The NAR Low Titer O Whole Blood Collection Set-V (SKU 83-0031) is the donor-side component of NAR's walking blood bank LTOWB system — designed to pre-screen, identify, and collect one unit of type O low-titer whole blood from a pre-screened donor in operational forces. It pairs with the LTOWB Administration Set-V (83-0030) to complete the field transfusion cycle for hemorrhagic shock resuscitation.

Product Overview
The donor side of a walking blood bank operation requires a structured kit for pre-screening the donor's blood type, performing phlebotomy under field conditions, and labeling and preparing the collected unit for immediate transfusion. The NAR LTOWB Collection Set-V is purpose-built for this function, providing all components for a complete field blood draw from a pre-identified low-titer type O donor.
The 'V' designation traces to the Valkyrie walking blood bank program developed by USMC MARSOC (Marine Raiders), which systematically implemented LTOWB collection and transfusion at the unit level for far-forward combat operations. The program demonstrated that pre-screening service members before deployment for low-titer type O blood type and training corpsmen to activate the blood bank at point of casualty significantly improved resuscitation outcomes compared to crystalloid-only or delayed component therapy approaches.
The Collection Set-V includes a blood typing/screening component, phlebotomy supplies, a labeled collection bag, and documentation materials. The design simplifies the collection process by reducing the number of discrete steps and supplies required — NAR's validation research showed that simplified procedures under stress conditions (low lighting, noise, casualties, time pressure) improve first-attempt success rates and reduce procedural errors.
This set is designed to be paired operationally with the LTOWB Administration Set-V (83-0030) or purchased as part of the complete LTOWB Kit. The LTOWB Kit combines collection and administration components for units that want a single-purchase walking blood bank solution. For units with separate donor and recipient management workflows, the individual Collection and Administration sets can be purchased independently.
