Do not allow frozen specimens to thaw at any time during storage or transport, due to possible degradation of the DNA. Specimens submitted in polystyrene tubes are not acceptable. Specimens sent for Microbiology molecular testing require a dedicated sample and cannot be shared with other laboratories.
