualty care of the past two decades. Studies from Iraq and Afghanistan consistently show that early whole blood administration — delivered within minutes to hours of injury — dramatically improves outcomes in casualties with hemorrhagic shock. The challenge has been logistics: maintaining a cold-chain blood supply in austere, far-forward positions is often impossible. The walking blood bank concept solves this by using the unit's own pre-screened personnel as the blood supply.
The NAR LTOWB Kit is the operational realization of this concept. By combining collection and administration into one purchase, NAR eliminates procurement complexity for medical officers building unit-level walking blood bank capability. The kit is pre-assembled, individually sterile, and includes the documentation materials required to complete the LTOWB transfusion chain from donor draw to recipient administration with full ASBP chain-of-custody compliance.
The Valkyrie (USMC MARSOC) and ROLO (75th Ranger Regiment) programs validated this capability at the operational force level. Multiple publications in the Journal of Special Operations Medicine (JSOM) and Prehospital Emergency Care (PEC) have described successful LTOWB transfusions in the field using walking blood bank protocols, with outcomes superior to crystalloid-only resuscitation. The CoTCCC's recognition of whole blood as the preferred resuscitative fluid directly reflects this body of evidence.
Operational Planning for LTOWB Walking Blood Bank
- Pre-deployment: Screen all personnel for blood type; identify and register type O low-titer donors through laboratory testing
- Deployment readiness: Maintain one LTOWB Kit per anticipated casualty position; brief all donors on activation procedure
- Activation trigger: Class III–IV hemorrhagic shock casualty requiring resuscitation beyond available crystalloids or component therapy
- Collection phase: Identify nearest pre-screened LTOWB donor; draw using Collection Set-V
- Administration phase: Establish 16g IV access in recipient; administer via Y-type set using Administration Set-V
- Documentation: Complete TCCC card, Blood Bag Sticker, and ASBP 572-EWB card; attach to casualty for CASEVAC
