Low-titer type O whole blood is the CoTCCC-recommended resuscitative fluid for hemorrhagic shock. The donor side of a walking-blood-bank operation needs a structured set for screening the donor's type, drawing under field conditions, and labeling the unit for immediate transfusion.
What organizes the donor side of a field blood draw into one purpose-built set?
The Collection Set-V is purpose-built for the donor function, providing the components for a complete field blood draw from a pre-identified low-titer type O donor — a blood typing/screening element, phlebotomy supplies, a labeled collection bag, and documentation materials. NAR's design reduces the number of discrete steps and supplies required, which their validation work tied to higher first-attempt success and fewer errors under stress conditions. Designed to pair operationally with the Administration Set-V (83-0030) or to be purchased as part of the complete LTOWB Kit. This is a provider-scope item — see the scope note below.
Provider scope: field blood collection is governed by training, credentialing, a unit blood program, and medical-director authorization. This set is intended for TCCC-qualified medics, corpsmen, flight and critical-care paramedics, physicians, and agencies operating an authorized walking-blood-bank program. It is not a consumer or first-responder item. Deploy only within your scope of practice and your unit's transfusion protocol.

LTOWB Donor Eligibility Criteria
| Criterion | Requirement |
|---|---|
| Blood type | Group O |
| Low-titer status | Anti-A / anti-B titers ≤ 1:200 (pre-deployment lab testing) |
| Infectious disease screening | Current military blood program testing (HIV, HCV, HBV, syphilis, etc.) |
| Physical eligibility | Standard blood donation eligibility (weight, hemoglobin level) |
| Donor identification | Pre-deployment donor registry maintained by unit medical officer |
Program Lineage
The “V” designation traces to the Valkyrie walking-blood-bank program developed by USMC MARSOC, which systematically implemented LTOWB collection and transfusion at the unit level for far-forward combat operations. The Ranger O Low-Titer Blood (ROLO) program in the 75th Ranger Regiment pioneered a parallel approach for Army Special Operations. Both demonstrated that pre-screening service members for low-titer type O status and training providers to activate the blood bank at point of casualty improved resuscitation outcomes over crystalloid-only or delayed component therapy.

When to Deploy Low Titer O Whole Blood Collection Set - LTOWB-V
- Walking blood bank (WBB) whole blood collection: The LTOWB-V Collection Set is the standard kit for collecting whole blood from pre-screened, low-titer type O donors in a forward environment.
- Special Operations forward surgical blood supply: SOF units operating beyond the resupply chain establish organic WBB capability — the collection set is the operational tool for building a forward blood supply.
- Damage control resuscitation preparation: Units implementing LTOWB DCR protocols pre-collect blood from donors before operations when MEDEVAC timelines create a high probability of hemorrhagic shock casualties.
- Mass casualty event blood supply augmentation: When blood bank supply is insufficient at a forward location, WBB collection provides an immediate augmentation capability.
- Role 2 and FSU blood program support: The collection set is used by the medical team to collect, label, and stage blood for the administration team.
How Low Titer O Whole Blood Collection Set - LTOWB-V Compares
LTOWB Collection Set vs. LTOWB Administration Set: These are two halves of one capability. The Administration Set delivers blood to the patient; the Collection Set draws it from the donor. Both must be present for a functional LTOWB program.
LTOWB Collection vs. standard blood bag collection: Standard blood collection systems are designed for blood bank environments with extended storage and processing. The LTOWB-V Collection Set is designed for austere forward collection and immediate-use whole blood — a different operational requirement and configuration.
LTOWB vs. component therapy (packed RBCs + FFP): Component therapy requires cold-chain logistics that are often unavailable in forward environments. LTOWB collected fresh from a WBB donor provides whole-blood resuscitation without the cold-chain requirement — it is both the preferred product and a logistically feasible alternative in austere environments.
Frequently Asked Questions
Q: Is LTOWB collection CoTCCC-recommended?
A: Yes. LTOWB from walking blood bank donors is CoTCCC-recommended as a damage control resuscitation product when available. The collection set supports the authorized collection process at the point of care.
Q: What donor screening is required before LTOWB collection?
A: Donors must be pre-screened for low anti-A and anti-B titers, infectious disease, and blood type O. This is a unit-level program requiring coordination with the military blood program and unit surgeon — not an improvised capability.
Q: What is the storage life of LTOWB collected with this kit?
A: Fresh whole blood collected with standard CPDA-1 solution has a 35-day storage life under refrigeration. In field conditions without cold storage, blood should be administered as soon as practical after collection. Follow your unit's blood program protocols.
Q: What is the NSN for the LTOWB-V Collection Set?
A: Contact MED-TAC International for current NSN and DLA/GSA procurement information for the LTOWB Collection Set and associated program equipment.
Q: Can the LTOWB-V Collection Set be used with the QUANTUM warming system?
A: The QUANTUM system is used for administration warming — contact MED-TAC International to verify collection set compatibility and recommended LTOWB program configuration with QUANTUM.
