What is the difference between the LTOWB Kit and buying the Collection and Administration Sets separately?
The LTOWB Kit bundles the Collection Set-V (83-0031) and Administration Set-V (83-0030) into a single purchase — simplifying procurement, co-locating all components, and ensuring the unit has both the donor and recipient sides of the transfusion available together. Purchasing separately allows for unit-specific configurations where donor and recipient kits are managed at different positions or carried by different personnel.
How does LTOWB differ from standard fresh whole blood (FWB)?
LTOWB (Low Titer O Whole Blood) specifically refers to type O blood from donors who have been pre-screened and confirmed to have low anti-A/anti-B antibody titers (≤ 1:200). Standard FWB includes any blood type from any volunteer donor, which carries higher risk of transfusion reactions if blood types are mismatched. LTOWB is safer for transfusion to unknown-type or non-type-O recipients — the key advantage of walking blood bank programs using pre-screened LTOWB donors over ad hoc FWB collection.
Does the NAR LTOWB Kit include cold storage capability?
No. The LTOWB Kit is designed for immediate fresh whole blood collection and transfusion — not cold storage. The blood is drawn from a warm donor and administered immediately (within minutes to a few hours). For cold-stored whole blood (CSWB) requiring transport and multi-day storage, separate cold storage containers and validation protocols are required. The LTOWB Kit is optimized for the walking blood bank model where blood is fresh at point of use.
What training is required to use the LTOWB Kit?
Providers using the LTOWB Kit should complete formal walking blood bank training, which covers donor pre-screening interpretation, phlebotomy technique, blood typing verification, Y-type blood administration set setup, documentation requirements, and adverse event recognition. USSOCOM and TCCC training curricula include walking blood bank modules. The 18D (Special Forces Medic), Navy Corpsman, and PJ pararescue training pipelines include this competency.
Can the LTOWB Kit be used by civilian EMS or disaster response teams?
Yes. Walking blood bank protocols using LTOWB have been adopted by some civilian mass casualty disaster response programs, special operations law enforcement teams, and remote expedition medicine programs. The key requirement is a pre-deployment or pre-event donor screening program to identify type O low-titer donors within the team, combined with appropriate medical direction and training. The clinical evidence for LTOWB efficacy in hemorrhagic shock applies equally to civilian and military trauma contexts.
Is the NAR LTOWB Kit CoTCCC-recommended?
Whole blood transfusion using pre-screened LTOWB donors is consistent with TCCC's damage-control resuscitation guidelines for haemorrhagic shock. CoTCCC issues guidance on resuscitation principles; always verify current TCCC guidelines for blood product recommendations applicable to your unit's protocols.
Who is authorised to use the LTOWB Kit?
The LTOWB Kit is intended for use by trained medical personnel — SOF Medics (18D), Physicians Assistants, 68W Combat Medics, and equivalent civilian roles — under appropriate medical director authorisation and ASBP protocols. Lay responders should not perform whole blood transfusions.
What is the shelf life of the CDP blood bag included in the kit?
The CDP (citrate-phosphate-dextrose) anticoagulant blood bag is rated for single-use collection. Shelf life depends on storage conditions; once blood is collected, ASBP protocols specify maximum administration windows. The kit's SF-518 and ASBP 572-EWB V29 documentation cards guide compliant processing.
What are the NSN and procurement details for the LTOWB Kit?
SKU: 83-0029. NSN: 6515-01-707-3174. Available through North American Rescue's GSA/ECAT contract. The LTOWB Transfusion Set (for administration) carries NSN: 6515-01-684-9074, and the LTOWB Collection Set NSN: 6515-01-686-2423. Contact MED-TAC International for unit pricing.
Can the LTOWB Kit be used alongside the LifeFlow PLUS for rapid administration?
Yes. The LTOWB Kit's Y-type IV set with 170–260 µm filter is compatible with rapid infusion devices. The LifeFlow PLUS (SKU: 30-0287, NSN: 6515-01-703-0004) can administer 1 unit of whole blood in under 2 minutes when paired with appropriate IV access — a recommended combination for DCR in haemorrhagic shock.
