Industry-leading experienced and certified drivers
U.S. Messenger has fully trained and certified drivers to safely and correctly deliver your essential medical items. We keep our driving staff’s Blood Pathogen and other training subjects up to date annually by employing full-time Driver Development Managers who are trained and certified instructors for nationally-recognized organizations.
All medical specimens and samples are transported in coolers with the proper temperature controls requested by the shipper or required by the laboratory. Our drivers use smartphones powered by CAT to keep track of each of your shipments — putting our dispatch team in every driver’s seat.
Bag & Tag System
Bag & Tag is considered the safest and most effective inventory control method in the industry because it limits multiple human contacts with specimens and provides a permanent adhesive, sealed by your client at the time of packaging, which can only be opened by the laboratory. This program has been created in conjunction with several laboratories, clinics, hospitals, and physicians.
How does it work?
- Bags are sealed by staff at the pickup location. Once sealed, the bags can only be opened by the recipient laboratory.
- Our couriers scan the bar code at the time of pick up, providing a permanent record of the transaction.
- Specimens are inventoried and confirmed by the recipient laboratory upon arrival.
