Storage/Transport TemperaturePreferred temperatures for storage prior to and during shipping to ARUP. See Stability for additional info.
Whole blood: Refrigerated. Buccal brush: Ambient.
Unacceptable ConditionsCommon conditions under which a specimen will be rejected.
Whole blood, bone marrow, buccal swab, or saliva post transplant. Plasma, serum
RemarksAdditional specimen collection, transport, or test submission information.
Posttransplant results will be compared to pretransplant recipient and donor genotypes, therefore, donor and recipient specimens must be obtained and genotyped before the transplant even occurs. If transplant event occurred prior to specimen collection, dry buccal brushes (not bloody) are acceptable.
StabilityAcceptable times/temperatures for specimens. Times include storage and transport time to ARUP.
