Molecular Detection of Mycobacterium tuberculosis in Donor Tissue
Test Code
VBMTB
Description
In very rare instances, donor derived tissue may contain M. tuberculosis complex (MTBC) that can cause infection in transplant recipients. This molecular test may be used to qualitatively identify the presence of MTBC in donor tissue.
Current US guidelines do not require testing for MTBC on donor tissue. This assay is performed on a research use only (RUO) basis, and has been validated as a lab-developed test (LDT) for certain sources using clinical diagnostic testing criteria (CAP/CLIA).
Collect
Processed donor samples
Unacceptable Conditions
- Specimens not frozen at -70oC or below
- Missing shipment manifest/requisition with specimens or incomplete specimen labeling and documentation

Storage Transport Temp
Specimens should be kept at -70 oC or below, and shipping much be overnight on dry ice.
Specimens must be packaged, shipped, and transported according to the current edition of the Internaltional Air Transport Association (IATA) Dangerous Goods Regulation. Follow shipping regulations for UN 3373 Biological substance, Category B when sending potential MTBC specimens.
