We all share a concern for the safe and compatible transplant/transfer of donor organs and tissues. That concern translates into testing donor specimens using FDA approved screening kits and reporting data that confirms the release to transplant. VRL Laboratories sets itself apart by its commitment to its customers and its quality of performance. By providing an array of service offerings, VRL delivers consistent performance that exceeds our clients' expectations. 

Specimen Logistics

To safeguard the integrity of each specimen, blood samples are shipped to VRL using validated shipping containers which maintain the proper environmental conditions.  Using selected transportation companies, the specimens are tracked from our clients to VRL’s Specimen Management Department.

State of the Art Analysis

Upon receipt of all shipments, the donor specimens are checked for proper documentation and specimen integrity. Then, and only then, are they delivered to the appropriate testing department.  To meet the time sensitive needs of our clients, multiple infectious disease testing runs are scheduled 24 hours a day, 7 days a week.  Appropriate laboratory technologies, both automated and classical methods, balance the speed and efficiency of testing, all managed and performed by qualified laboratory technologists.

Test Results Reported/Transplant Decisions Made

Clients are free to choose from a variety of result reporting options. Options include email, electronic fax or information system interface. Clients are supported by VRL’s scientific and medical staff consultation.
